In this Arduino beginners tutorial you learn yow to use a breadboard, what a LED is, how resistors work and how you can make a fading LED. The resistor calculator is located at https://www.digikey.de/en/resources/conversion-calculators/conversion-calculator-resistor-color-code-4-band
- Build the Circuit. Take a look at the circuit in the workplane. The rows of a solderless breadboard are connected inside, allowing you to connect components by plugging them into the same row as each other.
- Code With Blocks. Let’s use the code blocks editor to create an animation effect. Click the "Code" button to open the code editor. Click on the variable category in the code editor.
- Animation Arduino Code Explained. When the code editor is open, you can click the dropdown menu on the left and select "Blocks + Text" to reveal the Arduino code generated by the code blocks.
- Build a Physical Arduino Circuit (Optional) To program your physical Arduino Uno, you'll need to install the free software (or plugin for the web editor), then open it up.
Jan 6, 2020 · Step 1: Place the LED sensor in the breadboard. Step 2: Connect one pin to the A0 (analog pin) of Arduino, and connect another pin to the GND pin of Arduino. Step 3: Place another LED on a breadboard and connect a 220-ohm resistor to its Anode. Step 4: Connect a wire from the resistor to pin 13 on Arduino (digital pin). Connect the Cathode of ...
- 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).
- 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.
- 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).
- 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.

Plug your LEDs into any two rows on the breadboard with the long leg (positive) toward the top of the breadboard. Connect a jumper wire from the positive leg of each LED to the Arduino pins. In the example, pins 13, 12, and 8 are being used.
Using the breadboard, connect the negative leg of each LED to a ground pin on the Arduino board.
