In this guide, you’ll learn how to control an RGB LED using the Arduino. An RGB (Red-Green-Blue) LED can produce a wide variety of colors by mixing different intensities of red, green, and blue light. You’ll learn to create a basic Arduino RGB LED circuit and cycle through some basic colors as an example.
Using the provided schematic and breadboard images, as well as the example code below, you should have everything you need to easily set up and control an RGB LED’s color output on your own.
There are two types of RGB LEDs: Common Anode and Common Cathode. We’ll provide example schematics and code for both types below.
In this tutorial, we’ll guide you on how to set up a thermistor with Arduino to create a basic thermometer. The schematic, breadboard illustration, and example code provided will make it easy and straightforward to get your thermistor working.
Our thermistor has the following parameters:
This Arduino Light sensor circuit is a simple example that shows you how to connect light sensors such as photoresistors, photodiodes, and phototransistors, to an Arduino.
In this quickstart guide, you’ll learn how to connect a photoresistor to an Arduino board and read out the voltage. You’ll first use the Serial Monitor to learn about how the light sensor behaves, then you build a circuit that automatically turns on a light when it gets dark.
This is a great practice circuit when you’re learning Arduino. The code is straightforward and the light sensor connections are simple.
* A photodiode or phototransistor will also work.
This Arduino button circuit is a simple example that shows you how to connect buttons to an Arduino.
In this quickstart guide, you’ll learn how to connect a button to an Arduino board and read a HIGH or LOW depending if the button has been pushed or not. You’ll use the Light-Emitting Diode (LED) that is included on the board to turn on and off with the button so that you can verify that your button press code is working properly.
This is a great practice circuit to build as you’re learning Arduino. The code is straightforward and the connections are simple.
To connect a button to an Arduino, you’ll need a pull-down or a pull-up resistor. This is to make sure that when the button is not pushed, it has a defined value. In this example, we’re using a pull-down resistor of 10 kΩ.
This Arduino Potentiometer circuit is a simple example that shows you how analog inputs work, and how you can use the Serial Monitor to learn about what is going on inside the chip.
In this quickstart guide, you’ll learn how to connect a potentiometer to an Arduino board and read out the voltage. This is a great practice circuit when you’re learning Arduino. The code is straightforward and the potentiometer connections are simple.
To connect a potentiometer to an Arduino, connect the middle pin of the potentiometer to an analog input pin on the Arduino. Then connect the outer pins to 5V and GND.
Arduino is a microcontroller board that makes it really easy to program electronics. It’s an easy way to get started with microcontrollers that I highly recommend since it lets you jump right into the code and do stuff from the start.
You can use it both for building simple things like a blinking LED – and advanced stuff like building an internet-connected robot. With Arduino, it’s simple to build really cool electronics projects without learning a bunch of theory. And it’s fun!
It has several inputs and outputs that are controlled by simple commands that you write into a program on your computer.
The Arduino blink LED circuit is a simple circuit that works great for starting to learn Arduino. Both the code and the connections are straightforward so that you can understand it with little to no background.
In this quickstart guide, you’ll learn how to connect an LED to an Arduino board and make it blink.
To connect an LED to an Arduino, you need a resistor in series with the LED. This is to limit how much current the LED pulls out of the Arduino pin. The value isn’t crucial but should be between 220 Ω and 1000 Ω.
