Intro to arduino

Arduino is an open-source platform that's all about hands-on learning and creating with technology. It's a powerful tool for building your own electronic devices, gadgets, and robots. At its core, Arduino consists of a small computer, often called a microcontroller, and software called Arduino IDE (Integrated Development Environment).

The microcontroller is like the brain of your project. You can program it to make lights blink, motors turn, and sensors react to their surroundings. It's all about making things happen with code. Arduino IDE is where you write the code, and then you upload it to the microcontroller. This software makes it easier for you to give precise instructions to the microcontroller.

One cool thing about Arduino is that it provides a standard form factor, which means it has a set size and shape. This makes it easy to connect different parts and components to the microcontroller. It's like building with blocks – everything fits together neatly. With Arduino, you can learn the fundamentals of electronics, coding, and engineering, and use your creativity to bring your projects to life.

Board Types

Various kinds of Arduino boards are available depending on different microcontrollers used. However, all Arduino boards have one thing in common: they are programed through the Arduino IDE.

The differences are based on the number of inputs and outputs (the number of sensors, LEDs, and buttons you can use on a single board), speed, operating voltage, form factor etc. Some boards are designed to be embedded and have no programming interface (hardware), which you would need to buy separately. Some can run directly from a 3.7V battery, others need at least 5V.

Arduino Uno
  • Arduino Uno: This is one of the most popular and widely used Arduino boards. It is great for beginners and comes with a variety of input and output pins, making it suitable for a wide range of projects.
  • Arduino Mega: The Arduino Mega offers more digital and analog input/output pins compared to the Uno. This makes it suitable for larger and more complex projects.
  • Arduino Nano: The Nano is a compact version of the Uno, making it suitable for projects with space constraints. It has similar capabilities but in a smaller form factor.
  • Arduino Leonardo: The Leonardo is unique because it has built-in USB capabilities. It can act as a keyboard or mouse, making it suitable for projects that require human interface devices.
  • Arduino Due: The Due is a powerful board with a 32-bit ARM microcontroller. It is ideal for more computationally intensive projects and applications that require high performance.
  • Arduino Pro Mini: Similar to the Nano, the Pro Mini is a compact board designed for embedded applications. It lacks a USB interface, so an external adapter is needed for programming.
  • Arduino Lilypad: The Lilypad is designed for wearable electronics and e-textile projects. It's sewable and can be integrated into clothing and textiles.
  • Arduino Yun: The Yun combines the power of an Arduino with a small Linux-based computer. It's great for IoT (Internet of Things) projects and applications that require web connectivity.

  •  Arduino MKR Series: The MKR series includes various boards designed for IoT applications. These boards are compact and offer connectivity options like Wi-Fi and cellular. 
  • Arduino Pro Micro: The Pro Micro is a small board with a micro USB port. It's often used for small, low-power projects.
  • Arduino Zero: The Zero is based on the Atmel SAMD21 microcontroller and is designed for applications that require more processing power.

we will learn about the different components on the Arduino board. We will study the Arduino UNO board because it is the most popular board in the Arduino board family. In addition, it is the best board to get started with electronics and coding. Some boards look a bit different from the one given below, but most Arduinos have majority of these components in common.
