In this blog post we look at how beginners wanting to start with Arduino can choose an Arduino board. Help is provided for beginners choosing an Arduino. The difference between an Arduino and AVR ATmega microcontroller is also covered.
Choosing an Arduino for Beginners
The recommended Arduino for beginners is usually the Arduino Uno. On the Starting Electronics website, the article on choosing an Arduino for beginners provides more information on which Arduino to choose when starting to learn about Arduino and writing sketches.
Difference Between Arduino and AVR
Many Arduino beginners are confused about the difference between Arduino and AVR, or Arduino and ATmega. Difference between Arduino and ATmega328 explains what the ATmega328 microcontroller is and how it relates to the Arduino Uno. The article also explains more about the AVR microcontroller found on most Arduino boards.
A list of easy to build Arduino projects for beginners and kids. These projects use easy to obtain components and can be built on an electronics breadboard. Suitable for use with an Arduino Uno or similar board.
Arduino projects for absolute beginners below list very easy projects for first time Arduino users. The section that follows lists projects for beginners who have learned the basics of how to use an Arduino.
Arduino Projects for Absolute Beginners
The simple projects below are suitable for absolute beginners with Arduino. They are part of a series of tutorials that introduce beginners to basic electronics. For beginners who have not yet used an electronics breadboard, see how to build a simple circuit on breadboard.
Arduino Projects for Beginners

This easy Arduino project for beginners can be built on an electronic breadboard and uses only four LEDs and four series resistors to make a moving light display. The Arduino sketch for the project can be modified to change the rate at which the pattern on the LEDs is updated. The patterns to display on the LEDs can also be changed.
Moving Light Display Arduino Project for Beginners
Details of this Arduino Project for Beginners
A breadboard is used to connect four LEDs with series resistors to an Arduino which can be an Arduino Uno or other Arduino. Four wire links connect the LEDs to four of the Arduino pins which are set as outputs. A common GND wire from the Arduino is connected to the breadboard which connects the other side of each of the series resistors to GND. This completes the circuit and enables the LEDs to be switched on by the sketch running on the Arduino.
Moving LED Arduino Project
The full project includes the circuit diagram, Arduino sketch code and instructions on how to modify the sketch to display different moving light LED patterns on the LEDs.
Other Arduino Beginner Project Resources
Those new to Arduino may be interested in the beginners electronics series of tutorials that includes an introduction to Arduino.
The same tutorial series includes ten Arduino projects for absolute beginners which is a sample of various Arduino built-in examples with instructions on how to build each project.
Arduino Internet voltage monitoring can be achieved in several ways. The Arduino can be set up as a client or a server in order to display measured voltage on a web page. In this article an Arduino is set up as web server that hosts a web page stored on SD card. The web page displays the voltage measured on Arduino analog pin A2 in near real-time. The web server also interacts with ThingSpeak, a Internet of Things (IoT) service which logs voltage over time. Voltage is displayed on the hosted web page on a gauge and in a ThingSpeak generated graph or chart.

ADH Technology, the company that sells the GT-511C3 fingerprint scanner provide SDK software that includes a demo application for running on a PC. The demo software allows the scanner to be used to enrol fingerprints, each with a unique ID and then identify enrolled fingerprints when a finger is placed on the scanner later. The GT-511C3 fingerprint scanner demo software also includes several other functions that allow fingerprints to be deleted, display number of registered fingerprints, etc.
A USB to TTL level device is normally needed to connect the fingerprint scanner to a Windows PC to use the demo application.
Connecting the GT-511C3 Fingerprint Scanner to a PC using an Arduino
The article on interfacing the GT-511C3 to a PC running the demo software provides a quick hack that uses an Arduino Uno as a USB to TTL converter. The Arduino Uno uses a software serial port to connect to the fingerprint scanner because the only hardware serial port on the Uno is connected to the USB chip which is used as the interface to the PC USB port.
Serial data is relayed between the fingerprint scanner and demo software on the PC by a sketch running on the Arduino. The image below shows the demo application and interface to the scanner. Also see the full article that explains the hardware connections and software needed for the project.
