Arduino Switch Controller Chat Control

Switch controllers can be used to turn devices on or off. They can operate a relay, or they can generate PWM signal. The On/off state can be used to turn on or turn off devices through relays, the PWM signal can be used to adjust the signal level, for example you can set the brightness of a LED or control the speed of a motor. You can learn more about PWM on the Internet. PWM in Ozeki can be adjusted in absolute numbers or as a percentage.

You can chat with the device at the Ozeki 10 as the video shows below.
