L293D Primarily based Arduino Motor Protect

L293D Motor Driver Shield for Arduino is probably one of the most versatile Motor Driver Shield in the market and features 2 servo and 4 motor connectors for DC or stepper motors. That makes it a great shield for any robotic project.This Arduino compatible motor Driver shield is a full-featured product that it can be used to drive 4 DC motors or two 4-wire steppers and two 5v servos. It drives the DC motor and stepper with the L293D, and it drives the servo with Arduino pin9 and pin10.L293D is a monolithic integrated, high voltage, high current, 4-channel driver. Basically, this means using this chip you can use DC motors and power supplies of up to 36 Volts, that some pretty big motors and the chip can supply a maximum current of 600mA per channel, the L293D chip is also what’s known as a type of H-Bridge.

The H-Bridge is typically an electrical circuit that enables a voltage to be applied across a load in either direction to an output, e.g. a motor.The shield contains two L293D motor drivers and one 74HC595 shift register. The shift register expands 3 pins of the Arduino to 8 pins to control the direction of the motor drivers. The output enables the L293D is directly connected to PWM outputs of the Arduino

L293D defend is a driver board primarily based on L293 IC, which may drive 4 DC motors and a couple of stepper or Servo motors on the similar time. Every channel of this module has a most present of 1.2A and would not work if the voltage is greater than 25v or lower than 4.5v. The Arduino Motor Protect is predicated on the L298 (datasheet), which is a twin full-bridge driver designed to drive inductive hundreds comparable to relays, solenoids, DC, and stepping motors. It enables you to drive two DC motors together with your Arduino board, controlling the velocity and route of every one independently.

To make use of this, join 5V to Allow 1, Vss, and Vs on the L293D. Join digital output pins (we’re utilizing 6 and seven) to enter 1 and enter 2 on the L293D. Join your Arduino’s GND to each GND pins on the identical aspect of the L293D. Lastly, join output 1 and output 2 of the L293D to your motor pins. To check the L293D motor driver defend, begin by plugging the defend on the highest of the Arduino. Subsequent, join the facility provide to the motors. Now join DC motors having voltages between 4.5 to 25V to the defend. Lastly, join the exterior 9V energy provide to the EXT_PWR terminal. The L298 helps larger currents (as much as 4 A with correct warmth sink), the L293D is restricted to 600 mA. the L298 has a better working voltage (as much as 46 V), the L293D is restricted to 36 V. the L298 is a twin full-bridge driver whereas the L293D is a quadruple half-bridge driver.
