Arduino RGB LED configuration! That’s what we’re covering in this tutorial! Most of the time you will be using LEDs that are a single color. Red, green, or blue for example. an RGB LED is basically three LEDs in one that can produce many thousands of colors! Please note this tutorial is not about WS2812b […]
In this Arduino tutorial, we’re going to make a a circuit wherein a light sensor triggers and LED to light based on the the level of light in the room. Light sensors are actually light sensitive resistors (or photoresistors). With this type of resistor, its value resistance value changes based on the amount of light […]
To connect an LED directly in a circuit, it needs to have a current limiting resistor in series with it. Otherwise the LED will receive too much current and will fail. Use this handy LED resistor calculator to select the correct resistance for your LED circuit! LED Resistor Calculator Enter the voltage, forward voltage, and […]
In this tutorial, we’re going to show how to do the most awesome Arduino Knight Rider LEDs! It’s a highly requested article after our last update on blinking a single LED we sneak peaked this and apparently, everyone wants to know more! For those who might not know, Knight Rider is a TV show from […]
After my last video introducing the Arduino, some of you commented that you needed an example of how the Arduino works that is super simple to understand. So in this video we’re going to do the absolute simplest of projects. We’re going to be blinking an LED! Arduino: Blinking an LED Video We’ve made detailed […]
Due to many requests by our user community I’ve put together this handy list of Arduino sensors and modules. There are many, many sensors and the differences and uses of some of them can be very confusing. In this list of Arduino sensors we’ll explain what each one is used for and some quick links […]
In our last article we discussed how to wire WS2812b addressable LEDs to a Raspberry Pi. Of course, just wiring them up doesn’t really do much. Not even a single LED on a WS2812b strip will light until you send it a command to do so. So in this article we will continue on with […]
I don’t know where I have been recently, but I stumbled across one of the greatest inventions of all time recently: Addressable LED strips. Addressable LED strips, sometimes known as NeoPixels, or by various numbers such as WS2812b LED strips are LED lighting strips where each individual LED can be controlled via a specialized lighting […]
