From arg , Mario Sacco brings us this interesting article on control of DC motors by setting "H-Bridge." Well known and
famous "H bridge" or "H bridge" is always the solution in systems where the rotation is an operational necessity. However, the real, physical world presents countless difficulties in operating the H-bridge Starting with the inertia of the mechanical system, through the speed response and ending in the braking process and appropriate detention, we find most of the problems that have been leaving many enthusiasts who are new to the world of robotics and mechatronics. Let us together a bit of theory and practice of this device to move the motors in our future productions.
With this circuit you can control DC motors by injecting a signal PWM can generate with a microcontroller.
The project underlying the control load by H bridge built around MOSFETs. Its implementation is simple and author provides full material: schematic, parts list, PCB files.
