The things I used in the demonstration wereJula ansluta ”remote power switch”RF433 Mhz transmitter/RecieverArduino Uno Rev3External USB soundcard
Most of this are sold much cheaper in China and other countries from companies such as AliExpress.RF433 Mhz transmitter/Reciever – ($4.27 for 5 pairs)Arduino UNO R3 (Not genuine but compatible) ($3.04)
Happy hacking!
The code for the arduino can be found here
