I wanted make a simple bicycle logger. The Hardware would be simple, an arduino one button and one reed switch.
I want the arduino to start logging when i press the button and stop logging when when i press again. The arduino logs how many time the reed switch opens and the time when it happens so when i go to my computer i can download the data.
Although i have a basic knowledge of arduino coding i dont know how this could be done. Could anyone give me a similar code or some tips on hoe to go about it?
Also, would i need a EEPROM or can the data be stored in the arduino it self?
