Triggering a motor at a certain sensor reading

prestonaltree

Hey, I'm a rookie and was just wondering if anybody could help me with the programming for a light triggered servo. When the photoresistor reaches a number, let's just say 55, it causes the motor to spin. I cannot figure out how to use the if then else etc. commands to make this work in the programming... HELP

When you're a rookie, the best way to learn is to work through the introductory tutorial manuals. You should download copies of "What's a Microcontroller?" and "Robotics with the BoeBot" which has a chapter on the use of photoresistors. Go to the main Parallax webpage, select the Resources tab, then click Downloads, then Stamps in Class Downloads. All of these have schematics and sample code.

You should also look at the Nuts and Volts Columns and the other tutorials. From the Resources tab, choose Nuts and Volts Columns.

Thanks! I have just finished reading "What's a Microcontroller" and will look into the boe-bot book
