L293D Motor Drive Shield Expansion Board Mega2560 UNO R3

Features

L293D Motor Drive Shield Expansion Board Mega2560 UNO R3

• Can drive 4 DC motors or 2 stepper motors or 2 Servo
• Up to 4 bi-directional DC motors with individual 8-bit speed selection
• Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil or interleaved stepping.
• 4 H-Bridges: per bridge provides 0.6A (1.2A peak current) with thermal protection, can run motors on 4.5V to 36V DC
• Pull-down resistors keep motors disabled during power-up
• reset button
• 2 external terminal power interface, for separate logic/motor power supplies

L293D Motor Drive Shield Expansion Board Mega2560 UNO R3 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’s 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. motor.

What is Arduino Shield?

Arduino shields are the boards, which are plugged over the Arduino board to expand its functionalities.

For example, Ethernet shields are used to connect the Arduino board to the Internet. The pin position of the shields is similar to the Arduino boards.

Arduino is an open-source hardware and software company, project and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices. Its hardware products are licensed under a CC-BY-SA license, while the software is licensed under the GNU Lesser General Public License (LGPL) or the GNU General Public License (GPL), permitting the manufacture of Arduino boards and software distribution by anyone. Arduino boards are available commercially from the official website or through authorized distributors.

Arduino board designs

Use a variety of microprocessors and controllers. The boards are equipped with sets of digital and analogue input/output (I/O) pins that may be interfaced to various expansion boards (‘shields’) or breadboards (for prototyping) and other circuits. The boards feature serial communications interfaces, including Universal Serial Bus (USB) on some models, which are also used for loading programs. The microcontrollers can be programmed using the C and C++ programming languages, using a standard API which is also known as the “Arduino language”. In addition to using traditional compiler toolchains, the Arduino project provides an integrated development environment (IDE) and a command-line tool (Arduino-CLI) developed in Go.

What year did Arduino begin?

The Arduino project began in 2005 as a tool for students at the Interaction Design Institute Ivrea in Ivrea, Italy, aiming to provide a low-cost and easy way for novices and professionals to create devices that interact with their environment using sensors and actuators. Common examples of such devices intended for beginner hobbyists include simple robots, thermostats and motion detectors.

Where did the name come from?

The name Arduino comes from a bar in Ivrea, Italy, where some of the founders of the project used to meet. The bar was named after Arduin of Ivrea, who was the margrave of the March of Ivrea and King of Italy from 1002 to 1014.
