I'm very much a newcomer to arduino and these forums, so please bear with me if I'm repeating something that has appeared before - I've tried searcing but no luck.
Is it possible to get the arduino to be running a program that gathers a small amount of sensor data and then later upon request sends that data over serial to a computer?
For example, I have 3 push buttons as inputs, I want to record the order of say the last 10 button presses. I then want to be able to go back to the computer, and be able to send the order to a terminal program to be saved.
Will the process of pluging the board in in any way stop the running program?
Would the best way to trigger the 'download' be to have a fourth button, which when pushed casues a string to be transmitted serially?
