- 3. What is an Arduino?
- 4. The Arduino is an…. • An open-source hardware and software platform project and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building device • Arduino boards are available commercially in preassembled form or as Do-it- yourself (DIY) kits.
- 5. • Arduino board designs use a variety of microprocessors and controllers, intended to make the application of interactive objects or environments more accessible. • Design to make the process of using electronics multidisciplinary projects more accessible • The boards are equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (‘shields) or breadboards (For prototyping) and other circuits. • The microcontrollers can be programmed using C and C++ programming languages.
- 6. Arduino can … • Sense the environment by receiving input from variety of sensors. • Affects its surroundings by controlling lights, motors, and other actuators.
- 7. Programming Environment • The Arduino Uno can be programmed with the Arduino software IDE (Integrated development environment). • The Atmega328 on the Arduino Uno comes preburned with a Bootloader that allows you to upload new code to it without the user of an external hardware programmer. • You can also bypass the Bootloader and program the microcontroller through the ICSP (In-Circuit Serial Programming) header. • Arduino IDE works on windows, linux as well as Mac lion X platforms.

- 9. Advantages of Arduino • Open source • Simplified and user-friendly programming language • No additional programmer/burner hardware required for programming board • Portable • Low power consumption
- 10. The Basic Arduino board
- 13. Features of Arduino UNO • Microcontroller ATmega328 • OperatingVoltage 5V and 3.3V • InputVoltage (recommended 7-12V) • InputVoltage (limit 6-20V) • Digital I/O Pins 14(of which 6 provide PWM output) • Analog Input Pin 6 • DC Current per I/O Pin 40mA DC Current for 3.3V Pin 50mA • Flash Memory 32KB (ATmega328) of which 0.5KB used by Bootloader • SRAM 2KB (ATmega328) • EEPROM 1KB (ATmega328) • Clock Speed 16MHz

- 16. Shields • Arduino and Arduino-compatible boards use printed circuit expansion boards called shields, which plug into the normally supplied Arduino pin headers. • Shields can provide motor controls for 3D printing and other applications, GNSS (satellite navigation), Ethernet, liquid crystal display (LCD), or breadboarding (prototyping). • Several shields can also be made do it yourself (DIY).
- 17. • Some shields offer stacking headers which allows multiple shields to be stacked on top of an Arduino board. • Here a prototyping shield is stacked on two Adafruit motor shieldV2s.
- 18. • Dragino Lora Shield allows the user to send data and reach extremely long ranges at low data rates.
- 19. • Screw-terminal breakout shield in a wing-type format, allowing bare-end wires to be connected to the board without requiring any specialized pins.
- 20. • Adafruit motor shieldV2, this is an upgraded version of the Adafruit’s motor shield which now works over i2C and hence saves a lot of digital I/O pins
- 21. • A USB host shield which allows an Arduino board to communicate with a USB device such as a keyboard or a mouse.
- 22. • Adafruit Motor Shield with screw terminals for connection to motors. Officially discontinued, this shield is still manufactured in China
- 23. • Adafruit Datalogging Shield with a Secure Digital (SD) card slot and real-time clock (RTC) chip along with some space for adding components and modules for customization.
- 24. Applications of Arduino • Home • Automations • Sensor • Prototyping • Robotics • ISP programming • EasyWifi, GSM, Ethernet, Bluetooth, zigbee Connectivity
- 25. Other Prototyping platforms • Raspberry pi • Beagle board • Panda board • Cotton candy • CubieBoard • APC Rock • Hackberry • Gooseberry
- 26. Arduino vs other environment • Support for analog input • Limited Computing power • Comparatively cheap • No GPU unit • Limited memory • PWM output available • Open source
- 27. • Arduino is cheap and versatile open source prototyping environment • It is basically designed for novice, non technical people • Programming language is simple • Arduino has terrific community support and documentation • Technical people can use Arduino for testing sensors or other prototyping work
