Arduino Ibt_2 H-bridge

Question

I'm curious if anyone has used the Arduino IBT_2 Motor Controller with EZBv4

It looks like I share the ground, can power the motors with my 6 vdc SLA bat attached to Vcc, attach R_EN and L_EN to each other and to 5.5v, then use RPWM and LPWM on digital out ports to control Fwd/Rvs movement of the motors.

Any experiences with any of this?

Thanks! Stephen

Pretty sure I found what I needed here: https://synthiam.com/Community/Questions/5664 RPWM High and LPWM Low to move forward RPWM Low and LPWM High to move in reverse R_EN and L_EN connected together and tied to 5.5V (High) to enable this R_IS and L_IS are optional current monitoring pins VCC = 6 to 27 VDC GND = shared ground

Have a read of this also to get a little more understanding of how the H-Bridge works.  I may be wrong but I believe this H-Bridge will only operate one motor. There's a bit more info on the controller here Also, have a read of teh datasheet

@Rich great to see you on here again! Welcome back man! ....Maybe you've always been here and I haven't been on enough. @Mayaway I have used those H-bridges successfully with the inMoov's wheel chair base. @Rich is correct, one of these H-bridges will operate only one motor. Enable lines can be 3.3V activated I believe (regular EZ-B digital I/O).

That's a nice little controller for a LOT of amps at a good price. Even needing 2 of them is still better price than the common high amp alternatives, Sabertooth, Roboclaw or Parrallax HB25. (of course, they take more ports, but still, a nice looking option). Alan

anybody else have a wheelchair ( scooter) base and these IBT-2's ? I would like to learn some coding and generally collaborate, like a good choice for a stepper motor controller for the waist action,

There hasn't been a lot of talk about using stepper motors with EZ Robot. I haven't really seen anyone showcase a way to do this or offer a controller that worked for them (unless I missed something which is totally possible eek ).

There's a thread somewhere where I made an example program for driving steppers with a L298 motor driver but I'd have to look it up.
