Goal is to replace this Ikea super cheap timer that works … well, as good as something manual that you paied less than 200 JPY (less than 2 euro). Not precise, sometimes doesn’t ring, or ring just the blink of an eye, so easy to miss…
The new timer will:
- Have a graphical LCD (bought one one year ago, never used it, needed a pretext, so…)
- Work on battery (1x 9v battery)
- Play music when it’s time
- Use a speaker and amp
- Possibly use a YMZ294 ?
- In fact something else but much better…
- Have an on/off system with a push-button, not a open/close switch In fact a tilt switch
- No arduino, but a simple atmega 328 (more than sufficient)
- Keep me busy a few days while allowing me to use some parts I bought long time ago and create a un-reasonable and out of price kitchen timer

This instructable will guide you through creating your own Arduino based Kitchen Timer. This is a quite simple project, requiring little or no programming or electronics knowledge, just the willingness to learn and fiddle – an ability most useful for modern man.
This kitchen timer is simple enough, press and hold a button and it will count up it multiples of five minutes, until you release the button. Upon doing so the timer will flash, and begin counting down. This timer includes an alarm and a display, with a piercing piezo buzzer to get your attention.
The arduino, laptop, protoshield, and USB Cable excluded; I took every electrical component from an old or broken device. Try to recycle things, its easy to get hold of broken electronics for free so make the most of it! See any jumpers on this design? No, paper clips are much better – cheap as chips and more sturdy too!
