Hi,

I have some problems with H bridge, hoping someone here could help me detect what's wrong or atleast give me some idea where to look.

Note that R3 and R8 are not connected because there was some error with them, so we just left them out. Our mentor said that It should not matter while we are testing it. If u need any more info I will gladly provide them.

Our mentor also gave us ir2110 instead of ir2112, which we orginally developed board for. Not sure why but nothing I can do about it now.


So back to the problem. I have tryed to control ir2110 using arduino and sending some signals to it. Main ideas was to send 5v signal to Input high while not sending anything to Input Low, then after a second doing opposite thing. But when I do that I always have voltage on BOTH output high and low, and it's constant, not changing. Therefore either transistors are always open.

I would need some help with this, if possible.

Thanks in advance.
