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 … ...

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.

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 ...

🧠 Working Principle A potentiometer acts as the Synchro Transmitter, generating an analog voltage representing angle. Arduino reads this analog input. The value is mapped and sent to control a servo ...
