D1-D4: Diodes provide a safe path for the motor energy to be dispersed or returned to the battery when the motor is commanded to coast or stop. In the lamp circuit, the protection diode is not needed, since there's no way for the polarity to get reversed in this circuit: Schematic view When the motor is replaced Maximum drive current is 120 MA per output. I think raising it might help.

Motor Driver Circuit Using Transistor
Before reaching 4000V, other parts such as wires and connectors will likely short out first. Could I use these parts instead of the ones in the tutorial??

- Sparkfun Relay Board Schematic The snubber diode backwards across the relay coil absorbs the reverse voltage inductive spike that occurs when turning off the coil (i.e., V=Ldi/dt).
- X10 power line control signals are sensitive to distance and noise and will not cross over from one power phase to the other, just like home networking plug in devices.
It also includes PWM dimming hardware for each of the three driver circuits and it can generate 230 different colors and brightness levels. It has limited current drive, but it could be added to the input side of a driver circuit to provide optical isolation. An example library to control stepper motors is available in the cookbook. http://bestmatchcomputers.com/dc-motor/bldc-motor-controller-circuit-diagram.html Note that it also requires a driver circuit and the external wire connections are the same as the relay board.

Thanks for now.
Very good circuit. However, I do have a couple of questions: 1. An inline fuse and even a GFI breaker is not a bad idea. weblink
You could be right about the logic level MOSFETS, try it and let me know how it goes!
Thanks for such a good information about dc motor controller! :)
I'm planning to make
In this instructable, I'll demonstrate a simple and inexpensive circuit that controls a DC motor from two I/O pins. All of them should be available at your local RadioShack or hobby store. (1) DC motor (4) MOSFET transistors. I'm wondering what's the purpose of having an NPN turn on a PNP, turn on a MOSFET. For speakers, an audio amplifier IC is often used to drive the speaker.

They connect the motor to ground (negative terminal of the battery).

More advanced H-bridge circuits prevent this issue with a bit more decoding on the transistor inputs and add a dynamic brake feature. SSRs and TRIACs will be explained in a later section. A pwm signal should cary the speed of the motor. By connecting a resistor to either +VDC or GND, it turns on or off the corresponding transistor. (+VDC is the positive end of the battery.
A lower resistance would waste more power, but wouldn’t likely provide better performance for motors running on consumer batteries. A few SSRs use reed relays on the input signal or feed the input through a DC to AC converter with a transformer for electrical isolation. The 10K ohm resistors pull the bases of the transistors to ground when your I/O pin goes low, and the 2200 ohm resistors limit the current that can be drawn from
