Since we all know how a LED works and what all can be done with it let us start the tutorial.
For those of you who are new kindly refer our previous blogs to explore LEDs.
Components required
- Led 1No.
- Arduino UNO 1No.
- Few connecting wires.
The circuit connection is very simple just connect the anode of the Led with the 11th pin of Arduino and connect the cathode with the ground.
After making the connections dump the code given below.
int i;void setup()
{
}
void loop() {
for (i = 0; i < 256; i++)
{
analogWrite(11, i);
delay(10);
}
for (i = 256; i >0 ; i--)
{
analogWrite(11, i);
delay(10);
}
}
void loop() {
for (i = 0; i < 256; i++)
{
analogWrite(11, i);
delay(10);
}
for (i = 256; i >0 ; i--)
{
analogWrite(11, i);
delay(10);
}
}
