  • Bench PSU Power Supply from Old ATX with Arduino and LCD Monitor

    Great build! I am about to start one of my own, current modules and all! I have a question about the Vpower parameter in your code, the one based on the PURPLE wire of the PSU. Doesn't the nano have a regulator on it, thus taking that 5.22V and turning it into 5V? Due to this I am wondering where the correction comes into play, why it is neccassary. Any thoughts?
