HBRIDGE Dual Channel H-Bridge Motor Driver Shield
Posted: Sat Mar 21, 2015 5:47 am
Hi All.
So I have mounted my new HBRIDGE Dual Channel H-Bridge Motor Driver Shield to a Freetronics eleven as per the quick start guide. Also loaded the code (copy and paste) from the quick start guide - Freetronics HBRIDGE Motor Driver Shield Quickstart Guide - Controlling A 2-Wire DC Motor.
But no responce from the motor.
The motor looks exactly the same as the one in the quick start pic.
Jumped the motor across motor power pins +ve and -ve on the sheild = check motor is working - all good.
Run blink test on the eleven - all good.
- turns out I bought two H Bridge sheilds at the time; so I swap sheilds run same set up process and test senarios on the second sheild - alas... No joy.
-- probably something simple and obvious... but I can not see it. Can anyone help out please?
thankyou
