How to Add Keyboard Input to the All-Seeing Eye

You can use keyboard input to set the exact time delay value for your all-seeing eye, which controls how fast you want your eye to move back and forth. You can use the same technique to add numerical keyboard [more…]

LED Cube Pattern Generator

For the LED cube, you have to write the correct code to generate the animation. But writing all of those 1s and 0s can be really tedious. To make things easier, use the LED Cube pattern generator to create [more…]

Ten Links to Online Arduino Learning Resources

If you are interested in learning about Arduino projects, there are loads of things you can discover through some online resources. Check out the following links, which are some favorite online resources [more…]

Add the RFID Reader to Your Keypad Entry System

Both the keypad entry system and the RFID reader are connected to a relay that closes the circuit to whatever is attached. For example, it might be attached to an electronic door strike. But what if you [more…]

Arduino Projects: Resistor Color Codes for Electronics

When building Arduino electronics projects, you often need to consult a schematic or identify a resistor. Use this table to identify a resistor's value, in Ohms, from its color code: [more…]

Arduino Projects Schematic Symbols

When building Arduino projects, you often need to consult a schematic. Have a look at the following table, which shows the common schematic symbols you encounter when building Arduino projects: [more…]

Troubleshooting Your Arduino Electronics Project

If your Arduino electronics project isn't working, you have to check both your hardware and your software. Start with your hardware and then move on to the software. Troubleshoot your electronics project [more…]

Arduino Projects For Dummies Cheat Sheet

Before you begin creating electronics projects with Arduino, get to know the symbols used in schematics; go over a color code chart to help you decipher resistor values; and explore some hardware and software [more…]

11 Great Arduino Resources

If this is your first step into the world of Arduino, you will be relieved to know that you have an abundance of resources available to you on the Internet. You can find new, Arduino-compatible hardware [more…]

10 Places to Find Arduino Parts and Components

You can find many Arduino-related shops in the world, but there are also a number of suppliers that are good to know about when shopping for the right parts and components. [more…]

How to Install Arduino for Windows

These instructions and screenshots describe the installation of the Arduino software and Arduino Uno drivers on Windows 7, but the same instructions work just as well for Windows Vista and Windows XP. [more…]

How to Install Arduino for Mac OS X

These instructions describe an installation of the Arduino Software and drivers for an Arduino Uno on Mac OS X Lion, but will work the same for Leopard, Snow Leopard and Mountain Lion. Previous operating [more…]

How to Complete Your First Arduino Sketch

Once you have the basics, you can now complete your first sketch. In front of you now should be an Arduino Uno R3, a USB cable, and a computer running your choice of operating system [more…]

What You Should Know about the Arduino Environment

Before you start in with sketches, it’s a good idea to know your way around the Arduino environment. Programs written for Arduino are known as sketches [more…]

What You Should Know about Circuit Diagrams for Arduinos

Recreating circuits from photos or illustrations on the Arduino can be difficult, and for that reason, standardized symbols are used to represent the variety of components and connections that you may [more…]

How to Upload a Sketch to an Arduino

The content of circuits and Arduino sketches can vary greatly. Before you get started, there is one simple process for uploading a sketch to an Arduino board that you can refer back to. [more…]

The LED Fade Sketch for the Arduino

In this Arduino sketch, you make an LED fade on and off. You need some extra hardware to make the LED fade on and off. For this project you need: [more…]

The Button Sketch for the Arduino

This is the first and perhaps most basic of inputs that you can and should learn for your Arduino projects: the modest pushbutton. For this Arduino project, you will need: [more…]

The AnalogInput Sketch for the Arduino

The previous sketch showed you how to use a digitalRead to read either on or off, but what if you want to handle an analog value such as a dimmer switch or volume control knob? [more…]

Serial Sketches for the Arduino

These Arduino projects are designed to display the value of inputs using the serial monitor. Serialis a method of communication between a peripheral and a computer. In this case, it is serial communication [more…]

How to Spin a DC Motor with the Arduino

The DC motor in your Arduino kit is the most basic of electric motors and is used in all types of hobby electronics. When current is passed through, it spins continuously in one direction until the current [more…]

How to Change the Speed of a DC Motor with the Arduino

Sometimes you need to have greater control over the speed of your motor, which the Arduino allows you to do with the MotorSpeed sketch. The following shows you how to control the speed of your motor with [more…]

How to Control the Speed of a DC Motor with the Arduino

Need more control of your DC motor? You can use the MotorControl sketch for the Arduino to put some input into a DC motor to give you full control of the motor on the fly. [more…]

How to Create Sweeping Movements with the Arduino

You can create sweeping movements on a servomotor with the Arduino. A servo motor sweeps from 0º to 179º and then back again, in a similar way to the movement of an old rotary clock. [more…]

How to Control Your Servo with the Arduino

By using a potentiometer (or any analog sensor), it’s possible to directly control your servo with the Arduino in the same way that you’d control a mechanical claw at the arcades. [more…]
