PID and Arduino

Mikesolar · 01-16-13, 05:52 AM

Some of you have been using arduino for projects and I just picked up a Mega, BUT, I am a luddite when it comes to programming. When I went through DeVry electronics in the early 80s, I was interested in audio not computers so programming is hard for me to get my head around.

Therefore, the question, has anyone done any PID loops with the arduino? I want to make my heat pump controller or at worst control some pumps. Also, it seems they recommend 20ma max per pin for loads. Try getting a relay with that type of coil draw...uggg
