Most of the initial work with color involved sensory experiences rather than actual attributes of the physical world. It was Newton who came up with the concept of the “color wheel”, a chart that describes the usage of “complementary colors” that is still in use today. Initial work on color theory was performed as early as the mid 1400’s and early work with the science of color was undertaken by such luminaries as Leonardo da Vinci and Isaac Newton. Color TheoryĬolor theory is the study of the mixing of colors to produce a specific visual effect. An Arduino can be used with either type or LED.īefore we get started on lighting up our projects with RGB LEDs let’s take a quick look at some color theory, this will help you understand how we can create a multitude of colors with just three primary ones. Standard RGB LEDs can be used as stand-alone devices while Intelligent RGB LEDs require a controller or microcontroller. There are many different varieties of RGB LEDs, today we will look at two different types: In addition to being able to emit their three primary colors RGB LEDs can be used to display virtually any color of the rainbow by fusing together combinations of their three colors. Look Arduino Built-In Examples: įor example: if the sensor value is bigger then a certain value, the motor will start to vibrate.ģ.use a stretch sensor to generate tones and pitch.Īnd wire the sensor and motor according to the diagram below.RGB or Red-Green-Blue LEDs are a fusion of three LEDs in a single package. use the stretch sensor value to turn on the vibration motor. Note: don't forget to change the input pin number.Ģ. You can reference on Arduino Built-In Examples: Read the analog value of the Photoresistor: modified by Scott Fitzgerald */ // the setup function runs once when you press reset or power the board void setup () ġ.

If you're unsure what pin the on-board LED is connected to on your Arduino model, check the documentation at This example code is in the public domain. On the Uno and Leonardo, it is attached to digital pin 13. Most Arduinos have an on-board LED you can control. * Blink Turns on an LED on for one second, then off for one second, repeatedly. it is a basic test to check and run a simple script at the same time. We start by figuring put if our Arduino is all good or it is somehow damaged. The Arduino has several different kinds of pins, each of which is labeled on the board and used for different functions. They usually have black plastic ‘headers’ that allow you to just plug a wire right into the board. The pins on your Arduino are the places where you connect wires to construct a circuit (probably in conjunction with a breadboard and some wire.

In the meantime, HERE you can find ANYTHING about Arduino, including download the software You use the IDE to createa sketch (a little computer program) Or can be connected to software on your computer.Īrduino is composed of two major parts: the Arduino board, which is the piece of hardware you work on when you build your objects Īnd the Arduino IDE, the piece of software you run on your computer. Arduino can be used to develop standalone interactive objects In explaining microcontrollers, we’ll distinguish them from computers, which contain more powerful processors that can run an operating system.Īrduino is an open source physical computing platform based on a simple input/output (I/O) board and a development environment that implements the Processing language. 1.1.1.1 Go to File -> Examples -> Basics ->BlinkĬomputer and processor are generic terms for anything that can run a program, basically.Ī controller or microcontroller usually refers to a simple processor that does only one task, like listening to sensors.
