So i'm doing a small project that includes 2 different modules, a transmitter and a receiver. And i decided to use IR to transmit the signal. it works decent. But at idle, with or without sleep mode, my Nano uses about 25-30 miliamps of power. So my question is. Is there any advantage to use Rf instead? How is the power consumption compared between an IR receiver and an RF receiver?
I got some 433 mhz modules laying around here somewhere.
