Tea Timer with Arduino
A tea timer, or egg timer, using an ATtiny85-20PU chip with Arduino, running from batteries. You can of course buy a mechanical one, but I had some problems with those:
- They have a very loud ticking noise, which is not ideal in an office environment.
- They ring for only a split second and then go silent. If you weren't listening, you could easily miss it, and left wondering whether it had already rang, or you forgot to wind it up in the first place.
My solution aims to fix these two problems. Since it's digital, there is no operational noise, and it will keep beeping until you manually turn it off. On top of that, it also flashes, so you can still see it if you're wearing headphones.
Of course, another alternative is to just use a mobile app for this, but apps are lame. Dedicated tools are the way to go. Think of it as a kitchen accessory that you keep in the kitchen.
Tea is ready!
