3. P2.4 P2.5 P2.6 P2.7 Left motor = P2.0, P2.1 Right motor = P2.2, P2.3
This controls the power from the
battery pack. The LED should light
when power is connected to the
circuit.
This should be OFF for programming.

4. This is the power rail for the sensor blocks provided.
+ve = 3.3 V = ORANGE
-ve = GND = BLACK
Access to Port 1, pins connected in increasing order from 1.0 to 1.7. These should generally be connected to BLUE wires from sensor blocks provided.

5. This switch selects the mode of operation
This switch selects the mode of operation. Operation for running code, programming for connecting to the LaunchPad.
Connection to LaunchPad, the
following pins MUST be connected
to Vcc, GND, TST and RST on the
LaunchPad. Please ensure that
the SampleBot is OFF and
Programming is selected.
