Hi,

I was wondering I someone had a servomotor to recommand for using it with the Arduino ? Are there any that would simply work with the PWM outpins ? I am looking for an inexpansive one. :)

thanks !!

The easiest ones to use are those designed for radio-controlled airplanes and cars. they have the driver electronics built in, so all you have to do is connect three pins to them: +5V, Gnd and the PWM signal form the Arduino.

The regulator on the Arduino board will power one motor comfortably-- for more than that you will have to build an external power supply with a 7805 regulator.

Here is an example of the R/C variety of servo motors,and here is a page explaining how they work. The cost is usually about $15CAD/12USD/10Euros.. or thereabouts. Look for them in a local hobby store.
