arduino for beginners – Setting Up – Part 2

This tutorial is about arduino and we going to learn some basics things together. In this Part we going setting up arduino.

Buying an arduino:
Getting an arduino board, we going use Arduino uno.

Other Components we need:

-USB Cable.
-Breadboard.
-Flexible Wires.
-Push Button.
-Potentiometers.
-Resistors.
-LEDs.
-RGB LED.

The Arduino Board:

Microcontroller	ATmega328
Operating Voltage	5V
Input Voltage (recommended)	7-12V
Input Voltage (limits)	6-20V
Digital I/O Pins	14 (of which 6 provide PWM output)
Analog Input Pins	6
DC Current per I/O Pin	40 mA
DC Current for 3.3V Pin	50 mA
Flash Memory	32 KB (ATmega328) of which 0.5 KB used by bootloader
SRAM	2 KB (ATmega328)
EEPROM	1 KB (ATmega328)
Clock Speed	16 MHz
Length	68.6 mm
Width	53.4 mm
Weight	25 g

Note : The 6 Digital I/O (Provide PWM output) with the tide ~ symbol next to the number on the board, they allow for Pulse width Modulation (PWM), witch is a technique for controlling power and simulation an analog signal on a digital input pin. One reason to use these pins might be to control brightness LESs.
