micro controller can give | Microcontroller › Arduino › rf module 315MHz interface with arduino › micro controller can give April 1, 2014 at 5:48 am #11436 Ashutosh BhattParticipant micro controller can give only two outputs high (5 V) and low (0 V) the only way to get variable output is to use DAC. but i wonder where your RF module comes in picture?
