H Bridge

Question

Hey everyone,

I have been trying to get my H bridge to move both of my 12 Volt DC motors. They moved a little bit at one point with the control Movement Panel and a script and when I test them directly to the 12v battery they work 100% fine. But recently they just have stopped working all together. I believe they are 1.3 amps a piece and I am not sure if its just the H Bridge I am using or not. I have attached pictures below of the H Bridge, EZB, and my Ports.

I am VERY confused and have tried many options already and still nothing has changed that much.

Any help or advice is much appreciated!

Thanks in Advance,

Cameron

Check the switch to see if it's the wrong way. Also, did you press the ? (question mark) on the hbridge control? It will bring you to a tutorial page with diagrams and complete tutorial. Here's a shortcut link to the manual for the HBridge control: https://synthiam.com/Tutorials/Help.aspx?id=192 Also - what's the +5 volt wire connected to? That's an output +5. It should not be connected to a battery power source or that hbridge is broken. There's a good chance of damaging the I/O for those ports on the ezb if VCC is powering the hbridge's +5 output. The above manual link provides details. Don't forget the question mark buttons

@DJ Yeah I have triple checked my wiring and the 5v is connected to the EZB power plug in

Oh no - that's bad bad bad if the +5 is connected to the EZB power! I edited my previous post, reread please Check the manual please

Here is what the H Bridge is connnecting to: (just the 5V wire)

Please check the manual from the link above. Also reread my first response regarding the +5. Using that wire will damage the hbridge and most likely the ezb. The manual shows you how to connect everything. Please check the manual. I provided the link above. You can also access the manual by pressing the question mark on the hbridge control. The hbridge is most likely damaged due to using the +5 wire connected to vcc

@DJ thank you very much. I guess I messed up. But it did work before just fine no issues. I tested one of the ports that the h bridge was connected to and it worked just fine. So im good there. I will get the same H Bridge you have in the EZ store. Thanks again.

@DJ Sures I got EZ Robot 2.5 Amp motor controller and I did test the pins and they do read in fact 12v which is the exact voltage my battery is and I hooked it up and triple checked and the motors still wont move. the small led's on the motor controller are all red and when I check the voltage for the motor distribution wires they dont show voltage at all. I was thinking they are drawing too many amps? I have tried many times to find the problem and still no luck. Any help is appreciated thanks. Cameron
