The document provides an overview of Arduino, including what it is, its history, types of Arduino boards, and the Arduino UNO board. Arduino is an open-source hardware and software company that designs and manufactures microcontroller kits for building digital devices. It was founded in 2005 to provide a low-cost option for students and designers to control interactive objects. Popular Arduino boards include the UNO, MEGA, LilyPad, and Yun. The Arduino UNO has an ATmega328P microcontroller, 14 digital input/output pins, 6 analog pins, a 16MHz clock speed, and runs on a 5V power supply.

- 3. What is Micro-Controller? It is a micro-computer. As any computer it has internal CPU, RAM, IOs interface. It is used for control purposes, and for data analysis.
- 4. What is Arduino? A microcontroller board, contains on- board power supply, USB port to communicate with PC, and an Atmel microcontroller chip.
- 5. Arduino vs other environments • Support for analog input • Limited Computing power • Comparatively cheap • No GPU unit • Limited memory • PWM output available • Open source
- 6. History 1.In 2005, a project was initiated to make a device for controlling student-built interactive design projects that was less expensive than other prototyping systems available at the time. 2.Founders Massimo Banzi and David Cuartielles named the project after Arduin of Ivrea and began producing boards in a small factory located in Ivrea.

- 12. General Pin functions of Arduino UNO • LED: There is a built-in LED driven by digital pin 13 • VIN: The input voltage to the Arduino/Genuino board when it's using an external power source • 5V: This pin outputs a regulated 5V from the regulator on the board. • GND: Ground pins. • IOREF: This pin on the Arduino/Genuino board provides the voltage reference with which the microcontroller operates. • Reset: Typically used to add a reset button to shields which block the one on the board.
- 13. Special Pin Functions of Arduino UNO • Serial • External Interrupts • PWM(Pulse Width Modulation) • SPI(Serial Peripheral Interface) • TWI(Two Wire Interface) • AREF(Analog REFerence)
- 14. Sensors • Digital, Analog sensors. • Light sensors: - Photo-Resistor [photo-cell]. - Photo-Diode. - Photo-Transistor.
