Getting Started with the BrickPi

Contributors: Shawn Hymel

Programming

Open a terminal (if you do not already have one open) and create a new file for our motor and sensor test. Open that file with Leadpad (Raspbian's default text editor).

leafpad motor_sensor.py

Enter the following code into the text editor:

language:python
from BrickPi import *

BrickPiSetup()

BrickPi.SensorType[PORT_1] = TYPE_SENSOR_TOUCH
BrickPi.MotorEnable[PORT_A] = 1

BrickPiSetupSensors()

while True:
        result = BrickPiUpdateValues()
        if not result:
                if BrickPi.Sensor[PORT_1]:
                        BrickPi.MotorSpeed[PORT_A] = 200
                else:
                        BrickPi.MotorSpeed[PORT_A] = 0
        time.sleep(0.01)

Save and exit out of Leafpad. In the console, enter the following:

python motor_sensor.py

Now, whenever you press the Touch Sensor, the Servo Motor should move!

Press ctrl+c to end the program.
