    Darlington transistor POWER AMPLIFYING

    Hi all, I just couldn't find the answer on web so I had to ask you guys. Based on my understanding, input power is ideally equal to the output power of a circuit unless it is dissipated to heat. So I was looking at the ULN2003 Darlington controlling a 28byj-48 stepper motor using an Arduino...

    Hi everyone, I’m seeking guidance. I have a tricky situation which I don’t really know how to get out of. I want to design a system which would consume the least amount of power possible. The idea is to have an ESP8266 do a simple task every minute (updating a e-paper display) and sleep the...
