INTRODUCTION TO THE ARDUINO MICROCONTROLLER

 What is Arduino 

Arduino Uno

 Arduino is an open-source hardware and software, projects, and user community that designs & manufactures single-board microcontrollers. 

Computer on a single integrated chip
– Processor (CPU)
– Memory (RAM / ROM / Flash)
– I/O ports (USB, I2C, SPI, ADC)
• Common microcontroller families:
– Intel: 4004, 8008, etc.
– Atmel: AT and AVR
– Microchip: PIC
– ARM: (multiple manufacturers)
• Used in:
– Cellphones,
– Toys
– Household appliances
– Cars
– Cameras

TheATmega328PMicrocontroller

• AVR 8-bit RISC architecture
• Available in DIP package
• Up to 20 MHz clock
• 32kB flash memory
• 1 kB SRAM
• 23 programmable I/O
channels
• Six 10-bit ADC inputs
• Three timers/counters
• Six PWM outputs

It’s a movement, not a microcontroller:

Arduino

Download Arduino compiler and development environment from:

http://arduino.cc/en/Main/Software
• Current version: 1.0.1
• Available for:
– Windows
– Mac OX
– Linux
• No installer needed... just unzip to a convenient location
• Before running Arduino, plug in your board using a USB cable
(external power is not necessary)
• When a USB device is not recognized, navigate to and select the
appropriate driver from the installation directory
• Run Arduino
