I&#8217;m also testing the pololu micro serial servo controller in the hope I could achieve better results. One good thing the pololu controller has, is the ability to set the speed of the movement, I guess it is [...]]]></description>

		<description><![CDATA[Here&#8217;s another way to hack a servo motor. This time Njay shows us how to do it, and it is quite easy. The code to use is the same for a normal servo, when you point it to the center (90 degrees) it will stop, than if you increment the angle it will start moving [...]]]></description>

		<description><![CDATA[Lusorobotica.com and EmbeddedDreams.com made a challenge to build a robot only with one servo, and this was what I came up with.
I used the sound sensor I&#8217;ve done a few days ago and a little paper-boat + a servo and a box and this is the result   :)

This how the puppet works:
