If these motors were part of a fully assembled vehicle, the effect of this sketch would be that the vehicle would be capable of avoiding hitting an object by slowing down on approach, until it came to a full stop.
A breadboard, electrical tape or solder to make solid connections in the circuit. A tutorial for using breadboards can be found below.
Note that: I’ve deleted the Automóvel-generated TIM2 initialization function and its parameter. Since our DC Motor library will handle that, we don’t need that function at all.
Figure 3: The changing resultant flux continually pulls the rotor magnet, causing the rotor to turn.
Connect the left pin of the potentiometer to the drain pin of the mosfet, the middle pin to the gate pin of the mosfet, and the right pin to the negative wire of the 9V battery clip.
Additionally, such gate drivers are not interchangeable. If they become discontinued, you’ll have to redesign the schematic together with the printed circuit board.

Is this sufficient? Perhaps it should come to complete stop a bit earlier, maybe at 5cm? Or perhaps, to be even more cautious, the vehicle should backup slightly away from the obstacle in order to provide room for a turns?
Integra’s BDC motor controllers for DIY robots. We used an H-bridge circuit for the controllers. As it was a discrete circuit, Integra’s engineers had to choose MCUs and gate drivers with separate semiconductor switches.
Do not cut off more than the plastic insulation so that the copper wire is exposed. Cutting more than the insulation will damage the wires ability to properly carry current and may prevent the circuit from working.
By regrouping the field coils the resistance in the field winding can be varied, which will give the required speed. This type of speed control is used for fan motors.
By decreasing the flux produced by the field winding, the speed can be increased and vice versa. Hence the name flux control method or field control method.
Applying current when the rotor position is unknown may cause the rotor to turn in the wrong direction. The use of sensors prevents this problem.
There will always be a moment when all the transistors are open. It may lead to voltage and power loss, or even short-out if the opposite upper and lower switches are in the on position.
