Analog Input

  • File->Sketchbook->Analog->AnalogInput

val = analogRead(potPin); // read the value from the senso r

  • Potentiometer
  • photo-resistor
  • strain gauge

Analog Output

LED Dimming

  • File->Sketchbook->Examples->Analog->Fading

   analogWrite(ledpin, value);           // sets the value (range from 0 to 255) 

PWM (pulse width modulation)

  • lights, fading
