Tut 2 : Blinking LED

A program to blink LED red and green on SK40C board. The delay time is set to 1 second. The blinking will repeat continously.

 

LED and current limiting resistor

LED has two ends an anode and a cathode. Connect it properly to a power supply voltage. The diode will emit light. Depending on any power supply voltage, you need to discard the current through a current limiting resistor to protect LED from burning.
