The possibilities are endless. Baldengineer’s Arduino millis() Examples. Wiring/circuit diagram of this project is very easy. For example, to turn on digital pin 5 for one second then turn if off for one second repeatedly, the following code could be used. This example demonstrates the use of a pushbutton as a switch: each time you press the button, the LED (or whatever) is turned on (if it's off) or off (if on). array index and save as many cycles as possible.
