Step 3: Analog and Digital Signals
Analog signals and digital signals are two types of signals used to transmit information in electronic communication systems.
Analog signals are continuous signals that represent physical quantities such as sound, light, and temperature. An analog signal can take on any value within a range of values, and it changes smoothly over time. An example of an analog signal is a human voice when speaking into a microphone. The microphone converts the sound waves into an electrical signal that varies in amplitude and frequency, which can then be transmitted through a wire or over the airwaves.
In Arduino we have 10 bit analog, analog signals are represented using analog inputs, which are capable of reading voltage values from 0 to 5 volts. These analog inputs can be used to read analog signals from sensors such as temperature sensors, light sensors, and accelerometers. For example, a temperature sensor may output an analog voltage signal that corresponds to the temperature of its environment, and the Arduino can use its analog input to read this signal and convert it into a digital value that can be processed by the microcontroller.
On the other hand, digital signals are discrete signals that represent information using a sequence of 0s and 1s. Digital signals are used to represent numerical values, text, images, and other types of data. Unlike analog signals, digital signals can only take on specific values, and they change abruptly in discrete steps. An example of a digital signal is a computer keyboard. When a key is pressed, it sends a digital signal to the computer that represents the corresponding character.
Digital signals in Arduino are represented using digital inputs and outputs. Digital inputs are used to read the state of a switch or a button, while digital outputs are used to control the state of a LED, a motor, or any other actuator. For example, a button can be connected to a digital input of the Arduino, and when the button is pressed, the digital input will read a high value (1), indicating that the button is pressed. Similarly, a LED can be connected to a digital output of the Arduino, and when the output is set to a high value (1), the LED will turn on, and when it is set to a low value (0), the LED will turn off.
In Arduino, analog signals are read using analog inputs(Pins A0 to A5) and digital signals are read using digital inputs(Pins D0 to D19) and controlled using digital outputs. These signals are used to interact with the physical world and control various devices and sensors.
Step 4: LED Blink
In this step, we are going to make a LED blink(ON and OFF) with 0.5Sec(500 Mili Seconds) interval.
- To add the components we just need to drag and drop the components on the work area as shown.
- Drag an Arduino Uno and a LED from the components list, you can see that we have lot many components in this list to play with, we are going to use few of this further.
- Now connect Anode of the LED to Pin 2 of Arduino and Cathode of the LED to GND of Arduino.
- I personally represent the GND/-Ve with black colored wire, 5V/3V/+Ve with Red and other signal wires with multiple colors.
- Now you have successfully made your first Electric Circuit Connection, Now let's code the Arduino
- Click on Code on the Top-Right side here you will find different blocks which you can drag and drop to build your logic.
- In Arduino, we have two main sections i.e on start/void setup() and forever/void loop()
- on start/void setup() - in this section whatever the logic we write will execute only once during the system boot(Power On).
- forever/void loop() - in this whatever the logic we write will be executed again and again repeatedly unless the power is off.
- Now in the on start I have dragged a print to serial monitor block, with this block we can print whatever the messages we want on our PCs screen via a serial monitor, you can see at the bottom we have Serial Monitor, we will see how it works.
- In forever I have dragged the set pin block and set the pin 2 to Hight following it I have added a serial monitor message block that says that the LED is ON.
- Then I added a Wait block which makes the flow(loop) wait for 0.5 seconds, and then set pin 2 to low followed by OFF message and wait for 0.5 seconds before turning LED ON.
- This code will first Print a messaage hello world(on start) and enters the forever loop.
- In forever loop first, Turn On the LED, print the message ON on the serial monitor wait for 0.5 sec(500 ms), and then turn off the LED, print OFF message and wait for 0.5 sec and the cycle gets repeated.

Note: In every section, I have added screen recorded demo of every demonstration in the form of .gif(Low quality) and .mov(HD Quality) you can refer them.
Step 5: Traffic Signal
In this step, we are going to make a traffic light containing Red, Orange, and Green lights. The traffic light stays in the Red and Green states for 5 sec and takes 1 sec to change from Red to Green i.e Orange state.
- First, drag all the components as shown, but before that do you know how to use a Breadboard? if not click to check these Instructables.
- Now click on the LEDs you will find a small pop-up window, here you can change the color of the LEDs, change the colors as per the demonstration.
- Connect
- Red LED to Pin 4 (Anode of LEDs)
- Orange LED to Pin 3
- Green to Pin 2 and
- All cathodes to GND
Now let's code it
- I have not used on start block but you can if you want to print any message.
- In the forever logic as you can see I have set different LEDs as per the demonstration statement
- First Turn on Red Light(Pin 4 - High)
- Wait for 5 sec
- Turn Off Red Light(Pin 4 - Low)
- Turn On Orange LED(Pin 3 - High)
- wait for 1 sec
- Turn Off Orange LED(Pin 3 - Low)
- Turn On Green LED(Pin 2 - High)
- Wait for 5sec
- Turn Off Green LED(Pin 2 - Low)
- and repeat .......

Step 6: Use Physical Hardware
Now we will use physical hardware and upload the code by downloading it from Tinkercad.
- You can get the components used in these demonstrations from the above supplies.
- Connect the components as per shown in step 5.
- In the codes section, you can also write the Arduino code in C++ by changing the Edit Mode. Tinkercad has the flexibility to build logic with Blocks, or Text code, or hybrid of both Blocks+Text Code.
- When you build logic using block you can get code for that from Text, we can just copy or click on the download icon to download the Arduino code.
- Now we need Arduino IDE, Click To Download.
- Open the downloaded code in Arduino IDE, Select the Board Type as Arduino Uno and com port as shown in the below video.
- Now you are all set, just click on the upload icon, if you have connected all the connections properly the lights will blink as per step 5.
That's how simple Arduino is!
You can upload any Arduino-compatible code in this way and make your own project
Step 7: Push Button
The above demonstration shows how we can use digital output but now we are going to see how we are going to use digital input.
- Connect the push button and Arduino as shown with a resistor of 10KOhm.
- One end of the push button to Pin 2
- Same end with a resistor and GND
- Another end to 5V
- We can change the resistance value by clicking the resistor.
- Here this resistor is going to act as a Pull-Down resistor, confused? Let me explain
- Suppose we press the push button, the input pin goes to High state i.e 5V, when we release it, the input stays on High state, which means always ON/High, that's why we connected 10K resistor between input and GND. Now the input always will be low except when the button is pushed.
- Similarly, we also have a Pull-Up resistor connection there we connect a resistor between the input and 5V.
Block Code
- In the forever section as you can see I have taken a read digital pin block, set it to read pin 2 and print the value on Serial Monitor.
Click to see my Pushbutton Demo
Step 8: 4-Button Piano
In this step we are going to make a 4-key piano, here we will take 4 push buttons and a buzzer. When we press any one key(Push button) we should get a tune that we have set to that key, different keys will have a different tune.
Connect the components as shown
- Buzzer to Pin 2
- Push Button 1 to Pin 4
- Push Button 2 to Pin 5
- Push Button 3 to Pin 6
- Push Button 4 to Pin 7
- GND, Resistors and 5V
Code
- In the Blocks, I am comparing the digital inputs of each pin 4, 5, 6, and 7 using if blocks, if the pin is High then the play speaker on pin block plays a specific set tune.
- You can change the tone value and duration.

Step 9: Variable Potentiometer
Now let's see how we can use Analog input, for this demonstration we are going to use a variable resistance potentiometer.
Connect the potentiometer to Arduino as shown
- Middle terminal to Pin A0
- Left terminal to GND
- Right terminal to 5V
Code
- In the forever section drag and drop the Analog read pin, and set it to A0, this block is placed inside the print serial monitor block.
- These will continuously read the analog signal from pin A0 and print its value on the serial monitor.
Start simulating, as you can see in the serial monitor as we rotate the knob the value changes between 0 to 1023.
Can you answer why the max value is 1023??
It's because Arduino has 10-bit Analog, 2 to the power 10 = 1024.
Click to see My Potentiometer Demo
Step 10: RGB Lamp
In this step, we are going to make a Multicolor RGB Lamp.
Let's use 3 potentiometers to change the value of Red, Green, and Blue and a Multicolor LED.
Connect the circuit diagram as shown
- LED cathode to GND
- LED Red to 11
- Led Green to 10
- Led Blue to 9
- Potentiometer 1 t0 A0
- Potentiometer 2 t0 A1
- Potentiometer 3 t0 A2
Code
- First create 3 variables named R, G, and B or Red, Green, and Blue
- Then drag the set pin and set the corresponding pins 9, 10, and 11 aligned with B/Blue, G/Green, and R/Red.
- In the block as you can see we are setting the values of the pins to the respective variables.
- reading the analog signal of Red, Green, and Blue - Potentiometers and setting(Storing) them to R, G, and B variables.
- But as you can see before storing the variable value I used mathematic block division - /.
- Since we get an analog value between 0 - 1024, but the RGB value must be between 0-255
- i.e R, G, B = 0-255, 0-255, 0-255
- So I have divided the analog value with the coefficient 4(from 1024/256).
Start simulating and rotating the different knobs, you will see a different color on different combinations of RGB knobs.

Step 11: Force Sensor
In this demonstration, we are going to connect a force sensor with Arduino.
As shown drag and drop all the components and connect
Can you name the resistor circuit in the comments, is it Step-Up or Step-Down?

Step 12: Moisture Sensor
In this step, we are going to make an Automatic Plant Watering System.
Let's drag and drop a Soil Moisture Sensor, a DC Pump(DC Motor), and an Arduino
Connect
Code
Start simulating and click on the sensor to change the value, you will see the motor starts on at low moisture and turns off at high moisture.
Click to see My Automatic Watering System
Step 13: Ultrasonic Sensor
In this section, we are going to make a digital scale using an Ultrasonic sensor, LCD Display, and Arduino Uno.
Drag all the components and connect them as shown
Code
Click to see My Digital Scale.
Buzzer to Pin 2
Push Button 1 to Pin 4
Push Button 2 to Pin 5
Push Button 3 to Pin 6
Push Button 4 to Pin 7
GND, Resistors and 5V
In the Blocks, I am comparing the digital inputs of each pin 4, 5, 6, and 7 using if blocks, if the pin is High then the play speaker on pin block plays a specific set tune.
You can change the tone value and duration.
Middle terminal to Pin A0
Left terminal to GND
Right terminal to 5V
In the forever section drag and drop the Analog read pin, and set it to A0, this block is placed inside the print serial monitor block.
These will continuously read the analog signal from pin A0 and print its value on the serial monitor.
LED cathode to GND
LED Red to 11
Led Green to 10
Led Blue to 9
Potentiometer 1 t0 A0
Potentiometer 2 t0 A1
Potentiometer 3 t0 A2
First create 3 variables named R, G, and B or Red, Green, and Blue
Then drag the set pin and set the corresponding pins 9, 10, and 11 aligned with B/Blue, G/Green, and R/Red.
In the block as you can see we are setting the values of the pins to the respective variables.
reading the analog signal of Red, Green, and Blue - Potentiometers and setting(Storing) them to R, G, and B variables.
But as you can see before storing the variable value I used mathematic block division - /.
Since we get an analog value between 0 - 1024, but the RGB value must be between 0-255
i.e R, G, B = 0-255, 0-255, 0-255
So I have divided the analog value with the coefficient 4(from 1024/256).
One terminal of force sensor to A0
The same terminal should be connected via a 10KOhm resistor to GND
and another terminal to 5V
It's a simple analog read set to pin A0 and prints on serial monitor.
Start simulating, and click on the force sensor to change the value.
Moisture sensor to Pin A0
VCC to 5V
GND to GND
Terminal 1 of motor/pump to GND
Terminal 2 of motor/pump to Pin 2
In the code as you can see we have analog read set to Pin A0
Comparing its value as < 300 (Means dry, less moisture less value)
You can change this value as per your requirement
and the if the value is less than 300 turn on the Pump(Pin 2 High)
else turn off pump(Pin 2 Low)
GNG of Sensor to GND
Echo to Pin 3
Trig to Pin 2
Vcc to 5V
GND of Display to GND
VCC to 5V
SDA to Pin SDA of Arduino
SCL to Pin SCL of Arduino
In on start section, we are printing the message 'Distance' on the LCD display at position 0th column and 0th row.
Then in forever section, we are setting the position to the 0th column, 1st row, and printing the ultrasonic value using read ultrasonic distance sensor block set to )Trigger Pin 2 and Echo Pin 3.
Start simulating and click on the sensor to change the distance, you will see the changing values to the LCD display.
Step 14: Servo Motor
-
In this step, we are going to see how we can control a Servo motor using an Arduino Uno.
Drag and drop all the components and connect
- Signal to Pin 2
- Power to 5V
- GND to GND
Code
- In this, I am rotating the motor from 0 degrees to 180 deg.
- Then from 180 to 120 deg and back to 0 deg.
Click to see My Servo Interface.
