Introduction One advancing technology that has been impossible to ignore lately has been the work with self driving vehicles. These vehicles have gone from scientific curiosity to mainstream within a few short years and soon we’ll be seeing them as
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 (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!
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
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.
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!
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 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.
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!
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.
