The document provides an overview of Arduino, an open-source hardware and software platform based on AVR microcontrollers and C programming, highlighting its various features such as inbuilt ADC, PWM, and easy programming. It includes programming basics, example code for LED control and button interfacing, and exercises for practicing with LEDs. The content covers introductory concepts, programming functions, and practical applications like LED blinking and button handling.
Arduino Day 1 Presentation
- 2. INTRODUCTION TO ARDUINO - Open Source Hardware and Software Platform -Self Contained Computer in an IC INTEL 286 Arduino Diecimila
- 3. INTRODUCTION TO ARDUINO - Based on AVR microcontrollers that are widely popular for their RISC architecture, hight flash memory, inbuilt different features - Arduino Uses C programming(E A S Y)……
- 4. WHY ARDUINO? - Inbuilt ADC, Serial Interface, PWM, IO pins -Programming so easy……(Can be used available libraries) -Open Source platform
- 5. HARDWARE I/O PORTS ========== 14 PWM ========== 6 Analog ========== 6 8 bit =======256 10 bit ======= 1023 ADC
- 8. SOFTWARE REQUIREMENTS Arduino IDE Serial Port Driver
- 9. ARDUINO PROGRAMMING BASICS Void setup() { //your initialization code } GLOBAL Variables 1. 2. Void loop() { //your repeating code } 3.
- 10. int ledInput=13; //pin 13 is ledIput EXAMPLE:
- 11. Example void setup() { Serial,begin(9600); //serial port baudrate=9600bps pinMode(ledInput, output); // configure pin 13 as output port }
- 12. void loop() { digitalWrite(ledinput, high); //led=on delay(500); digitalWrite(ledinput, low); //led=off delay(500); }
- 13. Functions used in setup()1. pinMode(13, OUTPUT); makes pin 13 as output pin 2. pinMode(8, INPUT); makes pin 8 as input pin 3. Serial.begin(9600) ; starts serial communication with Baudrate 9600 Functions used in loop() 1. digitalWrite(13, HIGH): makes pin 13 high ie pin13=ON; 2. delay(500) : delays system by 500 ms. 3. analogRead() : Reads analog value 4. analogWrite() : writes anlog value(PWM) 5. Serial.print() : Prints at serial monitor 6. Serial.println() : prints at serial monitor with line break
- 14. EXERCISE: Write the code and implement: 1. One led blinking at each 1s. 2. A led with ON time=600ms and OFF time=900ms 3. You are given 6 leds. Now light these leds in different patterns
- 15. int ledPin = 13; // choose the pin for the LED int inPin = 2; // choose the input pin (for a pushbutton) int val = 0; // variable for reading the pin status void setup() { pinMode(ledPin, OUTPUT); // declare LED as output pinMode(inPin, INPUT); // declare pushbutton as input } void loop() { val = digitalRead(inPin); // read input value if (val == HIGH) { // check if the input is HIGH (button released) digitalWrite(ledPin, LOW); // turn LED OFF } else { digitalWrite(ledPin, HIGH); // turn LED ON } }
- 16. --What is debounce ? --Bistable Switch
- 17. REVIEW: ARDUINO INTRODUCTION ARDUINO PROGRAMMING LED BLINKING BUTTON INTERFACING
