What is Arduino?
A microcontroller board, contains on-board power supply, USB port to communicate with PC, and an Atmel microcontroller chip.
It simplify the process of creating any control system by providing the standard board that can be programmed and connected to the system without the need to any sophisticated PCB design and implementation.
- It is an open source hardware, any one can get the details of its design and modify it or make his own one himself.
- It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.
- It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.
- Arduino UNO differs from all preceding boards because it does not use the FTDI USB-to-serial driver chip.
