Hi Experts,
I would like to control a 2ch relay wirelessly from arduino using 433mhz RF receiver/transmitter
my setup would be 433mhz transmitter on the arduino will send data to 433mhz receiver on 2ch relay module
I could not find any info/wiring instruction how to connect RF receiver to the relay module/
please give me some guide/data protocol. on 2ch relay module I have 4 pin: Gnd, in1, in2, vcc . And on 433mhz receiver I have 4 pin as well : gnd, data, data, vcc
Thanks
