Charlieplexing. Aside from being a fancy word it is a technique for driving multiple LEDs with relatively few pins on a microcontroller. It allows you to drive N*(N-1) LEDs with just N pins without requiring any additional hardware, making it a quick, cheap and easy way to add multiple LEDs to your arduino projects. Throughout […]

In this project, I’ll show you how to make your own 8×16 RGB LED Matrix using Arduino Uno/ Nano. An LED Matrix can show scrolling messages, display animations, music spectrum analyzer … With integrating NodeMCU, it can be used as small screen to show weather information from internet or any process values when it connect

If you’ve even seen a fake candle you have probably noticed how it doesn’t look realistic. Whether you’re trying to add some atmosphere to a dinner or light up a jack’o-lantern, your choices are limited. A real candle has a fire hazard, but a fake candle will look tacky. If only there were a safe

LEDs are designed to emit light, but they also make surprisingly capable sensors. Using only an Arduino UNO, an LED and a resistor, we will build a hot LED anemometer that measures wind speed, and turns off the LED for 2 seconds when it detects you are blowing on it. You can use this to

I made a Sunlight simulating lightbox with a mountain village skyline, that I might upgrade to a wake-up light some time, for a school project. Step 1: Get the Supplies Supplies I used: -Arduino UNO -Neopixel ledstrip 1m, 30 leds(DC5V-W2812) -3 jumper wires -USB cable type B -5V power adapter -Aluminum tape(or aluminum foil) -4mm

This is a YouTube Subscriber counter built with an ESP8266. It uses the YouTube apiv3 to poll for changes. It’s made specifically for one of my favourite youtubers Henk Rijckaert. It was featured in his livestream where the goal was to get to 9000 subscribers. Step 1: Parts Needed – Electronics and Case The project is

Let’s learn how to control multiple LEDs using Arduino’s digital outputs and a breadboard. Expanding upon the last lesson on blinking an LED, We’ll connect some LEDs to the Arduino Uno and compose a simple program to light them up in a pattern. You can follow along virtually using Tinkercad Circuits. You can even view this lesson from

The design was inspired by a product that is also presented on Instructable called “Arduino Basics with Night Light” (https://www.instructables.com/Arduino-Basics-With-…). Originally, the device is only allowed to change the LED lights by pushing down a button; after adding the codes and circuits (added: a speaker to notify the user for using recommended relatively peaceful color-blue/a

Recently I have been playing around with Arduino. Arduino is really cool and is a great way to learn electronics. In this Instructable I will teach you the basics of Arduino including: LED’s Buttons Potentiometers Resistors Tinkercad And a project with this knowledge. Step 1: The Board The controller can be broken down into a

Exactly a year ago (February 2020), James’ wife wanted to expand her plant growing setup in the house. This included a bigger, larger, taller plant growing area AND the need for more lighting. BINGO! The seed for the Idea was planted. After an exhaustive market research, not able to find the product that we had
