In a simple DC motor there are two main components, the вЂњstatorвЂќ and the вЂњarmatureвЂќ. Today weвЂ™ll examine a very common H-Bridge module based around the L298N integrated circuit.

An вЂњH-BridgeвЂќ is an arrangement of transistors that allow you to control both the direction and speed of the motor. A single transistor can be used to drive a DC motor, this works well providing you do not need to change the direction that the motor is spinning.ДЄ more versatile way of controlling a DC motor is to use a circuit called an вЂњH-BridgeвЂќ.

There are a number of ways to drive a DC motor from the output of your computing device. It is necessary to use some external electronics to drive and control the motor, and youвЂ™ll probably need a separate power supply as well. DC motors have current and voltage requirements that are beyond the capabilities of your microcontroller or microcomputer. Unlike LEDвЂ™s you canвЂ™t just connect a DC motor to one of the output pins of your Arduino or Raspberry Pi and expect it to work. They are inexpensive and are ideal for use in your Robotics, Quadcopter, and Internet of Things projects. Today DC motors range from huge models used in industrial equipment to tiny devices that can fit in the palm of your hand. Since then DC motors have been part of countless pieces of equipment and machinery. Specifications Of L298 Motor Driver H Bridge Module:Д«est Online Shopping website for motor Driver Module L298N For Arduino Dual H Bridge Motor Driver at a cheap price in Karachi Lahore Islamabad Rawalpindi Peshawar Multan Faisalabad Sukkur Quetta and all over Pakistan.The first practical DC (Direct Current) motor was invented by the British scientist William Sturgeon in 1832. Features Of L298N Dual H Bridge Motor Driver: Motors will last much longer and be more reliable if controlled through PWM. The longer the pulses the faster the wheel will turn, the shorter the pulses, the slower the water wheel will turn. Take the water wheel analogy and think of the water hitting it in pulses but at a constant flow. Motors are rated at certain voltages and can be damaged if the voltage is applied too heavily or if it is dropped quickly to slow the motor down. The voltage would be the water flowing over the wheel at a constant rate, the more water flowing the higher the voltage. In motors try to imagine the brush as a water wheel and electrons as the flowing droplets of water. Pulse Width Modulation is a means of controlling the duration of an electronic pulse. An H-Bridge is a circuit that can drive a current in either polarity and be controlled by Pulse Width Modulation (PWM). Perfect for driving DCВ for micro mouse, line-following robots, robot arms, etc. This Motor Driver is perfect for robotics and mechatronics projects and perfect for controlling motors from microcontrollers, switches, relays, etc. It can control up to 4 DC motors, or 2 DC motors with directional and speed control. H Bridge Driver Module uses the popular L298 motor driver IC and has the onboard 5V regulator which it can supply to an external circuit. This L298N Based Motor Driver Module is a high power motor driver perfect for driving DC Motors.
