Introduction: Tooth Brush Timer
the idea is to create a 2 persons timer for toothbrushing
for this, I used a microbit V1 .
It helps my kids to brush their teeth for the recommended duration.
If you have kids and a micr:bit and you want to ensure they have clean teeth; don't hesitate to copy my instructable.
1 micro:bit V1 version
1 laptop with internet access for makeCode
Step 1: Code Variables
the idea is to allow 2 persons using the microbit even they don't arrive in the bathroom on the same time.
The goal is to allow micro:bit doing 2 animations on the same screen.
For that, we will use the LED folder.
1/ when kid 1 arrives , he pushes the A or B button and the animantion begins for 3 minutes
2/ when kid 2 arrives, he pushes the second button and a second animations begins for 3 minutes as well.
so we need to creat 2 different variables (Timer and Timer 2)
Step 2: Animate Toothbrush
Due to the fact kids can arrive separately, we need to draw 2 differents animations on the same micro:bit.
Thus, we can't use the "basic" folder to create animation.
We need to use the LED folder of the MakeCode application and to draw toothbrush pixel by pixel.
Step 3: Save Your Batteries
in aim to save your batteries, micro:bit has to stop lighting LED when kids have gone.
As consequence, you have to shut off the screen at the end of the loops.
Step 4: Brush Your Teeth
you can now enjoy the micro:bit and ensure to have nice teeth ;-)
