Build Your Own Bicolor LED Waistband
Inspired by a dazzling Chinese design, I started thinking about making my own bicolor LED waistband with a few components lying around my workbench. In this post, you can see the basic design concept of […]
Photosensitive Hobby Servo
There are many ways to use standard hobby servos in do it yourself projects. I semi-regularly hear about design concepts that I’m not familiar with. Recently, I had a reader, who’s an amateur toy maker, […]
Tiny Bicolor LED Fader
Not all Arduino projects demand all GPIOs. ATtiny85 microcontroller certainly helps in miniaturizing such projects as required. So, for simple projects, the ATtiny85 can be a great choice. Recall that the ATtiny85 microcontroller chip is […]
Water Outflow Alarm v1
Water outflow alarms (flood sensor alarms) are arguably the most widely used commercial water leak detectors since they are cheap and easy to install. A water outflow alarm helps protect your home and belongings from […]
Simple Servo & LED Controller
Hopefully this short post will give you some practical pointers for making your own LED spotlights that also includes a servo actuator. There are dozens of different ways to drive standard hobby servos, and here […]
Automatic Shutdown Circuit for Arduino (v1)
Some time ago I had posted a couple of Arduino projects that work in conjunction with external power supply circuits. If you have not already got those ideas yet, you may simply go through the […]
Matchbox Magic Lamp v1
This post is about the construction of a multi-colored matchbox-sized magic lamp for kids using a simple and cheap microcontroller board. The most interesting thing about this build is that it does not require any […]
Arduino Spider Wrap
Spider wrap is a type of security device used by many retailers. It’s simply a wired alarm that is attached to products to prevent theft. If the wire on the spider wrap is cut, the […]
A Tiny Task Light
Ever wondered how to build a multimode task light, and how to use a single button switch to change the mode of brightness? I too was curious about it so I studied many things about […]
Build Light Indicator – Arduino Inside!
I recently got my hands on a string of COB LED modules with lens for a big project – smart driveway marker. I’m still tweaking things but I’m planning to share the project soon enough. […]
