  Pull down Resistors - Momentary Switches
  
  Potentiometers
  
  PWM Pulse Width Modulation Dimming
  
  Study Examples:
  Basic - AnalogReadSerial
  Basic - DigitalReadSerial
  Basic - ReadAnalogVoltage
  
  For Next Time
  Keep your traffic light LEDs wired to Pins 4,5,6
  Wire a momentary switch with Pull Down Resistor to Pin 3
  Wire a potentiometer to Pin A0
  
  Save your traffic light sketch as Switch and Potentiometer
  
  Add code so that:
  1) with the switch not pressed the Green LED stays on.
  2) pressing the switch switches the signal to yellow for 3 seconds, then Red for 10 seconds.
  3) The Potentiometer adjusts the brightness of the Green LED
