BTS7960 H- Bridge solved with post #18213

[Moppi]

Hallo,

I like to Build 2 dof seatmover Unsinn the fantastic description by sironame.

Is it possible to use the BTS7960 h- brigde with arduino and x sim .

Im confused the BTS7960 Needs on more cable als Showmaster in sironames Tutorial.
Here the Description

Can someone help.

Thanks

Hi sironame,
Must i use this Bridge ?

Yes , l can you this brigde with arduino , it controls motors a bit diferent than other brigdes,let me try explain. l will suposed you know a bit programming at arduino ok ?

Look : you have vcc pin ( let it free), GND (Connect with arduino GND) , IS pins ( let it free, no connect) , l_EN AND E_EN ( connect it together amd take a arduino pin to control it , if enable or not the motor, l dont remenber now if it is active at low or high levels, you will have to test. And now, the most importants pins, L_PWM and R_PWM, this two pins wil control both speed and cw/ ccw rotation path. l ll explain :

With L_PWM = 0 and R_PWM = 255 motor will run full speed for cw, with L_pwm 255 and r_pwm =0 will have fill speed for ccw. with L_pwm= 127 and r_pwm = 0 will have half speed for ccw. did you understand ?

but, l probably wil not work with the default code f or arduino, cause it controls this diferent way .. you need to adapt the arduino code to make it work .

For people which do not know H-Bridges, and have no knowlege about wiring them, it is better to use a polollu interface which comes with a bridge mounted to the usb interface and which is more professional in handling.

You are right sironame,

But it is my First time using programmable mikrocontroller. Finde es spannend.

So i have to learn and i think the bought h- bridges are not so Bad
My budget is not so big

I have read about polollu it seems to easy and expensiv

Jedoch wenn ich mir noch 8 verschiedene Bridges kaufe ist polollu vielleicht günstiger

Lehrgeld learnmoney??

I am an newbie
