Arduino l293d datasheet

The enable/disable function of the motor control is signalled by Arduino Digital Pin 4 and 7. Roboduino Motor Shield uses PWM output Pin 6 and 9 and Digital Pin 7 and 8. The motor shield is powered directly from Arduino. It is strongly advised that use external power supply (on Arduino) to power the Arduino instead of the USB power supply.

Neste tutorial vamos mostrar como utilizar o L293D para controlar motores de corrente contínua (DC) com Arduino. O L293D é basicamente uma ponte-H em um circuito integrado. Pode-se controlar motores de até 36V de alimentação como mostra no datasheet. Cuidado, que o L293D aguenta corrente constante de 600mA e corrente pico em torno de 1.2A. The Adafruit Motor Shield kit is a great motor controller for Arduino, but it does a little care to make sure it's used correctly. Please read through all the User manual sections at left,

The Arduino Motor Shield is based on the L298 , which is a dual full-bridge driver designed to drive inductive loads such as relays, solenoids, DC and stepping motors. It lets you drive two DC motors with your Arduino board, controlling the speed and direction of each one independently. CONNECTIONS IN L293D. Pin1 and Pin9 are “Enable” pins or the switch pins as you can say. They should be connected to +5V for the drivers to function (for the motor to follow the inputs). If they pulled low (GND), then the outputs will be turned off regardless of the input states, stopping the motors.

The L293D datasheet specifies that this device is a monolithic integrated high voltage, high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays solenoides, DC and stepping motors) and switching power transistors. (if you use Diecimila Arduino, don’t forget to set Arduino power jumper to USB). If you want to use 2 separate DC powers for Arduino and motor, plug in the power supply to DC barrel of Arduino, and connect the other power supply to PWR_EXT on the motor shield. Remove the power jumper on the motor shield. El Shield Motor Driver L293D fue diseñado por Adafruit para facilitar el control de motores con Arduino. El shield facilita el control de hasta 4 motores DC o 2 motores paso a paso unipolares o bipolares y 2 servomotores pequeños (SG90 o MG90). Arduino Motor Control con ponte-H L293D o SN754410 Arduino Ponte-H per controllare un motore nei due sensi di marcia Salve a tutti ragazzi, come già detto nel titolo oggi faremo ruotare un motore nei due sensi di marcia.
