Kan kujemput dikau sang putri, pada saatnya nanti. Berkereta kencana kubawa pergi, tujuh istana di sanaku bertahta...

Transmit serial data to an Android device, :)

Independent LEDs Blinking



 using Arduino FreeRTOS, realtime multi tasking, :)

 I programmed LED on pin 2, 3, 4 and 13 to blink at its own time. The advantage of this Arduino FreeRTOS is we don't have to calculate the timing of each pin in respect of sequential execution. It's has its own task and schedule, independent of each other.
