ACTIVITY #1: CONNECTING AND TILT-TESTING THE MX2125
In this activity, you will connect the accelerometer module to the BASIC Stamp, run a
test program, and verify that it can be used to sense tilt.
Parts Required
Accelerometer Electrical and Signal Connections
Figure 3-3 shows how to connect the accelerometer module to the Board of Education's
power supply, along with the BASIC Stamp I/O pin connections you will need to make to
run the example program.

Listening to the Accelerometer's Signals with the BASIC Stamp
The two axes the MX2125 uses to sense gravity and acceleration are labeled x and y in
Figure 3-4. It will help if you set your board flat on the table in front of you as shown in
the figure. That way, the x and y axes point the same directions they do on most xy plots.
