How To Make Diy Esp32 Cam Surveillance Robot

The DIY ESP32 Cam Surveillance Car is a great way to get started with building your own surveillance car. This project uses the ESP32 camera module to create a low-cost, low-power, and high-quality surveillance car. The project is perfect for anyone who wants to get started with building their own surveillance car, or for anyone who wants to add an extra layer of security to their home or business.

There are many reasons why you might want to consider adding a There are many reasons why you might want to consider adding a DIY ESP32 Cam Surveillance Car to your vehicle. One reason is that it can help you keep an eye on your surroundings while you're driving.

This can be especially useful if you're driving in a high-crime area or if you're worried about being followed. Another reason is that it can be a fun and easy project to do with your friends or family in your vehicle. One reason is that it can help you keep an eye on your surroundings while driving.

The ESP32-CAM is a tiny camera module with the ESP32-S chip that costs less than $10. The ESP32-CAM can be used in various IoT applications. The ESP32-CAM can be used to take high-quality still images and videos. The ESP32-CAM can also be used as a security camera.

The ESP32-CAM is ideal for low-power applications such as security cameras, drones, and industrial IoT applications. The ESP32-CAM can be powered from 5V or 3.3V and features a built-in USB-serial converter for programming and debugging.

The ESP32-CAM is ideal for security cameras, drones, and industrial IoT applications.

ESP32-CAMFeatures

• Onboard ESP32-S module, sustains WiFi + Bluetooth
• OV2640 camera with flash
• Onboard TF card slot, supports up to 4G TF cards for data storage
• Supports WiFi video monitoring and WiFi image upload
• Supports multi sleep modes, deep sleep current as low as 6mA
• The control interface is accessible via pin header, easy to be integrated and embedded into user products

ESP32-CAMApplications

This board can help us in developing projects that can see, and some impressive applications are:

An L298 module is a dual H-bridge driver module that is typically used for controlling motors. It is also used for other purposes such as voltage regulation and DC to DC conversion.

The module has two H-bridges that can be used to control the speed and direction of DC motors. The module can also be used to control the voltage and current of AC motors. The module is typically used for controlling motors

Now for powering the car we will use a 12v Li-ion battery, and connect accordingly

+Ve of battery to ---- +12 of L298N

-Ve of battery to ----- GND of L298N

For powering up the ESP32-CAM module we will use L298N's +5v as a source to do this Place the power jumper which is left on board.

connect :

L298N

+5 -------- 5v of ESP-32 CAM

GND -------- GND of ESP-32 CAM

IN1 --------- GPIO 14 of ESP-32 CAM

IN2 ---------- GPIO15 of ESP-32 CAM

IN3 ---------- GPIO13 of ESP-32 CAM

IN4 ----------- GPIO12 of ESP-32 CAM

since we are not going to control the speed of the car and will run at max speed place the ENA and ENB jumpers in place.

Before making chassis and setting motors, solder wires to Motors.

we carry used here a ready-made chassis which is easily available on the market, by the way, you can use any cardboard or easy plyboard cutout as chassis.

The diagram shows the hardware connection between Motor Driver Module and. Besides ESP32 cam, it may interface with any microcontroller such as PIC and etc.

Note: The Ground of the battery, Motor Driver Module and Arduino should be connected together.

The connection between: To see the result, download the sample source code in ESP32

Plug in the camera to the connector of the ESP32-CAM board.

Programming of ESP32-CAM is done via CP2102 USB to TTL UART serial converter Module. First, connect the USB to the TTL module with ESP32-CAM and short IOO pin of ESP32-CAM to GND according to the above diagram.

open the files menu in Arduino IDE. and then open preference and paste the link in additional boards managers URL and press

• Select the Board "Ai thinker ESP32-CAM"
• In the sketch uncomment the model of the ESP32 CAM you are using.
• Put in the WiFi credentials and Upload.
• Once the ESP32 is burned.
• Disconnect the GPIO0-GND jumper and reset the board, look at the IP printed on the Serial Monitor.
