This ppt is a submission of OER by preeti, anurag and rajesh

1. Intro to the Arduino
Topics:
The Arduino
Digital IO
Analog IO
Serial Communication

2. Topic 1: Meet Arduino Uno

3. Getting Started
• Check out: http://arduino.cc/en/Guide/HomePage
1. Download & install the Arduino environment (IDE)
(not needed in lab)
2. Connect the board to your computer via the USB
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

4. Arduino IDE

8. Topic 2: Digital Input/Output
• Digital IO is binary
valued—it’s either on
or off, 1 or 0
• Internally, all
microprocessors are
digital, why?
1
0

9. Arduino Digital I/0
pinMode(pin, mode)
Sets pin 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

10. Our First Program

11. Assignment 1: Digital IO
• Use a push-button to turn ON/Off LED

12. Note
• Assignments and quiz are to be submitted
by 5th August 2016 on line

13. Some Commands
• Serial.begin()
- e.g., Serial.begin(9600)
• Serial.print() or Serial.println()
- e.g., Serial.print(value)
• Serial.read()
• Serial.available()
• Serial.write()
• Serial.parseInt()
• Example Program

14. Serial-to-USB chip---what does it do?
Image from Theory and Practice of Tangible User Interfaces at UC Berkley
The LilyPad and Fio Arduino require an external USB to
TTY connector, such as an FTDI “cable”.
In the Arduino Leonardo a single microcontroller runs the
Arduino programs and handles the USB connection.

15. Assignment 2: Serial
Communication
Modify your program from in-class
exercise 2-part 2 to control the
intensity of the LED attached to pin 9
based on keyboard input.
Use the Serial.parseInt() method to
read numeric keyboard input as an
integer.
An input of 9 should produce full
intensity and an input of 0 should turn
the LED off.
