SparkFun projects

In this tutorial we will learn how to display time using RTC DS1307 module and LED Display TM1637 and Visuino.

In this tutorial we will learn how to display the temperature using LED Display TM1637 and DHT11 sensor and Visuino.

In this tutorial we will learn how to make a simple step counter. This project is very useful in robotics.

In this tutorial we will learn how to make a simple Menu with buttons using Arduino and the I2C LCD. Watch the Video!

In this tutorial we will learn how to make a 4-Digit Countdown Timer displaying Minutes and seconds using Arduino.

In this tutorial we will learn how to get the weather data based on location from the internet using TTGO ESP32 and Visuino.

In this project, I will show you how to make IoT based Pulse Oximeter using ESP32, MAX30100, and Blynk Application.

In this project we will learn how to Turn the LED ON or OFF by pressing a button for 3s and also we can change its brightness while its ON.

It is a system made using ESP32 for monitoring the various factors required for plants to grow. It provides a live IOT dashboard that can be

A battery-powered LED module that communicates over zigbee

The main idea of this project is to simply make a light-up electronic greeting card with Hexabitz Modules.

The ability to control R.O.B. left with CRT televisions; until now! Blues Wireless breathes new life with remote instructions over cellular!

The 80's are back in text.....

This project uses an ultrasonic sensor to indicate the distance of any object from it.

This IMU-equipped pen is trained to recognize handwritten numbers

We need to sense intensity of light in many of our IoT/home automation projects. Here I explain a simple implementation of ambient sensor.

This explains how to control devices using BLE and smartphones.

This project demonstrates how to build a battery powered IoT Wi-Fi button in less than 10 min. The button controls HUE lights over IFTTT.
