Arduino

Arduino is an open-source physical computing platform designed to make experimenting with electronics more fun and intuitive. Arduino has its own unique, simplified programming language, a vast support network, and thousands of potential uses, making it the perfect platform for both beginner and advanced DIY enthusiasts.

circuit 1

simple circuit with a LED with a 1 second delay (for on and off)

same circuit just with a alot less delay. This makes the blink almost impossible to see.

delay(15); // Wait for 15 milliseconds

digitalWrite(13, LOW); // Turn off the LED

delay(15); // Wait for 15 milliseconds

circuit 2

A potentiometer, or "pot" for short, is a control knob.

It's the same type of control you'd use to change volume,

dim a lamp, etc. A potentiometer changes resistance as it

is turned. By using it as a "voltage divider", the Arduino

can sense the position of the knob, and use that value to

control whatever you wish.

(The blue nob is the potentiometer)

circuit 3

the light slowly changes between red, blue, green, and purple.
