Potentiometer component

This board consists of a standard shaft rotary potentiometer that provides a linear voltage output ranging between the microcontroller power rails. This can be connected to an Analogue to Digital input of the microcontroller in order to provide a control value.

Detailed description

No detailed description exists yet for this component

Examples

This example simply reads the value from the potentiometer sensor component and outputs the value to an LCD as a number in the range 0-255.

FC6 Icon.png EBM002 Example

The ADC bit depth can be increased to 10 or 12 bit depending on your device by changing the Mode parameter to 1 in the ReadPotentiometer component macro.
