DESCRIPTION

The PF-for-Arduino® brick is motor driver for LEGO® PF motors that can be controlled with an Arduino board. The top of the motor driver has a 4 pin PF connector. The driver is compatible with the following motors:

• Power functions M-motor
• Power functions L-motor
• Power functions XL-motor
• Power functions train motor
• Power functions servo motor

On the Arduino® side, the motor driver has a 20cm / 8" long cable with four 0.1" female pin connectors.

The base has 8 anti studs to connect the motor driver to your MOC.

DIMENSIONS

Brick: 2 studs wide, 4 studs long, 1 brick high
Cable: 20cm / 8"

INSTRUCTIONS

The PF-for-Arduino motor controller has a 4 wire cable. The brown and red wire provide power to the controller and motor. The orange and yellow wires carry the the control signals to actuate the motor.

Connect the brown cable to the ground and the red cable to the positive terminal of a 9V power source. Connect the orange and red cable to a PWM pin of your Arduino® board. The S1 input controls the PF wire C1, the S2 input control the PF wire C2. Use the following control values to actuate the motors.

S1	S2	Motor
HIGH	LOW	Turns CCW
LOW	HIGH	Turns CW
LOW	LOW	Stop

Use PWM to control the speed of the M, L, XL, and train motor or the angle of the servo motor. Respect the following voltage limits on the signal pins S1 and S2:

	Min.	Max.
LOW	0.0V	0.7V
HIGH	2.5V	9.0V
