- The project designed around L293D IC. The L293D device is quadruple high-current half-H driver. The 293D is designed to provide bidirectional drive current up to 600mA a voltage from 5V to 36V. L293D Adapter Board can be used as dual DC motor driver or bipolar stepper motor driver.
- Dec 21, 2018 L293D Motor Driver IC. The L293D is a dual-channel H-Bridge motor driver capable of driving a pair of DC motors or one stepper motor. That means it can individually drive up to two motors making it ideal for building two-wheel robot platforms. For more details please refer below datasheet.
- The L293D is a popular motor driver IC designed to provide bidirectional drive currents of up to 600-mA at voltages from 4.5 V to 36 V. Compact L293D Motor Driver Board makes it much more convenient to use.
- In this project we are going to control stepper motor using Arduino board and IC L293D (H bridge motor controller), yes this L293D IC and Shield can be used to control stepper motor, have additional DC power source depends on voltage rating of stepper motor you have.
- Manufacturer part number: L293D Documentation Links. Datasheet (pdf download) This is a dual H-Bridge motor driver IC for DC motors or Stepper Motors. It is in a 16-Pin DIP IC Package and is breadboard friendly. This IC allows your Arduino or other microcontroller to easily control 2 DC motors, 1 Stepper motor, or 4 Solenoids or Valves.
L293D IC is a typical Motor Driver IC which allows the DC motor to drive on any direction. This IC consists of 16-pins which are used to control a set of two DC motors instantaneously in any direction.
Hardware (L293D)
Run four solenoids, two DC motors or one bi-polar or uni-polar stepper with up to 600mA per channel using the L293D. These are perhaps better known as 'the drivers in Adafruit Motorshield'. If you accidentally damaged the drivers in a shield, you can use one of these puppies to replace it. Or you can breadboard something on your own! Each chip contains two full H-bridges (four half H-bridges). That means you can drive four solenoids, two DC motors bi-directionally, or one stepper motor. There's a PWM input per driver so you can control motor speed. Runs at 5V logic. Good for motor voltages from 4.5V up to 36V! This wont work well for 3V motors. The motor voltage is separate from the logic voltage.
The stepper motor has five leads, and we will be using both halves of the L293D this time. This means that there are a lot of connections to make on the breadboard. The motor has a 5-way socket on the end. Push jumper wires into the sockets to allow the motor to be connected to the breadboard.
Note that the red lead of the Stepper motor is not connected to anything.
Use the colors of the leads to identify them, not the position from which they emerge from the motor.
Bipolar Stepper Motor
Driving a bipolar stepper motor with the L293D is very similar to driving a unipolar stepper motor. The pulse sequence is the same. The only difference between driving a unipolar stepper motor and driving a bipolar stepper motor is that there is an extra wire in a unipolar stepper motor you have to hook up.
The project designed around L293D IC. The L293D device is quadruple high-current half-H driver. The 293D is designed to provide bidirectional drive current up to 600mA a voltage from 5V to 36V. L293D Adapter Board can be used as dual DC motor driver or bipolar stepper motor driver. Useful in robotics application, bidirectional DC motor controller and stepper motor driver. Separate logic supply to reduce dissipation. L293D includes the output clamping diodes for protections.
