Tell us about yourself!
Timothy,My initial reaction to your comment was, "why so negative"? But then i thought, this is the essence of engineering. You provided valuable questions and pointed out possible pitfalls without belittling. This is what drives incredible innovation and I for one thank you.
Why not mount the sensor on the front of the car and place the LED box on the dashboard? You could then use the car to power it and it would be a parking assistant anywhere.

You could then use the car to power it and it would be a parking assistant anywhere.I would also explore using an ATTiny but I think the number of LEDs may be a problem. To solve that perhaps use just one green and one red LED.The green one should flash at an increasing rate as you approach the flat surface finally light steady green and light the red one if you go too far.I love this project and thanks for sharing.

JoeE40, you may have misunderstood my comment. I am not criticizing Truffula or anyone else for that matter, to sell her wares. My point is simple that this is not the forum. Thank you for your thoughts.
Dear Truffula,Mikey77 was kind enough to share a wealth of knowledge for free but you chose to use this forum to sell yours. Why?
