Title: connecting sharp IR
Post by: Trumpkin on February 14, 2008, 01:06:54 PM

I am going to connect the Sharp IR Rangefinder to the $50 robot. the middle pin for the sensors on the $50 robot board is negative, right?

there are three pins on your rangefinder. when it is "looking" at you, the left pin is the signal out, the middle pin is a ground reference, and right is positive.

ok, thx. but what i really wanted to know is how to hook it up to the $50 robot board. i know the pin next to the chip is for signal wire, but i'm not sure what the other pins are, i am guessing that it is the same as the servos but i want to make sure.
