Playing with an Arduino UNO

A few years ago, I bought an Arduino Uno starter kit and I haven’t used much since then. Recently, I decided that is time to do something with it, so I build a simple logic gates simulator with LEDs and an LCD screen.

The code is in Github. Here are some pictures

I have selected the AND gate, so If I press both buttons the LED lights up.

There are 6 logic gates to choose from.
