433MHz RF communication to a Raspberry Pi
27 March 2016 | Updated 1 July 2017
This post will explain how to get up and running with the 433MHz RF Transmitter Receiver modules to send radio frequency (RF) signal-codes from a transmitter device to a Raspberry Pi.
Relay switch modules
26 March 2016 | Updated 27 January 2018
Relay switch modules are used as high voltage AC switches by connecting a signal and DC power supply to it. These modules are made up by a relay (the ‘heart’), screw terminal connectors, a resistor, diode, capacitor, transistor and LED – making it perfect for electronic hobbyists to use in projects.
Laser Transmitter Receiver modules for sensing movement
