Communication of analog data over RF between two Arduino microcontrollers. The analog data we use is from a light-dependent resistor being read by an Arduino Nano. We used the popular low-cost 433MHz ...

This is an example for the control of simple 433MHz radio sockets as you can buy them e.g. in a DIY store. It only works with models that use 10 little Dip switches to set the codes. Connect the VCC ...

Cheap 433 MHz wireless switches are a tempting way to enter the world of home automation, but without dedicated hardware, they can be less easy to control from a PC. That’s the position ...
