This project allows you to control an LED (or any other device) remotely using SMS commands via the SIM800C GSM module. The code is designed to turn an LED on or off based on the content of received ...

Build A Low Power SMS Based Vehicle Tracking System with A9G GSM+GPS Module and Arduino. Create a compact GPS tracker using A9G GSM/GPS module and Arduino. This project combines both cellular ...

This repository provides the hardware design, software code, and instructions for building a gas detection sensor module compatible with Arduino boards. The module effectively detects gas leaks and ...

Instead, he drew up a simple schematic that used an Arduino Nano, an FM radio module based on the TEA5767, and an audio amplifier based on the LM386.

Instructables user MakerBee's alert system uses an Arduino microcontroller and a dual-axis accelerometer. When your washer and dryer stop vibrating, the machine will know and alert you accordingly.

Here, Arduino’s (Uno R3) A4 (SDA) and A5 (SCK/SCL) pins are used for the I2C control, and the module is 3.3 V powered by the Arduino itself. It seems that external pull-up resistors for I2C lines are ...
