Experiment 6: Reading a Button Press

Introduction

Up until now, we’ve focused mostly on outputs. Now we’re going to go to the other end of the

spectrum and play around with inputs. In Experiment 2, we used an analog input to read the

potentiometer. In this experiment, we’ll be reading one of the most common and simple inputs – a

push button – by using a digital input. We will use it to cycle through different colors on the RGB.

Parts Needed

You will need the following parts:

 1x micro:bit

 1x Micro B USB Cable

 1x micro:bit Breakout (with Headers)

 1x Breadboard

 8x Jumper Wires

 1x Momentary Push Button

 1x 10kΩ Resistor

 1x Common Cathode RGB LED

 3x 100Ω Resistors

Didn’t Get the SIK for micro:bit?

If you are conducting this experiment and didn’t get the Inventor’s Kit, we suggest using these parts:

Breadboard - Full-Size (Bare)

PRT-12615

micro:bit Board

DEV-14208
