This 12X scale model Arduino runs on an actual Arduino

When you need a way to fit a microcontroller into a small space, the Arduino Nano is a great choice. If you need significant IO, the Mega is a go-to option. But if you need something physically very large, with the power and look of an Uno, the “Arduino Giga” by Zach Hipps of byte sized may […]
