- Day 6 of Stay In and Make/Do - This DIY hand-washing timer plays you 20 seconds of Happy Birthday
#StayHome 🏠😷 #WithMe #microbit
You may think that counting to 20 isn't that hard, but try timing yourself. Make sure you're washing your hands for the required 20 seconds by building this hand washing timer that automatically plays music when you wave your hand over it.
Stay in and Make/Do is my series of daily projects to keep you entertained while you're staying at home. They're mainly electronics projects using the BBC Micro:bit (an affordable and easy to obtain little micro controller you can program in a really simple way), and these projects are suitable for all ages and ability levels - whether or not you've ever written code before or programmed anything!

Kudos for not setting off the music whilst it was close to the cat.
Am I one of the few people who prefers to concentrate on hand washing technique, ensuring full coverage, and that just naturally takes *more* than 20 seconds ?
Yeah, definitely better to focus on coverage rather than spending 20 seconds washing one finger! Perhaps version two should shout directions at you
You could set the light timer to be "1 < light sensor < 10" to avoid it going off in near absolute darkness.
That's a great idea! Genuinely annoyed I didn't think of that 🤣
@@HannahMakes oh awesome! I figured you'd leave it out to make that example simple enough... 😅
What app or website did you use for the code? Beginner here
Fantastic video! All useful fun tasks for classes to do as well!
In love with your shelves and storage though, where are they from? Been looking to tidy up my creative areas :D
Cheers!
My big folding cupboard with all the plastic boxes is made by a UK company called Storage4Crafts. It's probably my proudest purchase, especially now I've labelled all the boxes!
Hey, How can I add custom sound ? Basically I want to ad my voice recording, is it possible ?
There's no easy way to add your own voice - you can write your own tune in the MakeCode editor with the "play tone" blocks. If you wanted a voice recording, one way I can think of is to take the electronics out of those greetings cards that let you record a message. Then you could trigger that with the microbit somehow, perhaps with a relay. Hope that helps!
