Re: Ultrasonic Sensor Code Not Working

Karimimanawir This set up and code will work for any pi with a 40pin gpio. https://i.imgur.com/XkBIWqY.jpg Edit.... Just to make things clear R1K =1K resistor, R2K = 2K resistor. import time import RPi.GPIO as GPIO # Use BCM GPIO references # instead of physical pin numbers GPIO.setmode(GPIO.BCM) G...
