Bumble Pi Programming:

Enter the following code in Python IDLE and save the file with the name of SRC:

from Bluetooth import *
Including the libraries!!
import RPi.GPIO as GPIO

GPIO.setmode(GPIO.BCM)
GPIO.setwarnings(False) Addressing the GPIO Pins as per
GPIO.setup(16,GPIO.OUT) Pi Shield configuration

MotorL2=18
enA=20 Creating variables for motor
functionality
MotorR1=26
MotorR2=12
enB=19

GPIO.setup(MotorL1,GPIO.OUT)
GPIO.setup(MotorL2,GPIO.OUT)
GPIO.setup(enA,GPIO.OUT)

GPIO.setup(MotorR1,GPIO.OUT)
GPIO.setup(MotorR2,GPIO.OUT)
GPIO.setup(enB,GPIO.OUT) Initializing the output pins

GPIO.output(MotorL1,False)
GPIO.output(MotorL2,False)
GPIO.output(MotorR1,False)
GPIO.output(MotorR2,False)

p=GPIO.PWM(enA,1000)
