Resources and Going Further

Pulse width modulation is used in a variety of applications particularly for control. You already know it can be used for the dimming of LEDs and controlling the angle of servo motors and now you can begin to explore other possible uses. If you feel lost, feel free to check out the SparkFun Inventor's Kit which has examples using pulse width modulation. If you're ready to jump into coding immediately and have an Arduino, look at the PWM coding example here.

Feel free to keep exploring:

• Motors and Selecting the Right One
• What is an Arduino
• Analog to Digital Conversion
• Light
• LEDs
• IR Communication
• Interactive Hanging LED Array
