Introduction
Linker LED Module is designed for the beginners of Arduino/pcDuino to monitor controls from digital ports. It can be mounted to the surface of your box or desk easily and used as pilot lamp for power or signal. Its brightness can be adjust by potentiometer.
Application Ideas
test <syntaxhighlight lang="c"> /*
Blink Turns on an LED on for one second, then off for one second, repeatedly. This example code is in the public domain. */
void setup() {
// initialize the digital pin as an output. pinMode(13, OUTPUT);
}
void loop() {
digitalWrite(13, HIGH); // set the LED on delay(1000); // wait for a second digitalWrite(13, LOW); // set the LED off delay(1000); // wait for a second
} </syntaxhighlight>
