Ultrasonic Parking Assist - Arduino Nano

thingiverse

This is a full project for a parking assist device based on an Arduino Nano. When mounted on a garage wall, it measures the distance to the vehicle and a LED strip displays green, amber, and red lights indicating the position. When it gets close to the desired park position the LED strip goes all red. The download includes the STL for an enclosure to hold the ultrasonic module and Nano which are soldered to a 70mm x 30mm protoboard. The download also includes the schematic and Arduino code. A printable cover for the LED strip can be fount at https://www.thingiverse.com/thing:4819400 I used a LED strip of 65 LEDs (about 4 feet). I used this one: https://www.amazon.com/gp/product/B07R6LR7DK/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 The number of LEDs, and distance parameters, are settable in the code. Mount the ultrasonic enclosure on the wall facing the incoming vehicle and at grill height. The LED strip can go anywhere. The LED strip will go out after about 20 seconds after no more movement is detected. The ultrasonics will then checks ever second to see if there is forward movement, and re-lights the LED strip if there is.
