Example 01 ‐ Switch and Lamp

This document describe a simple example, turning a LED on and off by switch. To not use any resistors, the input is set to PullDownInternal. This is the default value as well. If Sketch Made EASY is installed, it can be opened via menu: "File:/Example/SketchMadeEASY/Example/01-SwitchAndLamp".
