I've made my 50$ robot, and I am now trying to program it. I've been messing around with the light sensors I made and Arduino and servos and such, and i know how to make it that a different amount of light will turn the servo at different speeds. The problem is, I don't think its sensitive enough. It goes one speed in the light, but to make it slow down/stop, I have to entirely cover the sensor in my hand.
How can I make it more sensitive?
Before I modified the servo i tested the same thing, and by waving the sensor around the motor would twitch to different positions. So it does work, unless I screwed up on the modifying.
Another thing, I was reading through this post http://www.societyofrobots.com/robotforum/index.php?topic=2724.0
and saw the numbers 23/.992*(time in milliseconds) = number of cycles . Where does the 23 and the .992 come from??? Would it be different for an Arduino?
