Connecting  Roli's  Motors              (H-Bridge)

Introduction
In this lesson, we will demonstrate how to connect the H-Bridge (motors) to your EZ-B v4 Smart Robot Controller.  The H-Bridge is a special type of IC (integrated circuit) that converts low voltage power from the EZ-B pins to the DC motors that drive the tracks. 

You will find H-Bridges in any device that uses DC Motors.  This is because Micro Controllers or Micro Processors (such as the EZ-B) cannot provide current to power DC motors directly.  The H-Bridge is located inside the body of Roli.  This lesson will connect the wiring harness from the H-Bridge to the EZ-B v4.

What You Will Need
​
  • An Assembled Roli with a charged battery
  • A Windows PC with ARC (formerly EZ-Builder) Installed

Step 1
Locate the H-Bridge wiring harness.
Step 2
Before we can connect the wires to the EZ-B, place your EZ-B into Roli.
Step 3
Connect the wiring harness to your EZ-B according to the following instructions.
D0 - Green (Left PWM)
D1 - Blue (Left Trigger A)
D2 - Purple (Left Trigger B)
D3 - Grey (Right Trigger A)
D4 - White (Right Trigger B)
D5 - Black (Right PWM)


Red & Black Wires
D0 Red Pin - Red Wire
D0 Black Pin - Black Wire

Connect the power from the EZ-B to the H-Bridge.  The power wires are the two Red & Black wires from the H-Bridge. They will connect to the matching Red and Black pins of the D0 Port. Consult the photo above to see how the Red and Black wires are connected to the matching Red and Black pins of the port D0 of the EZ-B. It is very important that the Red and Black wires are not connected in  reverse, or you could damage the robot.

Complete
You now know how to connect the H-Bridge and use its basic functions.  If you experience trouble getting Roli to move, you may need to check Roli's Internal H-Bridge wiring.
