In the last couple of months, many Arduino boards have been added to our product range. But what is the difference between every board? And what can they be used for? Look no further and follow this ultimate Arduino guide!
For those of you who are just getting started with programming and Arduino, we will start off by sharing some great links that will explain Arduino.
If you are already familiar with Arduino, you can scroll down to our extensive overview of all available Arduino boards. And when we say extensive, we mean extensive!
Lastly, we will help you decide on which board to choose for your project and inspire you with some cool Arduino accessories. Sit back, relax and enjoy!
Arduino explained
Who better to explain Arduino, than the people from Arduino themselves?!
On the introduction page of the Arduino website, you can find a thorough explanation of what an Arduino is exactly. If I were to describe it, I’d say that it is a credit-card-sized computer or microcontroller that can receive inputs and turn them into outputs. An input can be the light that shines on a sensor, a sound captured by a microphone or even a text message. Whereas an output can be lighting up an LED, activating a buzzer, rotating a motor and so on.
On that same page, you can also find out why you should choose to use Arduino for your next project! In short, it’s inexpensive and simple to use because of its clear programming environment.
You can tell the Arduino what it needs to do by writing a set of instructions in the Arduino programming language by using the Arduino development environment. Sound difficult? No way! Just go to the getting started page on the Arduino website where you can find all instructions and loads of tutorials to help you on your way!
Overview of the available boards
In the previous chapter, we talked about the different Arduino hardware boards. At Velleman, we have 3 different types of boards:
- Original Arduino boards designed & produced by Arduino, traded by Velleman
- Velleman alteration boards designed by Velleman for Makers, produced & sold by Velleman
- Velleman cloned boards reviewed by Velleman for Makers, produced & sold by Velleman
Each type of board that is sold by Velleman is presented in the following chapters.
Velleman makes a selection of certain boards, based on their own experience and market research. More boards exist on the market.

Boards decision guide
The amount of Arduino boards might seem overwhelming, but there are certain differentiators to look for when choosing a board. To help (new) users, we have created a board decision guide.
Arduino accessories
Arduino projects have a board as the central brain, but you need additional accessories to complete a project. Velleman has a wide selection of shields, interfaces and sensors to assist makers with this.
Our engineering team is constantly inventing, adopting, altering and cloning products on the market. We focus on quality products that enable users to easily adapt technology into their projects. Therefore, we provide a basic Arduino example code with our products and always sell them with original chips.
A perfect example of combining Arduino boards with accessories is the VM211 Earth Listener, an Arduino based sensor device that reads multiple environmental values to indicate the air quality.
The Earth Listener has a pre-programmed VMA101 ATmega2560 MEGA development board as the central brain, combined with the VMA412 2.8 Inch Touch Screen shield, the VMA212 Sensor shield for Arduino Mega, the VMA342 Air quality sensor combo board and the VMA343 Lightning sensor. Together, they make one functional product.
For the full selection of our Arduino compatible shields, interfaces and sensor, have a look at our online Development boards and accessories catalogue.
Some of the most popular accessories are listed below. If you need help finding the right product for your project, be sure to have a look!
Getting started with Arduino
The fastest way to get started with Arduino is by getting your hands on the Arduino starter kit. The Starter Kit includes the components you need to make 15 fun projects following the step-by-step tutorials on the Project Book. The starter kit is available in English and French.
Your first Arduino project: Blink
The Blink program is the easiest and most famous Arduino program. It’s the “Hello world” of Arduino programming!
Even advanced users will try this program first since it tests the basic functionality of an Arduino board & the Arduino software. It is also the program that is pre-programmed into most Arduino boards.
This program shows the simplest thing you can do with an Arduino to see physical output: it blinks the on-board LED. The only thing you need for this workshop is an Arduino UNO board, a USB cable, and a computer.
Follow these steps to create your first project:
- Download the Arduino Software @ http://arduino.cc/en/Main/Software
- Connect the Arduino UNO to your computer (via USB cable)
- Start the Arduino IDE
- Select Board (Arduino UNO)
- Select port
- Start coding
// the setup function runs once when you press reset or power the board
void setup()
{
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}
// the loop function runs over and over again forever
void loop()
{
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
