### ⭐⭐⭐⭐⭐ 







  
  
    A Great Motor Controller
  

*by D***E on Reviewed in the United States on 26 May 2016*

I purchased this Pulse Width Modulator for my Robotics Team.  I wanted to teach them the circutry for driving DC Motors as that is the function of how DC Motors can be controlled in a robot.  This kit also allows the Students to operate a DC Motor without the need forcomputer software and hooking up to the control modules.  We had to add a switch to the output so we could control forward and reverseof the motors.  But all is all it was a successful product to purchase and was a great aide to the Students learning.  This Kit is very easy toassemble.  You need some soldering talent but if you go slow it will be a great tool for your hobby desk.
