Write a program with the respective Tinkercad circuit design to control traffic lights like the example above. In addition to the example setup, you must have a sensor to check for incoming cars before allowing pedestrian crossing. You could use PIR or Ultrasonic distance sensors. An example design would be: No alteration to light sequence if cars are detected. Reset light sequence if there are no cars (resets to 'red for cars' allowing crossing) HINT: PIR sensor detects motion. HINT: Ultrasonic distance sensor measures distance in terms of time.
