This LED module is of high brightness because the lamp beads it carries is 3w. We can apply this module to Aduino projects. For example, intelligent robots can use this module for illumination purpose.
Please note that the LED light can't be exposed directly to human eyes for safety concerns.
// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin 13 as an output.
pinMode(13, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(13, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(13, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
