The document provides an overview of getting started with Arduino, including types of Arduino boards, breadboard basics, and methods for powering Arduino. It includes step-by-step instructions for programming an LED to blink, as well as explanations of digital and analog input/output, and examples of projects that can be built. The document also contains links to additional resources for further learning and project ideas.
Getting started with arduino workshop
- 1. Getting started with Arduino Hands-on Workshop Sudar Muthu http://hardwarefun.com @hardwarefun
- 2. What is an Arduino? Photo credit: Arduino team
- 3. Types of Arduino • Leonardo, Uno (and older ones) • Yun (Includes a Linux Kernel) • Due (32-bit) • Mega (more input pins) • Arduino BT (includes Bluetooth) • LilyPad (wearable) • Arduino Pro • ADK (supports Android ADK) • Clones (around 300+)
- 6. • The first two and the last two rows are connected • In all the other rows, columns are connected • Connect the first and last row to power • Connect the second and second last row to ground http://hardwarefun.com 6 How to use a breadboard
- 8. • Using USB cable • Using DC power jacket • Giving voltage directly into Vin pin • Giving regulated voltage directly into 5V pin http://hardwarefun.com 8 Different ways to power up Arduino
- 10. Testing The Setup With A “Hello World” Program http://hardwarefun.com 10
- 12. • Insert a LED in pin 13 • Open File->Examples->Basics->Blink • Select Tools->Boards->Arduino Uno • Select File->Upload (or press ctrl+u) • You should get the message “Done upload” • Your Led should blink • Congrats you can program Arduino now http://hardwarefun.com 12 Making a LED blink
- 13. Anatomy Of An Arduino Sketch http://hardwarefun.com 13
- 14. Things you can try • Vary the frequency at which the LED is blinking • Add more LED’s
- 15. • Uno has one UART hardware port, using which we can exchange information with computer • Very useful for debugging • Works at a specified baud rate • Use Serial Monitor to read values (Tools -> Serial Monitor) • SoftwareSerial is also available http://hardwarefun.com 15 Printing values through Serial
- 16. Reading values from Serial serial.read() serial.print() serial.println() https://github.com/sudar/arduino- sketches/blob/master/SerialPrint/SerialPrint.ino
- 17. Digital Input And Output http://hardwarefun.com 17
- 20. The LED blink that we did at “setting up Arduino” is Digital output http://hardwarefun.com 20 Digital Output
- 22. • Connect the LDR on pin A0 and Gnd • LDR’s resistance varies based on the amount of light present • Read the current value using analogRead() • Print the value in Serial Monitor http://hardwarefun.com 22 Reading Analog values from sensors
- 25. • What is PWM? • Analog like behavior using digital output • Works by switching the LED on and off regularly • Changing the brightness of a Led http://hardwarefun.com 25 Analog Output
- 27. Combining Input and Output http://hardwarefun.com 27
- 28. Control an LED based on light void setup() { pinMode(13, OUTPUT); } void loop() { int val = analogRead(A0); if (val > 50) { digitalWrite(13, HIGH); } else { digitalWrite(13, LOW); } }
- 29. Things to try • Control LED based on button press • Alternate two LED’s based on button press • Persist the status of button
- 30. Moving Forward • Connect to display devices like 7-segment display or LCD • Connect to motion sensors • Connect to other components like shift register etc • Connect to a RTC chip
- 31. Things which I have tried • Connecting to mobile Android phones using – Bluetooth – Wired and wireless – Audio Jacket – NFC – ADK • Connected all sorts of display devices including VGA devices like projectors • Connected external USB devices like keyboard, mouse and even USB Missile launchers - http://hardwarefun.com/tutorials/controlling-usb-missile-launchers- using-arduino • Connected ez430 chronos watch • Connected IR devices like TV Remotes etc • Connected bluetooth devices like WiiRemote • Created small autonomous bots that can be controlled by either a WiiRemote or Android phones - http://hardwarefun.com/projects/asimi • Detect motion using PIR, IR and ultrasound motion sensors • More projects at http://hardwarefun.com
