Let's Make Robots!

another first robot question

Is it possible to use a servo with the darlington driver in?

the start here link tells you to take it out, but wouldn't it help keep down the noise that you get, especially with the SRF05?

IR or Ultrasound?

What is the difference(s) between ultrasonic sensors- such as the SRF04, 05 and 08, and the sharp IR sensors ?
