Hey everyone I made this ultrasonic range finder backup sensor to enter a contest for an iPad.
It gives you the distance to an object in feet then inches
Shows your position on a little graph
Has Green, Yellow, and Red color zone indicators
And alerts you with annoying high pitched tones!
Check it out and Like it on youtube to help me win!
Here is a wiring diagram and schematic I created in Fritzing. I have also attached the Fritzing file.
* I also just attached my sketch as well feel free to have a look at your own risk...
...but be nice I'm a newbie and was rushing to get this done in two days for the contest deadline!
