    Hi there Ben, I noticed that the motors are humming and are choking at high power.

    I had the same problem with my project and I suspect that issue is the same.

    First I used analogWrite function and it worked well for small motors but the big ones were acting as yours do. So I included PWM.h library to my Arduino project, increased frequency of PWM signals (apparently bigger motors like higher frequency) and solved the problem.
