I am a newbie and looking to build a reaction timer combined with an accelerometer (to measure speed and power of a punch ultimately).
I have an Arduino Uno Starter Kit which I will build this circuit:
And have bought an ADXL335 which i want to also integrate into this circuit but I'm not sure how i connect both the push buttons (actually i will only use one for my project to 'stop' the timer) and the accelerometer as they both take up the analogue pins?
Once built i will attempt to play with both sketches and combine them, then cross my fingers tightly.
Any help would be appreciated.
