The Arduino Uno Infrared Sensor Receiver Module detects infrared (IR) signals emitted by IR transmitters. It typically includes an IR receiver and a circuit to demodulate the received signals, ...

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.

As it is clear, the circuit consists of 3 main parts: Arduino-Nano (Controller), FM receiver module, and the audio amplifier. Figure 1, Schematic diagram of the digital FM receiver A-1. FM Receiver ...

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 38-KHz IRTR module is a compact design of an infrared transmitter and receiver board created with the help of a couple of inexpensive components. This builds off of the IR Decoder that we explored ...

Because some hardware setup is required to build up a functioning radio, an Arduino can be used to supply the voltage and control the radio chip. The 3.3-V power can be taken from the Arduino’s ...

To build an FM receiver, developers can use highly integrated chips, such as the TEA5767 from NXP. Here we describe an FM receiver with a frequency range of 76 to 108 MHz and 2 x 3 W stereo sound ...
