Adding a button to your stoplight circuit
Adding input and an if/else statement to your stoplight
Part 2: Using your knowledge of circuit building and programing, build and program a stoplight circuit that does the following:
Program sequence:
Green light – waiting for input (the button to be pressed)
The button is pressed and then the light changes to
Yellow light – on for two seconds then off
Red light – on for three seconds then off
Returns to green light
After you have successfully wired and programmed a working stoplight circuit, bring it to Milstead or Varvil for us to review and grade.
