L293D Motor Driver shield for Arduino

Description

The L293D Motor Driver/Stepper/Servo Shield Expansion Solder Pin Board provides a flexible and practical method for using an Arduino microcontroller to operate motors, stepper motors, and servos. This shield is made to work with Arduino boards, giving you a simple method to increase the ability of your projects to control motors.

The L293D Motor Driver/Servo Shield for Arduino has 4 motor connectors for DC or stepper motors and 2 servo connectors. As a result, it provides a great shield for any robotic project. This motor driver shield for Arduino is a fully functional device that can operate four motors, two  4-wire steppers, and two 5-volt servos. The L293D is used to operate the DC motor, stepper, and servo. The Arduino pins 9 and 10 are used to drive the servo.

One 74HC595 shift register and two L293D motor drivers are found on the shield. To regulate the direction of the motor drivers, the shift register increases the Arduino’s three pins to eight pins. The output enables the L293D to be linked directly to the Arduino’s PWM outputs.

Note: The 2-pin EXT-PWR terminal block or the Arduino board’s DC Jack (typically 9V) may be used to power the motors. Removing the PWR jumper will prevent harm to the shield and Arduino board if power is supplied through the EXT_PWR terminal block.

Features:

1. 2 connections for 5V ‘hobby’ servos connected to the Arduino’s high-resolution dedicated timer
2. 4 H-Bridges: L293D chipset provides 0.6A per bridge (1.2A peak) with thermal shutdown protection, and internal kickback protection diodes. Can run motors on 4.5VDC to 25VDC.
3. Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5% resolution)
4. Pull-down resistors keep motors disabled during power-up
5. Big terminal block connectors to quickly hook up wires (18-26AWG) and power
6. The Arduino reset button brought up top
