Is L293D an H-Bridge?

An H-Bridge is nothing but an electronic circuit. Using such a circuit, you can supply current in two directions. The L293D is an H-Bridge with two possible outputs. Meaning, you can connect two things to it… and you can control the direction of current flow in both.

What is the L293D H-Bridge and what does it do?

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.

What is the function of motor driver shield?

The Arduino Motor Shield allows you to easily control motor direction and speed using an Arduino. By allowing you to simply address Arduino pins, it makes it very simple to incorporate a motor into your project. It also allows you to be able to power a motor with a separate power supply of up to 12v.

How do you use the L293D motor driver shield?

Start by plugging the shield on the top of the Arduino. Next, connect power supply to the motors. Although you can connect DC motors having voltages between 4.5 to 25V to the shield, in our experiment we are using DC Motors that are rated for 9V. So, we will connect external 9V power supply to the EXT_PWR terminal.

What is motor driver L293D?

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.

What is a dual H-bridge?

An H-bridge is an electronic circuit that switches the polarity of a voltage applied to a load. These circuits are often used in robotics and other applications to allow DC motors to run forwards or backwards. In particular, a bipolar stepper motor is almost always driven by a motor controller containing two H bridges.

What is H bridge motor driver?

What is a L293D motor driver?

The L293D is a 16 pin IC, with eight pins, on each side, dedicated to the controlling of a motor. There are 2 INPUT pins, 2 OUTPUT pins and 1 ENABLE pin for each motor. L293D consist of two H-bridge. H-bridge is the simplest circuit for controlling a low current rated motor.

What is H-bridge IC?

An H-bridge is an electronic circuit that switches the polarity of a voltage applied to a load. These circuits are often used in robotics and other applications to allow DC motors to run forwards or backwards.

What is the l293d motor driver shield?

The L293D motor driver shield includes two L293 motor driver ICs and a 74HC595 shift register IC. The shield has several important components. The motor driver: The L293D is a dual-channel H-bridge motor driver that can control two DC motors or a stepper motor at one time.

How many motors can the l293d handle?

The motor driver: The L293D is a dual-channel H-bridge motor driver that can control two DC motors or a stepper motor at one time. As there are two L293D ICs on the shield, it’s technically capable of controlling a total of four DC motors. This is ideal for two and four-wheel robot platforms.

How many motors can the motor driver Shield Drive?

Perfect for most mechatronics projects! The motor driver shield comes with two L293D dual-channel H-Bridge motor ICs, so it can individually drive up to four dc motors. The shield offers a total of four H-Bridges and each H-bridge can deliver up to 600mA drive current to the dc motor.

How many H-Bridges does an Arduino motor Shield have?

The shield offers a total of four H-Bridges and each H-bridge can deliver up to 600mA drive current to the dc motor. The next key component of the motor shield is the 74HC595 shift register IC that extends 4 digital pins of the Arduino to the 8 direction control pins of the L293D ICs.
