User Manual

For C language users:

Step 2: Get into the folder of the code

cd /home/pi/SunFounder_Super_Kit_V3.0_for_Raspberry_Pi/C

Step 3: Compile

make 11_motor

Step 4: Run the executable file above.

sudo ./11_motor

Code Explanation

digitalWrite(MotorEnable, HIGH): // Enable the L239D

digitalWrite(MotorPin1, HIGH):) // Set a high level for 2A(pin 7); since 1,2EN(pin 1) is

in high level, 2Y will output high level

digitalWrite(MotorPin2, LOW): // Set a low level for 1A, then 1Y will output low level,

and the motor will rotate.

for(i=0;i<3;i++){

delay(1000);

} // this loop is to delay for 3*1000ms

digitalWrite(MotorEnable, LOW) // If 1,2EN (pin1) is in low level, L293D does not work.

Motor stops rotating.

digitalWrite(MotorPin1, LOW)

digitalWrite(MotorPin2, HIGH) // Reverse the current flow of the motor, then the motor

will rotate reversely.

For Python users:

Step 2: Get into the folder of the code

cd /home/pi/SunFounder_Super_Kit_V3.0_for_Raspberry_Pi/Python

Step 3: Run

sudo python 11_motor.py

Code Explanation

GPIO.setup(MotorPin1, GPIO.OUT) # Set pin1 and pin2 for motor’s rotation direction

as output pin

GPIO.setup(MotorPin2, GPIO.OUT)

GPIO.setup(MotorEnable, GPIO.OUT) # Set pins for motor’s working condition as

output pin

GPIO.output(MotorEnable, GPIO.LOW) # Set the motor low level for initial state

GPIO.output(MotorEnable, GPIO.HIGH) # Set the motor in high level

GPIO.output(MotorPin1, GPIO.HIGH) # Set pin1 in high level and pin2 in low level
