What is a L293D Arduino?

What is a L293D Arduino?

The L293D is a 16-pin Motor Driver IC which can control a set of two DC motors simultaneously in any direction. The L293D is designed to provide bidirectional drive currents of up to 600 mA (per channel) at voltages from 4.5 V to 36 V (at pin 8!). You can use it to control small dc motors – toy motors.

How does Arduino L293D control DC motor?

Step 2: Hardware Setup

  1. Connect 5V and ground of the IC to 5V and ground of Arduino.
  2. Connect the motor to pins 2 and 3 of the IC.
  3. Connect IN1 of the IC to pin 8 of Arduino.
  4. Connect IN2 of the IC to pin 9 of Arduino.
  5. Connect EN1 of IC to pin 2 of Arduino.
  6. Connect SENS A pin of IC to the ground.

Can you drive a DC motor connecting directly with digital IC output pin?

One H-bridge is capable to drive a dc motor in bidirectional. L293D IC is a current enhancing IC as the output from the sensor is not able to drive motors itself so L293D is used for this purpose.

What is L293D used for?

The L293D is designed to provide bidirectional drive currents of up to 600-mA at voltages from 4.5 V to 36 V. Both devices are designed to drive inductive loads such as relays, solenoids, DC and bipolar stepping motors, as well as other high current / high voltage loads in positive supply applications.

How does a L293D work?

The L293D IC receives signals from the microprocessor and transmits the relative signal to the motors. It has two voltage pins, one of which is used to draw current for the working of the L293D and the other is used to apply voltage to the motors.

How Arduino code controls DC motor speed?

Arduino Motor Control Setup

  1. Connect 5V and ground of the IC to 5V and ground of Arduino.
  2. Connect the motor to pins 2 and 3 of the IC.
  3. Connect IN1 of the IC to pin 8 of Arduino.
  4. Connect IN2 of the IC to pin 9 of Arduino.
  5. Connect EN1 of IC to pin 2 of Arduino.
  6. Connect SENS A pin of IC to the ground.

What happens when en1 pin of L293D is enabled?

L293D IC Pin Out There are 4 INPUT pins, 4 OUTPUT pins and 2 ENABLE pin for each motor. Pin 1: When Enable1/2 is HIGH, Left part of IC will work, i.e motor connected with pin 3 and pin 6 will rotate. Pin 2: Input 1, when this pin is HIGH the current will flow though output 1.

What are the main parts of DC motor?

These components are: a stator, a rotor, a yoke, poles, armature windings, field windings, commutator, and brushes. Many of its parts are the same as parts of AC motor, but with a little change.

What is the principle of DC motor?

The basic working principle of the DC motor is that whenever a current carrying conductor places in the magnetic field, it experiences a mechanical force. Fleming’s left-hand rule and its magnitude decide the direction of this force.

What is the difference between L293D and L298?

L293 is a quadruple motor driver that uses a half-H driver while L298 is a dual full-H driver, i.e, in L293 all four input-output lines are independent while in L298, a half-H driver cannot be used independently, only a full H driver has to be used.

How to control DC motors with an Arduino and an l293d?

There are lots of ways to control DC motors with an Arduino. But one of the easiest and most popular is with an L293D motor driver. The L293D motor driver is designed specifically to control DC motors, stepper motors, solenoids, and any other load with a high impedance.

What can the l293d motor driver be used for?

The L293D is a 16-pin Motor Driver IC which can control a set of two DC motors simultaneously in any direction. The L293D is designed to provide bidirectional drive currents of up to 600 mA (per channel) at voltages from 4.5 V to 36 V (at pin 8!). You can use it to control small dc motors – toy motors. Sometimes it can be extremely hot.

What is maximum current of Arduino l293d driver shield?

L293D shield is a driver board based on L293 IC, which can drive 4 DC motors and 2 stepper or Servo motors at the same time. Each channel of this module has the maximum current of 1.2A and doesn’t work if the voltage is more than 25v or less than 4.5v. So be careful with choosing the proper motor according to its nominal voltage and current.

How many pins does the l293d IC have?

It has two voltage pins, one of which is used to draw current for the working of the L293D and the other is used to apply voltage to the motors. The L293D switches it output signal according to the input received from the microprocessor. The L293D is a 16 pin IC, with eight pins, on each side, dedicated to the controlling of a motor.
