I already found very useful code to display the character with the LCD.




Happy share :)

This weekend I added up some instrument called piezo buzzer. We can play the tone, and as the beginner I started with the example from here . The copied code is here

Blink LED #Learn Arduino

Up from hello world, now we go little bit further to make the LED blinking.

Some material we need:

• Arduino (I am using Arduino UNO)
• LED
• 330 Ohm resistor
• PC/laptop
• Breadboard
• 3 jumperwire
• Data cable from Arduino to PC

This is the code, and it's available on the example of Arduino IDE Software with title "Blink"


"high" means 5V supply and make the LED is ON and
"low" meand 0V supply and make the LED is OFF.

The LED will be ON and OFF repeatedly every 1 second  that's because we put the code on the loop.

Hello World Repeated #Learn Arduino

Modifying from the previous, here I would like to make the "hello world"  appear repeatedly.

---------------------------------------------------------------------------------------------------

//Learn Arduino-Hello world Repeatedly-Hanifadinna

void setup () {
  Serial.begin(9600); //open serial port with speed 9600 bit per second
}

void loop () {
 delay(10000);  // delay time 10 second
 Serial.println("Hello world");  //print out the hello world
}
---------------------------------------------------------------------------------------------------
 Verivy, uplod and we just simply type "ctrl+shift+M" to show the print of "hello world", and then we got this from serial monitor.

To make the hello world appear repeatedly is because we put :

 delay(10000);  // delay time 10 second
 Serial.println("Hello world");  //print out the hello world

inside the void loop, so the hello world will appear repeatedly every 10 second. 

Hello World #Learn Arduino

The first time we practicing programming ussually with "hello world". Since Arduino both hardware and software, here is how to hello world in Arduino

---------------------------------------------------------------------------------------------------

//Learn Arduino-Hello world

void setup () {
  Serial.begin(9600);//open serial port with speed 9600 bit per second
  delay(10000); // delay time 10 second
  Serial.println("Hello world"); //print out the hello world
}

void loop () {}
