Bitbeam - Shaft Encoder Wheel
Description
Bitbeam Is A 3D Printable, Lego Technic-Compatible Construction System. More Info At Http://Bitbeam.Org Use This Shaft Encoder Wheel To Measure The Rotation Of A Wheel. (You'Ll Also Need An Led And A Phototransistor.) Shaft Encoders Are Especially Useful When Using A Dc Motor For Motion. Dc Motors Are Cheap And Wonderful For Making Little Robots Move, But Dc Motors Do Not Come With A Built-In Feedback Mechanism For Precision Control. Shaft Encoders Are A Great Way To Get That Feedback. For An Explanation On How To Use Shaft Encoders In Your Projects, I Recommend Fred Martin'S Book ["Robotic Explorations"](Https://Www.Amazon.Com/Dp/0130895687/Ref=Cm_Sw_Su_Dp).
