- 1 LED
- 1 resistor 680 ohms
Description
This example uses the AnalogOutput component to change the light intensity of an LED. AnalogOutput uses the Arduino function 'analogWrite', which produces a PWM (Pulse-Width Modulated) signal. This type of signal can be used to directly control the LED intensity. The following figure shows the connections.
For more information on the PWM outputs, the Arduino Playground is a good resource.
