A Binary Clock! I was recently looking at some binary clocks and I felt like Why not? I have everything to make one and I don’t have a clock in my room. So I decided to build one and here it is. Hope you Like it and maybe build your own. It’s a cool project
Introducing the RainBoard: A simple RGB LED Rainbow fader using an Arduino Uno and a few simple components. Believe it or not, we will control 45-channels of RGB LEDs at 32 brightness levels using only 3 digital pins from the Arduino! How is this possible you ask? By using two magic concepts: Shift Registers, and
Hello everyone, and welcome to my Instructable! This instructable will show you how I made the first ever DIY Arduino controlled “LED Kaleidoscope”! What is an LED kaleidoscope? Well, our traditional kaleidoscopes used 3 mirrors joined as a triangle with stuff like sequins and stolen cake decorations at one end, to create an awesome pattern

Description MAX44000 combines a wide-dynamic range ambient light sensor with an integrated infrared proximity sensor, making it a perfect solution for touch-screen portable devices. MAX44000 consumes as little as 11µA (time averaged) in ambient light sensing plus proximity sensing, including external IR LED current. The on-chip ambient light sensor is capable of wide dynamic range
Ambient light includes IR sensor for mobiles proximity detection Continue Reading
The NanoPi R2S, which was recently launched by FriendlyElec back in January of this year, was an upgrade to the NanoPi R1S. At the time of the Nano Pi R2S publication, the board wasn’t available, and there wasn’t any information about the pricing either. As of now, FriendlyElec has fully launched the NanoPi R2S and is available for purchase starting from
FRIENDLYELEC NANOPI R2S IS NOW AVAILABLE FOR PURCHASE FROM $22 Continue Reading
Have you ever wanted to control electronics with your smartphone? The Arduino ADK (Android Development Kit) is the Arduino Mega with a built in USB host device, ready for your smartphone to be plugged in! We’ll make a simple introductory project with a few LED strips and a relay (to control the high voltages of
