Dc motor driver circuit using transistors

Hello everyone, In this instructable we will be using transistor as a Motor Driver. Actually, We can't say it as a Motor Driver as it can just toggle motor ON or OFF rather than controlling the motor speed or direction. But, Using the transistor protects our Arduino from burning out. As ordinary DC motors runs on High Amps or consume more current than what an Arduino can Estimated Reading Time: 50 secs. This is a circuit for controlling an ordinary DC motor using a pair of transistors (1 NPN and 1 PNP). Note the dual supply of this circuit (+6V and -6V). A DC motor runs in one direction if the required voltage is applied across its winding and runs in the opposite direction if the polarity of the applied voltage is reversed. This function can easily be achieved by the circuit above. Using a Transistor to Drive a Motor. A general-purpose bipolar junction transistor (BJT) usually drives low-current miniature DC motors. For example, a BC transistor may drive small loads of up to 5 volts requiring less than mA. Miniature low-current motors employed in consumer electronics products move the focusing lens in digital cameras, or provide vibration alert in .

Using a Transistor to Drive a Motor. A general-purpose bipolar junction transistor (BJT) usually drives low-current miniature DC motors. For example, a BC transistor may drive small loads of up to 5 volts requiring less than mA. Miniature low-current motors employed in consumer electronics products move the focusing lens in digital cameras, or provide vibration alert in mobile phones, and even spin the CD in CD players. The transistors in the driver circuit are used to increase the current level of the incoming signals into an adequate value in order to drive control relays that are connected to the motor circuit.

As gasoline becomes more expensive, the environment more threatened and technological breakthroughs more common, electric cars are finally on the verge of becoming a viable alternative. Because production models, such as the Tesla Roadster. A DC to DC converter is also known as a DC-DC converter. Depending on the type, you may also see it referred to as either a linear or switching regulator. Here's a quick introduction. ​Driving DC Motors With Inputs Using the SparkFun Motor Driver: This is the thirteenth module in a series of lessons regarding applications and use of the Arduino This project is focused on the use of the SparkFun Motor Driver to drive.
