Review on 💡 Mini Nano V3.0 ATmega328P Microcontroller Board with USB Cable - Ideal for Arduino Projects and Programming by William Bell

These Arduino Nanos are the best. Works without error. I'm using one of these to build a logging switch - it's not there. This smart supper switch gets the brains of nano. The switch controls the electric heater that I used in place of my church cauldron. I swapped the ship's batteries + generator + windmill and unplugged it. A bit expensive, but no more heating costs! in the winter. The actual brain of the heating system (Arduino Mega) switches between the batteries and the generator. Switching with all registered actions is done by Arduino Anano! This is EXCELLENT for this app - 5 STARS!
