Using Servo Motors with the Arduino

Servo Motors are a staple for hobbyists in a variety of fields. Whether you’re building model planes and boats or working with robotics you are sure to come up with dozens of applications just perfect for a servo motor.

Come and explore the use of inexpensive analog servo motors. They are inexpensive and easy to use. When coupled with an Arduino you can build all sorts of projects that move.

And if you need LOTS of servo motors we have just the thing for you – the PCA9685 16 Channel PWM controller. Using this board you can control 16 servos with just two connections to your Arduino. And you can expand that to 992 servos if you really need a lot of motors!

RGB LEDS – Colorful Arduino Experiments

RGB (Red-Green-Blue) LEDs are versatile devices that can add color and functionality to your Arduino projects.

In this article we’ll examine the different types or RGB LEDs available to experimenters and see how to best use them with an Arduino. It promises to be a very colorful read!

Arduino Visual Programming – Getting Started with XOD

XOD is a free visual programming language that makes Arduino programming simple for anyone, without writing a single line of code!

This is the first article in a series about using XOD with the Arduino. In this article you’ll learn what XOD is, how to install it and how to create your first XOD programs

Using LCD Displays with Arduino

Liquid Crystal Displays or LCDs are an excellent way to display characters and data in your Arduino projects. They are inexpensive and very easy to use.

In this article you’ll learn how to add LCD displays to your Arduino project, both hardwired and using the I2C bus connection. You will also learn to use a popular LCD Keypad Shield which as a 2-line LCD along with 6 push buttons.

Wireless Joystick for Arduino Robot Car with nRF24L01+

Learn to use the popular nRF24L01 radio modules with an Arduino, using the RadioHead library.

In this article we will conduct several experiments sending data between two Arduinos with the nRF24L01. We will then take what we have learned and build a wireless joystick controller for our robot car!

Using Inexpensive 433MHz Transmit and Receive Modules with Arduino

Those inexpensive RF transmitter and receiver modules that you can get on eBay and Amazon are perfect when you need a low-cost method of sending one-way data between two Arduinos.

In this article you’ll learn how these modules work and how to use them in your next Arduino project.

Stepper Motors with Arduino – Getting Started with Stepper Motors

Stepper motors are used in a variety of devices ranging from 3D printers and CNC machines to Blu Ray drives, cameras and even analog clocks.

In this article you’ll learn how steppers work, the difference between bipolar and unipolar stepper motors and how to control both of them with an Arduino.

Using IR Remote Controls with Arduino

IR Remote controls are all around us in every room of our homes. Using an Arduino we can decode and repurpose our existing IR Remotes and build our own custom remote controls

In this article you’ll learn how IR Remote Controls work and how to use inexpensive IR sensors and LEDs to do magic things with infrared light!

Build a Robot Car with Speed Sensors

I’m sure you have seen those inexpensive robot car chassis kits, the ones that come with two 6-volt motors. They are great fun and very useful and they even come with a couple of speed encoder disks (those little black circles full of holes). Problem is, no one tells you how to use them!

Let’s resolve that and build a robot car with speed sensors. Along the way we’ll learn how to use Interrupts, a valuable programming technique.

Using the HC-SR04 Ultrasonic Distance Sensor with Arduino

The HC-SR04 Ultrasonic Distance Sensor is a staple in robotics projects. This inexpensive device is capable of measuring the distance between itself and the nearest solid object from 2 to 400 centimeters. Exactly what you need to keep your bots from driving into walls!

In this article we’ll look at this sensor in depth, including ways to make it even more accurate by compensating for temperature and humidity. There’s lots of Arduino code to be has as well, so dig in!
