Shoving all your home theatre device into a single cabinet makes sense when you want to keep your living room neat and tidy. But there’s just one (usually overlooked) problem – overheating. Yes, with a […]
Happy Xmas is near, so it’s time to build your own festive lights to surprise your neighbors. In this post, you will learn how to make Christmas special LED pixels with Raspberry Pi Pico! First […]
This is an update to an old project of mine that was printed almost a decade ago! Here is the link to that little nostalgic project https://www.electronicsforu.com/electronics-projects/portable-signal-wand At this point, I’m using a microcontroller as […]
After posting the Backpack NeoPixel LED Safety Light project (https://www.codrey.com/arduino-projects/backpack-neopixel-led-safety-light/), I received a lot of requests to publish another do it yourself project based on regular light-emitting diodes, instead of using NeoPixel LEDs. So, I […]
This little post covers the construction details of sound reactive pixels which is pretty enjoyable to build and watch. You can embed it in a lot of things, for example, think about gluing it in […]
After a little bit of research, I discovered that building a portable ultrasonic distance meter using Arduino was indeed a very simple task. I was surprised to discover that integrating a tiny OLED display into […]
This article shows you how to use reverse voltage protection with minimal power loss in your electronics projects running on a battery/DC power supply. In fact, for a long time, I wanted to put together […]
We’ve controlled electrical appliances through a number of wired and wireless control methods. That’s okay but how about controlling them with the alarm signal of a cheapo quartz table clock? This article demonstrates the simple […]
Looking for a simple way to make your own automatic LED lamp for your staircases or corridors? This simple self-timing LED lamp gives you a defined light output at the exact time you need it. […]
A while ago, I designed a Power MOSFET Load Switch circuit using a handful of components that I use in little power electronics projects to allow a regular slide switch to control power on/off function. […]
