This is a good example of how you can expand your arduino as you progress with your skills.

It keeps going up and up... lol... so many possibilities.

It can even be a robot??? lol

Close up with an Arduino Board...

Please look very carefully on this picture... Very important to know is where are the DIGITAL pins and where are the ANALOG pins.

DIGITAL pins - are the output. this is where the signal will be coming from for our devices.

ANALOG pins - are the input. This is where arduino sense its environment... maybe a "temp sensor" ? or maybe a "PH" meter? etc.

Also pay special attention to where all the PWM pins are... Very handy if you know this now before you continue... Do you see it? Look at the digital pins (upper right)... you will see PWM written on the board.... and these repeats on PINS 3, 5, 6, 9, 10, and 11. Only 6 PWM pins for those boards that uses atmega168. I believe this is more than enough for our LED DIMMING CONTROLLER project.
