Using BASIC Stamp to control a car?

I have starter kit with BASIC Stamp 2 on Homework Board. Radio Shack didn't have the BOE-BOT robot kit in stock. Is it possible for me to use BASIC Stamp to control a model car? The car would have a motor for driving the wheels, a servo for steering, and some kind of touch sensors.

    Jeffrey,

    ·· You sure can use the Homework Board...You will need to either build or buy some sort of Motor Driver circuit for your project, but if you just bought the "What's A Microcontroller?" kit from Radio Shack, I would certainly go through all the projects in that first so you have a good understanding of how to connect to the BASIC Stamp.

    Is there a motor controller for the Homework Board? The book that came with the Radio Shack WAM Kit only has circuits and code for servo motors, not regular motors. What about the motors that came with the BOE-BOT Kit?

    Jeffrey,

    You can look at a number of off-the-shelf motor controllers which we sell, such as the ones from Pololu or Solutions Cubed. They generally take a serial input and manage the PWM to drive the motors. Or, you can make your own H-bridge. Take a look at Column 23 here, also: http://www.parallax.com/html_pages/downloads/nvcolumns/Nuts_Volts_Download_V1.asp

    Almost anything is possible depending on what you connect to a BASIC Stamp, but get through what you're doing first. This group can answer any question once you've dialed in the particular question.

    Yes. My students did it in robotics class. The speed control for the back wheels are controlled by the same signal that controls servo position. The steering also is controlled by servo control using pulseout comand. Add some IR or ultrasonic rangers and you are in bussiness.
