L298 MOTOR DRIVER BOARD

L298 Motor Driver Module is a high-power motor driver perfect for driving DC Motors and Stepper Motors. It uses the popular £298 motor driver IC and has the onboard 5V regulator which it can supply to an external circuit. It can control up to 4 DC motors, or 2 DC motors with directional and speed control

This motor driver is perfect for robotics and mechatronics projects and perfect for controlling motors from microcontrollers like Arduino, switches, relays, etc. Perfect for driving OC and Stepper motors for micromouse, line-following robots, robot arms, etc

An H-Bridge is a circuit that can drive a current in either polarity and be controlled by Pulse Width Modulation (PWM).

Working:

Pulse Width Modulation is controlling the duration of an electronic pulse. In matars try to imagine the brush as a water wheel and electrons as the flowing droplets of water. The voltage would be the water flowing over the wheel at a constant rate the more water flowing the higher the voltage. 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. Thus PWM. Take the water wheel analogy and think of the wains hitting it in pulses but at a constant flow. The longer the pulses the faster the wheel will tum, the shorter the pulses, the slower the water wheel will fum Motors will last much longer and be more reliable controlled through PWM
