For a project I am using Arduino Uno to power and control two stepper motors, two buttons and an LED matrix to form a "vendin machine", I have figured out the coding to use the two buttons to power the two separate motors repsectively, check file "Code for stepper motor controled by button"..
However I was wondering how to program the LED matrix to show a certain pattern when a button is pushed. I know how to program the LED matrix to show a pattern consistently when the arduino is turned on forever, but I do not know how to program different patterns to show at different times, ie when a button is pushed or to show one pattern for 5 seconds and then another patterns 5 seconds latter. Any help will be greatly appreciated file "matrixface" shows how I have used the LED matrix before.
