Hi all, just wanted to check if the following is correct behaviour for the LED. I'm also not getting anything above '0' from the ultrasonic sensor. My suspicion is that the 'Red' mode connection is bad, which also prevents feedback from ultrasonic.
Thanks!

The LED and the ultrasonic module are connected in parallel, you cannot use them at the same time.
However, you can use the LED module as the indicator for ultrasonic sensor.
Another way, you can use them independently by time division method.
