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.

There are some choices to be made when installing Arduino software and drivers in Windows 10. Arduino offer two ways of installing the Arduino IDE on a Windows PC — Windows installer file and a Windows zip file. Windows 10 will also install a default driver when an Arduino is plugged into the USB port of a PC. This driver can be replaced by the Arduino driver that comes with the Arduino software.
Arduino Software and Drivers
Installing Arduino software using the Windows zip file is the simplest method of installing the software. It is just a matter of copying the folder out of the downloaded zip file into the desired location on the PC. This allows the software to easily be removed by deleting the folder.
When Windows 10 installs a driver automatically, the Arduino just looks like a COM port in Windows Device Manager. It is not recognized as an Arduino, although it will work properly and code from the Arduino IDE can be loaded to it. After installing the Arduino driver that comes with the Arduino software, the Arduino will be shown as an Arduino on a COM port in Device Manager. The difference is shown in the image below.
Windows Default COM Driver and Arduino Driver
As can be seen in the image, with the default Windows 10 driver installed, the Arduino appears as USB Serial Device (COM4) (left), but after the Arduino driver is installed the same Arduino appears as Arduino Uno (COM4) (right).
Full instructions on installing the Arduino IDE software and updating the Arduino driver can be found in the article on how to install Arduino software and drivers on Windows 10.
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.

Arduino Ethernet shield tutorial explains how to set up an Arduino and Ethernet shield as a web server.
Getting sensor data from an Arduino and sending it over the Internet to display the data in a graph can be a rather challenging task. This task is made extremely easy when using a IoT (Internet of Things) web service instead of setting up the Arduino to host a web page that contains the sensor data graph. Any Arduino board that has Ethernet on it or any Arduino board with an Ethernet shield can be used to make an Arduino Internet graph.
Arduino Internet Graph
An Arduino Internet graph can easily be made by using the ThingSpeak platform to do all the hard work like capturing the sensor data and plotting it to a graph. The image below shows Arduino analog pin A0 voltage plotted on a graph that is displayed in an account on the ThingSpeak website.
Arduino Internet Graph
How it Works
A ThingSpeak library is installed in the Arduino IDE using the Arduino library manager. The library provides functions that can be used to communicate with the ThingSpeak web server.
A free account can be opened on the ThingSpeak website which allows channels to be created. Data from the Arduino, which can be sensor data, voltage, or any other data, can then be sent to the channel and plotted on a graph at the website. Each channel can have up to eight fields, enabling data from up to eight sensors to be sent over one channel.
When using ThingSpeak, no SD card is needed and the Arduino and Ethernet shield or other Arduino board that has Internet capabilities is set up as a client rather than a server. No special Internet router settings need to be made when the Arduino is used as an Internet client, making setup and use very easy.
