Hardware projects
And something else, which we'll start with before trying to regulate our traffic.
We'll use LEDs (Light Emitting Diode): 1 red, 1 yellow and... ?!?!
yes, 1 green.
In the first part every LED will be gradually turned from off to on and viceversa.
After that, the traffic lights: just one LED on.
We need following stuff:

This is an introduction of the method that we will use and offer in order to construct our self constructed hardware.Hardware projects can have various natures, can be analog or digital.Analogue electronics are the electronic systems that have a continuously variable signal, in contrast to digital electronics where signals (usually) have only two levels.

In this article we will present one possible method to put a bootloader into a virgin Arduino's ATMega 328P.
We'll utilize :

You have an Arduino board and you bought a new ATMega328 microcontroller for new projects; after mounted it onto the board you discovered it doesn't work.
Why this?
In picture beside we can see something interesting: "avrdude" and specially "not in sync"; simply it's impossible to communicate or send datas to ATMega: it's not ready!
"Ready? what does it mean"!?
Think you have a baby: he's not ready to take care of himself, but you are, both for him and for you!
Same with microcontroller: control it by external hardware (adult to baby), or give it (baby) the way to become independent.
We're covering this second aspect, that needs a little piece of code.
Sensoristic applying field is fascinating, and sometimes sounds magic or something common people cannot approach immediately.
Our body is full of sensors (like ears) able to capture vibrations or other stuff: so you natively have parameters which to confront and start with.
