Hi everyone,
I really want to know how to make a LED lit by using an ultrasonic sensor. I have watched several videos about that and it looks interesting but I am not quiet sure how it really works and how to connect them. Thanks!
Welcome to the forum
What exactly do you want to do ?
I suspect that you want to turn an LED on (or off) when an object is within (or beyond) a certain distance from the sensor. Am I correct ?
Which Arduino and sensor do you have ?

Did the videos have a tutorial link in the description?
- Learn to read the sensor.
- Save the reading as a variable.
- Learn to light a led.
- Learn to react to conditions, like lighting a led according to a variable value.
- Learn that your original question divided into two tasks that could be solved completely independent on each other. Lighting a led according to a variable value is completely independent on what sensor you have.
