Control DC Motor Using L293D: Hello everyone,In this instructable we will be controlling DC motor using L293D and Arduino.The L293D motor driver is able to control the speed as well as direction of motor. PWM – For controlling speed: PWM is a technique where average value of the input voltage is adjusted by sending a series of On/OFF pulses, the average voltage is proportional to the width of the pulses known as Duty Cycle.The higher the duty cycle, the greater the average voltage applied to the dc motor this lead to the highest speed. There are 3 wires connected to the arduino, 2 wires connected to the motor, and 1 wire connected to a battery. But due to high voltage and current requirement of DC motors, it cannot be interfaced directly with microcontrollers. Voici un guide rapide avec quelques information complémentaire (configuration du circuit intégré etc) des choses que j'ai apprissent tout au long de mes essais pour utiliser un L293D avec un Arduino. Make an H-Bridge circuit to drive motor or simply use L293d ic to drive the motor. Toutefois, voyez-vous une erreur dans la programmation?

The device is capable of controlling four DC motors in a single-direction format, where each is simply switched on or off, but MOSFET circuits seem to be the preference among makers for this. I got fed up with indecipherable pinout diagrams within datasheets, so have designed my own that I think gives more pertinent information. The shield offers a total of four H-Bridges and each H-bridge can deliver up to 600mA drive current to the dc motor. Here the simple DC motor speed control PWM circuit is constructed by using IC 555 and motor driver IC L293D. As the shield comes with two L293D motor driver chipsets, that means it can individually drive up to four DC motors making it ideal for building four-wheel robot platforms.
