[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?

You can use PWM to control the speed of a motor, the brightness of a LED, or to generate analog waveforms. [Jack] shows how to set up the processor to do locked anti-phase PWM to drive the wheels ...

The motor driver's integrated H-bridge circuitry and support for PWM enable precise speed and direction control, making it an ideal choice for applications demanding high precision and efficiency.
