Relay → Pin 4 LED & Buzzer → Pin 5 I2C Display Module → SDA (A4), SCL (A5) RF Receiver Module → Pin 11 (Data Pin) All the modules are powered with 5V from the Arduino. Below is the assembled image of ...

If you're looking to add wireless communication to your project, the Arduino nRF24L01 module combo is one of the most reliable and cost-effective solutions available. Whether you're building a DIY spy ...

While investigating the RF interface used in a series of cheap “smart” solar inverters [Aaron Christophel], created an Arduino library to receive inverter telemetry using a $2 RF module.

These include the Arduino, Raspberry Pi, and BeagleBone (Fig. 1). The tiny board in the upper right is a wireless expansion board for the Arduino.

It can be used to add Wi-Fi design elements to Arduino designs, while offloading the burden of TCP/IP stack and networking applications to the included xPico Wi-Fi module. The xPico Wi-Fi device has a ...
