Create a Timer with the Arduino and micro:bit

This video will teach you how to attach a button and a buzzer to an Arduino Uno and a micro:bit. We'll work through the code in C for the Arduino and block code for micro:bit to create a custom timer. Using the buttons, you can set your timer up and set it to go. The Arduino and micro:bit will set off the buzzer when the set time is reached.

What You Will Learn
Attach hardware such as buttons and buzzers to the Arduino and micro:bit
Code your hardware
Incorporate loops and pauses in your code
Set up a beep test timer
Use the timer for home exercises
