Learning about shields and modules for Arduino

Página 12

Shields and modules for Arduino are essential components for learning and practicing robotics and automation. They allow you to expand your Arduino's capabilities, allowing it to interact with the physical world in new and exciting ways.

What are Shields and Modules for Arduino?

Arduino Shields are boards that can be attached to the main Arduino board to extend its capabilities. They contain components and circuits that allow the Arduino to do things it couldn't do on its own. For example, an Ethernet Shield allows Arduino to connect to the internet, while a Motor Shield allows Arduino to control DC and stepper motors.

Arduino modules, on the other hand, are small circuits that can be connected to the Arduino to add specific functionality. They are generally simpler than Shields and are used for specific functions such as detecting light, measuring temperature, sending infrared signals, etc.

Learning about Shields for Arduino

There are many different Shields available for the Arduino, each with its own functions and characteristics. Here are some of the most common and useful ones:

1. Ethernet Shield: This Shield allows the Arduino to connect to the internet. It contains a W5100 Ethernet chip that allows the Arduino to communicate using the TCP/IP protocol. With this Shield, you can do things like send and receive data over the internet, create a web server on your Arduino, and much more.

2. Motor Shield: This Shield allows the Arduino to control DC and stepper motors. It contains an L298N motor controller that can control up to four DC motors or two stepper motors. With this Shield, you can do things like build a robot that moves, control the movement of a CNC machine, etc.

3. LCD Shield: This Shield allows Arduino to control LCD displays. It contains an LCD controller that can control 16x2 character LCD displays. With this Shield, you can do things like display texts and graphics on your Arduino, create a user interface for your project, etc.

Learning about Modules for Arduino

As with Shields, there are many different modules available for the Arduino. Here are some of the most common and useful ones:

1. Temperature Sensor Module: This module allows the Arduino to measure temperature. It contains a DS18B20 temperature sensor that can measure temperatures from -55°C to +125°C with an accuracy of ±0.5°C. With this module, you can do things like monitor the temperature of a room, create a digital thermostat, etc.

2. Light Sensor Module: This module allows the Arduino to detect light. It contains an LDR (Light Dependent Resistor) light sensor that changes its resistance according to the amount of light it receives. With this module, you can do things like turn on a light automatically when it gets dark, create a light meter, etc.

3. Infrared Transmitter Module: This module allows the Arduino to send infrared signals. It contains an infrared LED that can emit infrared signals that can be detected by an infrared receiver. With this module, you can do things like control infrared devices like TVs and air conditioners with your Arduino.

In summary, Arduino Shields and Modules are essential components that allow the Arduino to interact with the physical world in new and exciting ways. By learning about them, you can expand your robotics and automation skills and create more complex and interesting Arduino projects.
