Detect Closed Circuit

Project Goal

Build a device that will activate (blink LED) when a button has been pressed for a certain amount of time (acts as button debounce)

Hardware

• Arduino UNO

Design

• delay() function could not be used as the code needs to constantly be checking for an input.
• millis() funcion was used as the global timer that would blink the LED, and hold the time that the button has been closed to begin the LED blinking
• Used the built in Arduino LED
