2-Axis Joystick Documentation v1.1

Quick Start Circuit

This circuit works with the code below for the BASIC Stamp 2 to provide an RCTIME value for each axis

that relates to the position of the joystick. In this manner the two potentiometers are providing a

variable resistance for use with the RCTIME command. Caution: When using this circuit, do not use a

resistor value less than 220 Ω and do not apply more than 5 VDC through this resistor to the L/R or U/D

pins.

For more information on how to measure resistance using the BASIC Stamp RCTIME command, please

book, a free downlaod at www.parallax.com/go/WAM. The

PDF is also included in the BASIC Stamp Editor software’s Help file, which is a free download from
