The circuit we built contains 3 LEDs, a button made by Dylan, resistors and an Arduino. Each LED is connected to a pin of Arduino and a button. If a button is presses, a pin will light up the connected LED.

A short play

This exercise was fun but challenging. Because it’s for explaining to a 5 year old, we want to make the short play understandable and simple. When we wanted to explain the circuit clearly, we added something and then we found it made the play complicated. When we wanted to make the play simple and straightforward, we simplified the play but found it could not explain clearly. When we discussed together, we came up with various ideas and made props. It’s really fun.
