The loop function runs as long as the Arduino board is powered and will blink the LED ON and OFF withe 1 second pause between states. You can use another pin, for example pin 12 and then change the ...

Blinking an LED is one of the first steps to understanding how to interact with hardware using Arduino. This example uses the onboard LED, which is usually connected to pin 13 on most Arduino boards, ...

Setup 1. Run Arduino. 2. Open the LED blink example sketch: File > Examples > 1.Basics > Blink. You should see a window like in Figure 2. 3. Choose Tools > Board, then select your board, like in ...

You could put the Arduino in deep sleep, if you wanted to and that LED will still blink. With a little work, you could probably adapt this idea to any number of circuits out of the 555 playbook ...

This program modulates a sine wave with PWM to fade in/out the onboard LED on Arduino UNO ATmega328P's PB5 PIN which can not be used with hardware PWM The program is not efficient as the <math.h> ...

It is a pretty common first project to use an Arduino (or similar) to blink an LED. Which, of course, brings taunts of: you could have used a 555! You can, of course, also use any sort of oscillato… ...
