Garage parking assistant

This is a device that helps to park the car in the garage at the right distance.

The idea is to give different signals when the car approaches a certain distance. It uses Arduino, an ultrasonic distance sensor, an addressable LED strip and a speaker. The device is installed at the end of the garage at bumper level.

* When the distance from the sensor to the car exceeds 1 meter (or whatever you cinfigure), it is considered that there is no car, the device is in standby mode. There is no sound signal, a running blue light is displayed on the LED strip (to let you know that the device is on and ready to go).
* When a car approaches, the LED strip lights up. As it gets closer, more LEDs light up, and the color smoothly changes from green to orange. An audible signal is also played, the duration depends on the distance.
* When the car approaches closer than the threshold distance (let's say 15 centimeters), the color of the tape changes to red and the tone of the sound also changes.
