Arduino: Blinking with Two Buttons

Two are better than one.

So let’s add a second button to your circuit and program that new input.

First, make a copy of your Tinkercad circuit that has one button and three LEDs.  Click here to learn how to make a copy of an entire circuit. 

  1. Add a second button to your duplicate circuit.  You can wire the new button next to your original button.
  2. In your program, add the second button as a new input with it’s own variable.
  3. Change your program so that pressing the second button will make the the LEDs blink in a different pattern from the first button.
  4. Use the Serial Monitor to have your code show this info:
    -that the first button was pressed
    -that the second button was pressed
    -each time one of the LEDs turns on
    This is what Serial Monitor looks like when press the first button:
