LEDs

Use the following commands to verify that each LED turns on and off correctly.

echo 1 > /dev/rtled0
echo 0 > /dev/rtled0

echo 1 > /dev/rtled1
echo 0 > /dev/rtled1

echo 1 > /dev/rtled2
echo 0 > /dev/rtled2

echo 1 > /dev/rtled3
echo 0 > /dev/rtled3

Switches

Press and release each switch while running the following commands.

cat /dev/rtswitch0
cat /dev/rtswitch1
cat /dev/rtswitch2
cat /dev/rtswitch3

Buzzer

Use the following commands to verify that the buzzer sounds correctly.

echo 440 > /dev/rtbuzzer0
echo 0 > /dev/rtbuzzer0

Distance Sensors

Place an object near the distance sensor and then move it away while running the following command.

cat /dev/rtlightsensor0

Motors

First, turn the motor power switch ON.

Use the following commands to verify that the wheels rotate correctly.

echo 1 > /dev/rtmotoren0

echo 400 > /dev/rtmotor_raw_l0
echo -400 > /dev/rtmotor_raw_l0
echo 0 > /dev/rtmotor_raw_l0

echo 400 > /dev/rtmotor_raw_r0
echo -400 > /dev/rtmotor_raw_r0
echo 0 > /dev/rtmotor_raw_r0

echo 0 > /dev/rtmotoren0

When finished, turn the motor power switch OFF.
