A Raspberry Pi (sometimes just called a Pi for short) is a very small computer. Raspberry Pi is a popular alternative to Arduino, BASIC Stamp, and other types of microcontrollers and is the ideal computer for people who love to make their own gadgets.Physically, a Raspberry Pi resembles an Arduino or a BASIC Stamp.

Before you can fire up your Raspberry Pi and start building your own electronics projects, you need to do some basic setup work. Start by setting up the hardware. You'll need the following to set up your Pi so that you can program it for your projects: A Raspberry Pi 2 or 3. A suitable power supply: The Raspberry Pi requires a 5 V power supply connected via a micro-USB connection on the card.

General-purpose input/output (GPIO) ports make Raspberry Pi much more than just a very small computer. GPIO ports allow you to control your own electronic circuits directly from the Pi. The 40-pin GPIO header on the Raspberry Pi 2 and 3 provides access to a total of 17 GPIO ports that can be controlled from programs you write in Python or other languages.

There are several different ways to design a color organ circuit. Most of them rely on a special type of electronic component called a triac, which is essentially a transistor that's designed to work with alternating current.It has three terminals. Two are anodes, called A1 and A2, and the third is a gate. A voltage at the gate — either positive or negative — allows the anodes to conduct.

Simply put, a color organ converts the volume of an audio input into an output voltage that gets higher as the sound source gets louder. If you connect a light to the output, the light will glow brighter when the audio input is louder and dimmer when the input is quieter.One of the great things about Disneyland is that sometimes the long line you have to wait in to go on a particular ride is almost as good as the ride itself.
