Embeded Programing

1. Learning the basic of computer

2. Setting up Auduino

3. code example

void setup() {
 Serial.begin(115200);
 Serial.println("Hello, world!");

}

void loop() {
 tone(40,400,600);
 delay(800);
 tone(46,400,600);
 delay(800);
 tone(46,440,600);
 delay(800);

 tone(40,400,600);
 delay(800);
 tone(46,400,600);
 delay(800);
 tone(46,440,600);
 delay(800);

 tone(40,400,600);
 delay(800);
 tone(46,400,600);
 delay(800);
 tone(46,440,600);
 delay(800);

}

1. Connect buzzer to Arduino Board

Ground-negative, pin-positive

Board pinout:

Pinout - Barduino Documentationfablabbcn-projects.gitlab.io

1. How to read the voltage on a bit

add LED to arduino: long leg-positive

connect resistor to LED

`electricity flow from high(positive) to low(negative)

void setup() {
 Serial.begin(115200);
 Serial.println("Hello, world!");

 pinMode(2,OUTPUT);

}

void loop() {
 
 digitalWrite(2,HIGH);

 delay(400);
 Serial.println("Hey!");
 delay(400);
 Serial.println("Zeeee!");
 tone(50,440,500);
}

1. exercise: Turn on the programmable LED on Barduino (pin 48), ON for the "S"s, OFF for the "O"s

void setup() {
 Serial.begin(115200);
 Serial.println("Hello, world!");

 pinMode(48,OUTPUT);

}

void loop() {
 
 digitalWrite(48,HIGH);
 //digitalWrite(48,100);
 Serial.println("S");

 tone(46,400,600);
 delay(800);
 tone(46,400,600);
 delay(800);
 tone(46,400,600);
 delay(800);

 digitalWrite(48,LOW);
 Serial.println("O");

 tone(46,440,200);
 delay(400);
 tone(46,440,200);
 delay(400);
 tone(46,440,200);
 delay(400);

 digitalWrite(48,HIGH);
 //digitalWrite(48,100);
 Serial.println("S");

 tone(46,400,600);
 delay(800);
 tone(46,400,600);
 delay(800);
 tone(46,400,600);
 delay(800);

 delay (800);

}
