Mengukur Temperatur dengan Sensor LM35 dan Arduino

Sensor temperatur LM35 merupakan IC (integrated circuit) sensor yang digunakan untuk mengukur temperatur yang setara dengan output tegangan yang diberikan. Data suhu akan dibaca melalui pin A0 pada Arduino kemudian diproses oleh internal Analog Digital Converter (ADC) pada Arduino. Nilai tegangan yang terbaca adalah dari 0 hingga 5 V.
Tegangan output yang dihasilkan ini akan dikonversi dengan faktor konversi temperatur sederhana. Nilai pembacaan sensor adalah dalam derajat celcius yang dirumuskan sebagai berikut:

Tc = Vout .(100 ◦ C/V )

Maka jika Vout bernilai 1 Volt keluaran yang akan dihasilkan oleh sensor ini adalah 100◦C. LM35 memiliki sensitivitas 10mV/◦C

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




Happy share :)

Controlling the LED Brightness

Finally I can go up from blink to another basic of Arduino. In this circuit we can control the brightness of LED with potentiometer.LED brightness is determined from the position knob on the potentiometer.

Some material we need:

• Arduino (I am using Arduino UNO)
• LED
• Potentiometer 10K ohm
• 330 Ohm resistor
• PC/laptop
• Breadboard
• 6 jumperwire
• Data cable from Arduino to PC 

 Here is the code that we can simply copying from Arduino IDE example:


the new things we learn in here is "sensorPin =A0". It means that we select the input pin for the potentiometer. To read the value from the sensor we just type "sensorValue = analogRead(sensorPin);"  inside the loop.

Blink LED pada 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.

How To Hello World Repeatedly in Arduino

Modifying from how to hello world in Arduino, 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 pada 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 () {}
