    How do led circuits connect to Arduino?

    The most basic LED circuit connects to Arduino as follows: The resistor is crucial for limiting current and protecting both the LED and Arduino. Let's start with the classic "Blink" example: What's happening: Let's create a simple sequence with multiple LEDs: We can create more complex patterns by manipulating the sequence:

    If you want to light an external LED with this sketch, you need to build this circuit, where you connect one end of the resistor to the digital pin correspondent to the LED_BUILTIN constant.

    1. Create the Arduino LED circuit. For this circuit we will need: Arduino board. LED (any color, I will use red). Breadboard. 220 Ohm resistor (more info on the value later on).
    2. Arduino code to power on an LED. Power on the LED with digitalWrite() Let’s start with the most simple thing. Let’s say you just want to power on the LED when the Arduino program starts.
    3. PWM functionality with Arduino LED. As for now, you’ve seen that you can control an LED with 2 states: HIGH (fully on with 5V), or LOW (fully off with 0V).
    4. Working with multiple LEDs. For now I’ve made examples with just one LED. What if you want to use several LEDs on your Arduino circuit? Arduino Circuit with 3 LEDs.
    5. Going further with Arduino and LEDs. In this Arduino LED tutorial you’ve seen how to create a circuit with a LED, and how to write code to control it. As you’ve seen, even if we keep the examples at a basic level, there are quite a few things you can do with LEDs.

    • After you build the circuit plug your Arduino board into your computer, start the Arduino Software (IDE) and enter the code below. You may also load it from the menu File/Examples/01.Basics/Blink .The first thing you do is to initialize LED_BUILTIN pin as an output pin with the line pinMode(LED_BUILTIN,OUTPUT); In the main loop, you turn the LED on...
