Preset Resistor

A preset resistor is a smaller PCB mounted version of a potentiometer. These are useful where adjustment or configuration of a circuit needs to be made but such adjustment only occurs during building a circuit, not during normal use.

An appropriate value for the PICAXE system is 10k (do not use 100k devices).

Read a preset resistor value

This program will read a preset resistor (wiper connected to analogue input pin C.0, the ends of the preset resistor between V+ and 0V) and report the value read in the 'b1' variable.

Code Example:
main:	readadc C.0, b1		; Read the preset resistor value
	debug			; Display the value
	pause 1000		; Wait a while
	goto main		; Repeat
