The Silicon Labs Si4735 is a single-chip solution for receiving AM, FM, and shortwave radio. With a bit of hacking, it even supports single sideband (SSB). All you’ve got to do is provide it … ...

This project sets up an Arduino Nano as a wireless receiver using an NRF24L01 module. It listens for control packets from a paired transmitter, parses the incoming data, and displays the values via ...

The part list consists of one Arduino, two resistors, and one IR emitter. That’s right, an emitter. When an LED (IR or otherwise) is reverse biased it can act as a light sensor.

RC_Car Using two Arduino boards and a nRF24l01 module, I constructed a transmitter and receiver system. I wanted to begin with the fundamentals. In that case, I learnt how to use an Arduino to ...
