Get rid of that old tennis ball hanging from a string in your garage and replace it with a simple to build and use LED parking indicator. Four different approach and parking zones, each with their own LED color, guide the driver to the optimal parking position. Different effects can be selected that use the LEDs to provide a 'countdown' to the final parking spot. In addition, a 'backup zone' will flash the LEDs if the driver gets too close to the sensor or overshoots the parking zone by a user-defined distance.
All options and settings are controlled via a simple web app with over-the-air updates. The system also has optional MQTT if you want to integrate into Home Assistant or other platform to provide vehicle detection or to create automations based on the data. Can your tennis ball do all that?
Note: There is an error in the video when reporting the minimum distance, in inches, of the VL53L0X. 50 mm is correct, but this is approximately 2" and not the 0.2" shown.
You can find a written version of this project with step-by-step build instructions, full parts list, wiring diagrams and more at:

Firmware and instructions for using the web application, including all options and settings, are located in this Github repo:
