Hi Larry,

Thanks for posting this up. I’m still confused about how you got 65. I’m using a GP2D120 sensor and I’m trying to modify your code to that.
Please help.

Thanks,
ryder

Don’t average! Never average with sensors! Use filters like reading 10 times, sort it, and discard the extreme values. This is better than average.

Worked great for me, and the values aren’t much off (for my needs anyways), thanks a bunch!

in this statement
float distance = 65*pow(volts, -1.10);

how you calculte the -1.10.can you please explain it more

Yeah, I’m having the same problem. It is set at 9600 baud but nothing is printed in the main console. Also, the Serial Monitor keeps printing 0.
