I always thought the output of 7805 needed a capacitor as well? Anyway I would repace the IR2110 with something easier to use like UCC27322.

You are using just a regular motor right? Not a stepper motor? An oscilloscope will be a great tool to have here to see the pulses at each output.

To be honest, it's easier for me to look at a schematic, try to understand what is going on and then rebuild it as to how I understood it. Takes a little longer but I learn a lot more by thinking about it rather than just putting stuff together and hoping it works.
