The brightness of the individual LEDs is controlled by the potentiometers. As an alternative to the buttons, you have got\u00a0the injection nodes in the corner bottom left. You can use them to specify the times a command is sent to the board. All you have to do is double-click on the corresponding node and select the time and also the days when the message should be sent. You can use it for example, to set an automatic lamp in a living room or an aquarium or activate special lighting on working days \u2013 fully automatically and much like the smart home concept.<\/p>","protected":false},"excerpt":{"rendered":"<p>The door of day 17 reveals another potentiometer.
