There’s a great demonstration of the circuit braking a fast spinning motor in the video clip below the fold. It is possible to use this driver with PWM, but [JM] has some warnings about inbuilt ...

[Jana Marie] must agree with this sentiment, one of her latest projects involves building a tool to generate a PWM signal and test servos using an Attiny25/45/85. What tools have you build recently?

Compared to the Uno, the Mega also comes complete with 15 PWM pins, which is handy for controlling ... For instance, to set a motor connected to D11 to only 25% speed, the function should be ...
