I want to build a device using an accelerometer. Press a button after a bike ride and have a light turn on if during the journey I managed to attain a certain acceleration.
Thinking of using some kind of flip flop and switch (using a circuit to hold one byte?), but need help with details, how to set up the circuit. I would need to be able to reset it too. The cheaper I can get my results the better.
I have started learning how to use Arduino board, can make simple projects.
