Hardware application in Raspberry PI

i was in Depok yesterday , and suddenly thought about “how to control a hardware component by using PI”, because i used to control hardware device such as LED’S (Light emitting Diode) , Switches, censors, servos, and many more with microcontroller. maybe, i could do same thing by PI, then i searched for article last night , and i got brief tutorial. in this section, i would like to discuss hardware application and how to turn on / off your LED by using python script in Raspberry PI. this is interesting enough. here lists of my raw materials (depend on you) :

  • PI , of course
  • LED
  • Resistor , 1 x 330 ohm
  • Electronic Board or you can use breadboard
  • Cable usually called jumper to connect electronic component to others.
  • Coffee ( to enjoy step by step)

step by step :

  • create electronic circuit like this and connect it to your PI. please be carefull to make this circuit, i suggest you to use breadboard.


  • create file ‘’ :

import os; #import os to use 'system' function
import RPi.GPIO as GPIO #GPIO module to access your GPIO Port in PI
import time

GPIO.setup(3, GPIO.OUT); # 3 : port GPIO3 set as output
os.system("clear"); #clear screen
status = True; #boolean status as flag true or false, but set true first
while(status): #while status true then loop
 print "1. Nyalakan Lampu"
 print "2. Matikan Lampu"
 print "3. Kedap Kedip"
 print "0. Keluar"
 pil = raw_input( "Pilihan Anda : ") #store user input to pil variable
  print "Lampu Dinyalakan";
  print "Lampu Dimatikan";
  GPIO.output(3, True);
  for i in range(1,10):
   GPIO.output(3, False);
   GPIO.output(3, True);
  print "Terima kasih";
  status = False;
  print "GAGAL";
 raw_input("Press any button");

  • Test your PI, execute it , type sudo python .

  • After learn about fundamental of hardware of PI, it leads you into combination of hardware and software. you can put servos, censor , switch and other technique. hopefully ๐Ÿ™‚

Sophisticated Technology

never imagined before. . i am a computer science warrior . :)) . graduate from vocational school, continue to Diploma, now study at bachelor degree of Information system. yes. i like computer science, i like programming language, “Java” and “PERL” is my Favorite language. why use PERL ? because i had read article from Mr.Budi Rahardjo who wrote article about PERL programming language. he describe why he use PERL, etc. immediately i try to use PERL.. after try many function in PERL, i moved to Java. why Java ? because my friend Frizal, taught me Java. he had taught the fundamental of Java, until i can teach in laboratory.

because i like Java very much, i have a hope, to buy some books about Java, not only in Indonesia but also in foreign country. i have bought many books abroad, like at Madinah , Singapore and Malaysia. . here all of my foreign books with English subtitle. now, i must have collect some money to go abroad, buy some books . realize it!.


i believe , 3 years later or maybe a decade. computer science field still become most wanted major ever found in the world. it will overlap Doctor . believe that. and , i read a poem . who win in sophisticated technology, he will master in world ๐Ÿ˜›

Edit Data Database dengan CodeIgniter

August 5, 2012 2 comments

Setelah pada materi sebelumnya belajar seputar insert, delete dan update, sekarang saatnya kita belajar Edit Data Database dengan Framework CodeIgniter.Untuk sintak edit disini kita hanya perlu mengubah sedikit sintak insert Data. Berikut cuplikannya :


Tambahkan method berikut :

public function edit($id="")
if ($this->form_validation->run() == FALSE)
$a = $this->input->post('title');
$b = $this->input->post('content');


Berikut model dalam database :

public function edit($id,$title,$content)
$q="update news set title='$title',content='$content' where id='$id'";
return $this->db->query($q);ย  //db->query() merupakan pengambilan query


<?php echo validation_errors(); ?>
<?php echo form_open(); ?>
<input type="text" name="title" value="<?php echo set_value('title');?>" size="50" />
<textarea name="content" cols="50" value="<?php echo set_value('content');?>"></textarea>
<div><input type="submit" value="Submit" /></div>
