Let us first design a smart led blinking system which will blink how we want it to, sounds fun right.
So let’s begin
So let’s begin
Components Required
- Resistor 1No. 330ohms (Standard Red LED and 5V Input)
- Led 1No.
- Arduino UNO 1No.
- Few Connecting wires
- Breadboard
Follow the below video for circuit connection reference:
Now since we have made the circuit let us do the coding part
// declare the pin to which LED is connected:
int led = 5;
//The below is the setup block the part which we want to run only once we declare them in this block
void setup() // initialize the digital pin as an output.
{
pinMode(led, OUTPUT);
}
void loop() //The code we write inside void loop runs over and over again in loop :
{
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
We can introduce delay according to our need Arduino IDE takes values in milliseconds inside the function delay, in the above code 1000 means a delay of 1 sec so if you want to increase or decrease the delay change the values accordingly. You can also use the function delayMicroseconds() if you want to give input in microseconds.

- Arduino has an inbuilt Led at Pin no.13
The digital pin no. 13 of UNO is actually the 5th pin of port B (Atmega328 IC).
Which we have mapped using the boot-loader firmware.
- You can connect a LED at digital pin no.13 of UNO without any resistor.
