 += Overview =
 +the red LED is on for 2 sec, then the red LED is off and the yellow-green LED is on for 2sec, then it is off. this sequence is repeated.
 +Two-color LED flashes alternately. through,the LED driving principle and the basic ADK, ADK IO can know how to use.

 +== Dual Color LED ==
 +A light-emitting diode (LED) is a semiconductor light source.
 +The following ​ Mechanical diagram three different lengths of lead will be able to see that. 
 +The longest lead is Cathode of common and the next longest is the anode of the red and It is the shortest, yellow-green of the anode.

 +== Resistor ==
 +Restricts the amount of current that can flow through a circuit.

 += Circuit =
 += Schematic =
 +LED는 정전압 소자이므로 정격 전류 이상의 전류를 공급 할 경우 수명이 감소하거나 파손 될 수도 있습니다. ​
 +LED의 양극에 직렬로 저항 330옴을 직렬로 추가하여,​ 10mA 이상의 과전류가 흐르는 것을 방지하므로,​ LED를 보호 할 수 있습니다. ​
