# Read pulse

This part is used to read the length of the next high or low signal on a given input pin (in units of 10 μs). When the part gains control, it will wait until a pulse is observed on the selected input pin. The result is stored in the named variable.

Choose the input pin from the drop-down list where you want to listen for the pulse input

Click on the high/low button on the part to switch between a high (rising) trigger or a low (falling) trigger for the pulse
