Hi guys this is my first tutorial, I’ve just started a few months ago learning electronics (previously I’ve just knew how to program in C and Python). When I finished this project (took me about 5 hours or something) I’ve decided to share to help anyone that is starting in electronics.
Basically we have an Ultrasonic sensor that measures the distance and the LED’s bar graph will light up according to our distance from the sensor and as we get closer the buzzer beeps in a different way. This circuit can work as a parking sensor! It’s easy and cheap.
Check out the YouTube video and the instructables for more detailed information.
The code it’s on instructables but you can download it here:
