Arduino UNO/Duemilanove 2dof firmware

[dualin]

Hi, Thanks for your great job. I've installed an arduino with this firmware in my sim and connected with a tronic dual h-bridge, it has worked a few hours and then the bridge had broken again. Then I'm looking to buy a new ones, what do you think about this H-bridge?

Will works fine with arduino?

How must I connect with my arduino??

Thanks in advance and sorry for my poor english.

Best regards

Unfortunately you cannot directly connect this driver to Arduino. This driver is "full-bridge" (based on two H-bridge drivers)

But you can use simple addition schematic with only one chip 74LS08 like this:

Thanks a lot Ale. Can you explain me a little more the connections???. I can't understand your schematic. I know only a little about electronic.

Thanks in advance

Hi Alex,

Thank you very much . I've tested successfully, maybe weekend I will finish my sim ...

Now, I will show a short video about my project,

Hi, tomorrow will arrive the H-bridges, and I've the 74ls02. Can you explain me the connections, please???

Thanks in advance

Hopefully thats all correct and to ask another question can we uses pins on the other side to run the second H bridge or do you recommend building a second card to run the other unit.

Hi, Robbie!
I think you can use one chip 74hc08 for controlling TWO Bridges from ONE controller (like Arduino).
But you have check the accuracy of Ground wires connect from power supplies.

Ale.
