Kesetimbangan

Dua bulan lalu di dinding kamar mandi mulai ada beberapa serangga seperti laron tetapi berukuran kecil,  sedikit lebih besar dari nyamuk. Semakin hari semakin banyak.

Tidak bisa diusir, disemprot pakai obat nyamuk pun tidak mati. Sampai saya membakar obat nyamuk di dalam kamar mandi pagi hari sebelum ngampus. Sorenya mereka tetap berada pada tempatnya, ckckck.

Sebulan yang lalu, mereka mulai berkurang, malah agak drastis. Tanpa diapa-apakan. Awalnya penasaran, apakah memang mereka pindah tempat atau yang lain. Sudahlah, yang penting mereka berangsur-angsur hilang.

Sampai suatu malam, tengah malam, ketika kebelet pipis. Di kamar mandi sedang ada sekitar lima cicak yang sedang berpesta pora, makan si serangga tadi. :)

Sekarang jadi suka senyum kalo lihat cicak-cicak gendut malas-malasan di dinding saat mandi pagi, :)

Motivasi.

Ndak usah dipaksa maju jika tujuannya ada dibelakang.

If you think you are too small to make a difference, try sleeping with a mosquito.

Alfa: Ayah, tadi jatuh pas naik sepeda gajah, berdarah. Ndak mandi, nanti perih.

Kangen.

Kinanthi: Lama nggak ngobrol ya Meg.

Meg: Iya Kin, lha sekarang semua sibuk ngurusi Mukidi.

the code is same as here

Independent Wireless Multitasking LEDs blink using Arduino FreeRTOS

and send the data wirelessly using bluetooth module HC-05. :)

The code
#include <Arduino_FreeRTOS.h>
#include <SoftwareSerial.h>
SoftwareSerial mySerial(10, 11); // RX, TX

int n = 0;

// define two tasks for Blink & AnalogRead
void TaskBlink( void *pvParameters );
void TaskBlink2( void *pvParameters );
void TaskBlink3( void *pvParameters );
void TaskBlink4( void *pvParameters );
void TaskTadaa( void *pvParameters );

// the setup function runs once when you press reset or power the board
void setup() {
   // initialize serial communication at 9600 bits per second:
  mySerial.begin(9600);  

  // Now set up two tasks to run independently.
  xTaskCreate(
    TaskBlink
    ,  (const portCHAR *)"Blink"   // A name just for humans
    ,  128  // Stack size
    ,  NULL
    ,  2  // priority
    ,  NULL );
  xTaskCreate(TaskBlink2,(const portCHAR *)"Blink2",128, NULL,2,NULL );
  xTaskCreate(TaskBlink3,(const portCHAR *)"Blink3",128, NULL,2,NULL );
  xTaskCreate(TaskBlink4,(const portCHAR *)"Blink4",128, NULL,2,NULL );

  xTaskCreate(
    TaskTadaa
    ,  (const portCHAR *) "Tadaa"
    ,  128 // This stack size can be checked & adjusted by reading Highwater
    ,  NULL
    ,  1  // priority
    ,  NULL );

  // Now the task scheduler, which takes over control of scheduling individual tasks, is automatically started.
}

void loop()
{
  // Empty. Things are done in Tasks.
