433MHz Transmitter and Receiver - Part 3 - Arduino & VirtualWire Hack

55 Просмотры
In this video I'm using timers to generate a signal. I'm checking the generated signal by reading it and seeing it on the serial plotter (in the Arduino IDE). Then sending this signal via radio, receiving it and displaying it on the serial plotter again.

The main attraction: I've tweaked VirtualWire (a library typically used with transmitter-receiver modules) to work with sending and receiving back to the same Arduino, in a loop. So you don't actually need 2 Arduino boards to test the transmit-receive devices. Just one will do just fine :)

This is the third video of a multi part series. I advise you to watch the first 2 parts before this one (or at least the second part):
