Okay, thank you for your help and for being nice. I tried running the snippet below and it doesn't work the best either, it takes sometimes so long to print the new value (like 5 seconds). I connected the echo pin using a voltage divider with the values R1 = 1000 ohms, R2 = 2000 ohms to my rpi 4B.
Code:
#main.pyimport timeimport RPi.GPIO as GPIOdef main(): global last_distance GPIO.setmode(GPIO.BOARD) TRIG_PIN = 7 ECHO_PIN = 11 GPIO.setup(TRIG_PIN, GPIO.OUT) GPIO.setup(ECHO_PIN, GPIO.IN) pulse_start_time = 0 pulse_end_time = 0 while True: GPIO.output(TRIG_PIN, GPIO.LOW) time.sleep(2E-6) GPIO.output(TRIG_PIN, GPIO.HIGH) time.sleep(10E-6) GPIO.output(TRIG_PIN, GPIO.LOW) while GPIO.input(ECHO_PIN) == 0: pulse_start_time = time.time() while GPIO.input(ECHO_PIN) == 1: pulse_end_time = time.time() pulse_duration = pulse_end_time - pulse_start_time distance = round(pulse_duration * 17150, 2) if distance > 300 or distance <= 0: distance = last_distance else: last_distance = distance print(distance) time.sleep(1)main()Statistics: Posted by mart1nek — Thu Dec 21, 2023 11:46 pm
