The most popular Arduino microcontroller board is the Uno model. This is partly because it was one of the first, so it gained widespread adoption before further designs were created. The Arduino Uno is technically defined by its shape and the location of the input and output pins. Everything ...
The Arduino Nano matches that requirement and is ideal for USB-programming. You could also settle less for the 33 by 18 mm dimension, an example being the Arduino Pro Mini. Power Consumption This has to do with the amount of power that the board needs to function optimally. As a rule of...
My Arduino kit contains a Arduino UNO clone. This was bigger than I wanted so I settled on a cloned Arduino Nano from eBay which was about $10. This had the digital inputs I wanted, more than enough memory to hold the simple sketch I’d write, could be run from a 12V DC plug pac...
