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.
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.
