This week we will take a look at what we can do with the General Purpose Input Output (GPIO) pins. You can do a lot of things using the pins at the bottom of the micro:bit including using touch, connecting them to tinfoil, fruit, headphones or other electronic components using crocodile clips. You can even use them with add-on boards like motor controllers, LED screens and more.

This week in micro:bit Monday we are going to discover how to use the micro:bit to detect light.

The micro:bit doesn’t have a light sensor built in, but we can use the LED matrix to detect how much light there is in a room. This can be then used to make a night light, or a light for the front of a scooter or bike or even just attached to you and it will turn on when it starts to get dark.

Let’s take a look at the code.

Within this post we are going to get to know what we can do with the LED matrix on the front of the micro:bit.

I will include code for the MakeCode, EduBlocks and microPython editors.

Lets get started!
