Hello everyone! I can't seem to figure out why I can't get my Arduino's onboard LED to light up when an object is detected by one of my 5 ultrasonic sensors. It should trigger the LED high when an object is 59cm away or less in any of my sensors. The wiring is good, and the serial monitor displays…
