Flush Reminder 7000

Should be pretty self explanatory here. I have two sons at home and needless to say they have a hard time remembering to flush. Why not build a tech solution for it.

The Flush Reminder 7000 has a PIR motion sensor and a buzzer. It will sense motion and then will mark when the motion ends. If the measured time between start and ending motion is > 10 seconds the buzzer will play the Eye of Tiger tone to help them remember to flush the toilet.

The Code.

I am still tweaking the sensor position and some of the code, but it is working pretty good for a 30 minute Friday Night Arduino project. Video of the Flush Reminder 7000 in action.
