- 1. Arduino Part 1 Topics: Microcontrollers ProgrammingBasics: structure and variables Digital Output Analog to Digital Conversion
- 2. What is aMicrocontroller • A small computer on a single chip • containing a processor, memory, and input/output • Typically "embedded" inside some device that they control • A microcontroller is often small and low cost • Examples www.mikroe.com/chapters/view/1
- 3. What is aDevelopment Board • A printed circuit board designed to facilitate work with a particular microcontroller. • Typical components include: • power circuit • programming interface • basic input; usually buttons and LEDs • I/O pins

- 7. Getting Started • Checkout: http://arduino.cc/en/Guide/HomePage 1. Download & install the Arduino environment (IDE) 2. Connect the board to your computer via the UBS cable 3. If needed, install the drivers (not needed in lab) 4. Launch the Arduino IDE 5. Select your board 6. Select your serial port 7. Open the blink example 8. Upload the program

- 13. Add an ExternalLED to pin 13 • File > Examples > Digital > Blink • LED’s have polarity – Negative indicated by flat side of the housing and a short leg www.instructables.com
- 14. A Little BitAbout Programming • Code is case sensitive • Statements are commands and must end with a semi-colon • Comments follow a // or begin with /* and end with */ • loop and setup

- 17. Digital I/0 pinMode(pin, mode) Setspin to either INPUT or OUTPUT digitalRead(pin) Reads HIGH or LOW from a pin digitalWrite(pin, value) Writes HIGH or LOW to a pin Electronic stuff Output pins can provide 40 mA of current Writing HIGH to an input pin installs a 20KΩ pullup www.mikroe.com/chapters/view/1
- 18. Arduino Timing • delay(ms) –Pauses for a few milliseconds • delayMicroseconds(us) – Pauses for a few microseconds • More commands: arduino.cc/en/Reference/HomePage
- 19. Digital? Analog? • Digitalhas two values: on and off • Analog has many (infinite) values • Computers don’t really do analog, they quantize • Remember the 6 analog input pins---here’s how they work todbot.com/blog/bionicarduino
