Jetson nano

1. Preparation

Connect the motor drive board and Jetson nano according to the wiring diagram, connect the battery to the power input interface on motor drive module.

Note: The motor interface wire sequence of the dual motor drive board should correspond to the motor pin! Otherwise, the motor drive plate will be damaged.

Note: The motor interface wire sequence of the dual motor drive board.

2. Code

​x
import RPi.GPIO as GPIO  #Import library
import time

GPIO.setmode(GPIO.BCM)  #Set pin
AIN1 = 17
AIN2 = 18
BIN1 = 22 
BIN2 = 23
GPIO.setwarnings(False)   #Remove warning
GPIO.setup(AIN1, GPIO.OUT)  #Set pin to output mode
GPIO.output(AIN1, 0)
GPIO.setup(AIN2, GPIO.OUT)
GPIO.output(AIN2, 0)
GPIO.setup(BIN1, GPIO.OUT)
GPIO.output(BIN1, 0)
GPIO.setup(BIN2, GPIO.OUT)
GPIO.output(BIN2, 0)

def forward():  #Motor rotation
    GPIO.output(AIN1,1)
    GPIO.output(AIN2,0)
    GPIO.output(BIN1,1)
    GPIO.output(BIN2,0)
    
def stop():   #Motor stop
    GPIO.output(AIN1,0)
    GPIO.output(AIN2,0)
    GPIO.output(BIN1,0)
    GPIO.output(BIN2,0)

forward()   #Motor rotation
time.sleep(5)   #Delay 5 seconds
stop()   #stop
GPIO.cleanup()  #clean up

3. Experimental result

Jetson nano runs the program. The motor drive board drives the motor to rotate, delaying for 5s, and then stops rotating.
