Hi,
I would like to use 2 motors windscreen wiper. Amp of these motors is important, i bouhgt this H bridge :
My questions are :
- how to connect this H bridge on my EZ Board ?
- what's R_IS and L_IS ?
- what's R_EN and L_EN ?
And on ARC, which control can I use ?
Thanks for your answers.
Jerome
Did you tried what you found?
Don't know why I'm looking at this anyway here is the circuit diagram you need a common ground as Rich said between the EZ-B and the H Bridge. Do you really need a 43 amp controller for a wiper motor? as your diagram shows you'll need 2 controllers for 2 motors a L298N controller might be a simpler setup.
Wiper motors can draw a good 5 amps so l298n may not be a fit. Maybe a 2 x 5 but a sabertooth 2 x12 would be spot on. On this h bridge you have been using its instructions claim you only need 4 wires. 5v enable, ground, pwm1 , pwm2 then the supply voltage pos and ground as well. The problem with some no name equipment is getting it ton work and help to get it working.
I was able to look into the data sheet, it is very similar to the l298n. The instruction saying only 4 wires needed is misleading to a beginner. I went and purchase it, due to curiosity, connected as my diagram in the previous post and it work just fine. You can save youself a port by combining pwm1 and pwm2 into one wire ( 2 inputs, 1 output).
As @jstarne1 mention, when buying hardwares, it's best to purchase the one recommended in the tutorials, easier to use, well common among the community, already been tested, and we can help you.
PJ, I think your post was pretty much the same as mine but with different port numbers used, is that right? I just like to know if I figure things out correctly or not
Yes @rich your post was right on the money, I only did the graphical image so he can see it better, only the port were different. And I even purchase it just to see if I was right, and everything went smoothly. The diagram he posted seem a bit peculiar to me, doesn't make sense.
As a matter of fact, I think I'm going to gather as much H-bridges as I can and do a google sketchup image with them (tutorial) . I notice after Scripting H-bridge seem to be the most ask question.
@jstarne1 Sabertooth is the best route to go, L298n on the budget side.......I learned when dealing with robotic, Don't be cheap, otherwise you will pay for it later .
