The Arduino Nano
For Beginners, It’s Better Than The Uno When I first started tinkering with electronics and microcontrollers, the Arduino Mega 2560 is what I started with. For quick comparison, the Arduino Mega is very similar to the Arduino Uno, except it’s a much larger device (about the size of a Raspberry Pi or small iPhone) with…
