The arduino is a miccro-controller. It is a small computer that can control things, like a circuit.
When we use an arduino we usually hook it up to some type of circuit.
In the photo below, the the arduino is hooked up to a simple LED with a resistor.
Once the circuit and arduino are hooked up, we could write a program that causes the LED to blink, then install the program onto th arduino, then run it.
Then we write a program on our computer, upload the program to the arduino, then the arduino executes the program by making lights flash or doing other cool stuff.
The following video provides an introduction to the Arduino and a few simple projects.
It's also important that you read the information on the following link, it will give you an idea of what an arduino is and how to use it.
