Web1 dec. 2024 · this code is supposed to read the state of a digital input pin via a pushbutton and output the state to an LED. i.e. when input is high, LED is on and vice versa Since … WebSwitch Nodes. A switch node reads in a data input, and based on the value of that input, sends the execution flow out of the matching (or optional default) execution output. There are several types of switches available: Int, String, Name, and Enum . In general, switches have an execution input, and a data input for the type of data they evaluate.

Web29 apr. 2010 · 2 Answers. "Tristate" means a state of high impedance. A pin can either pull to 0 V (sinking current, generally), pull to 5 V (sourcing current, generally), or become high impedance, like an input. The idea is that if a pin is in high impedance state, it can be pulled to high or low by an external device without much current flow.
