Hi, Dr._Rudy_Wells Have you got a common ground between the ezb and the regulator supply? As there are no photo's it would help to know which motor controller you are using and which pins were grounded to make it work.

All the best skidroe

hi skidroe

did uou puch in the small white button ?

for your second question,here's a video.

Here’s the manual for hbridge skill:https://synthiam.com/Docs/Skills/Movement-Panels/Dual-HBridge-w-PWM?id=16067

From the picture above it looks like the board already has an onboard 5V voltage regulator, so there may be no need for an external one. Check the chip to the left of the 12V input, probably a 7805 or equivalent. The +5V pins on that board are likely 5V out, not in.

Here's the application wiring that I found from the datasheet for that H-bridge.

Note that when you are using the H-Bridge with PWM, you do have to toggle the sliders on the skill's main window to enable the PWM. I'd advise to bring them up to 100% for testing and dial them back when things are working.

I will mark this resolved, but in actuality I have not gotten a chance to re-try this experiment
