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).
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.
