I need some advice on a project I am currently working on.
Some Background: I am building a device that mounts to a golf club and is controlled via Arduino. It send data about your swing to your smartphone using various sensors I have hooked up. Right now I am fairly far into the build and have everything working correctly, except I need a way to trigger the Arduino to start collecting data (Serial) and outputting it. I already have the bluetooth working with my phone and my phone reads the data but it is constant rather than when I push a button, per say. Any ideas on how I can hook a simple momentary button up to start reading from the sensors when I push it? Thanks in advance and I would appreciate other suggestions as to how I should go about this as well. XD
