This Arduino based digital clock is synchronized by the 60Hz power line. It has a simple and inexpensive common anode 4 digit 7 segment display which shows hours and minutes. It uses a cross over detector to detect when the incoming 60Hz sine wave crosses the zero voltage point and derives a 60 Hz square […]

In the very early days of the PC revolution the only way to have a computer was to build one, sometimes from a kit but often from scratch. For the young, impoverished hobbyist, leafing through the pages of Popular Electronics was difficult, knowing that the revolution was passing you by. And just like that, the days of

[Andrew] wonders why the SerialUSB() function on the Cortex M3-based Arduino Due is so much faster than Serial() on the Uno or Nano, and shares his observations in this short video. He sets up an experiment with a simple sketch on both boards and uses Wireshark to evaluate the results. Data is sent in the USB packets in groups of

To get started with Arduino, you’ll need some basics. In this tutorial, we’ll go beyond a little blinky light and teach you about: Variables Input and Output pins Sensors and reading data Mapping results Functions In another tutorial, I’ll cover classes and why we might use them. But, we might still make a little light
This weekend marked the 49th anniversary of the legendary Intel 4004 microprocessor, and to celebrate [Erturk Kocalar] combined the old and new in this intriguing Retroshield 4004 / Busicom 141-PF calculator project. We have reported on his Arduino shield project before, which lets you connect a variety of old microprocessors to an Arduino so you can experiment with these

I am the theatrical technical director for a local high school. Their winter production was “Disney’s High School Musical”. During meetings with the director, he said it would be cool if he could have a scoreboard. I excitedly replied that I could make one that worked by remote control. Warning: be careful what you promise.

[Noteolvides] creates the CubeTouch, a cube made of six PCBs soldered together that creates a functional and interactive piece of art through its inlaid LEDs and capacitive touch sensors. The device itself is connected through a USB-C connector that powers the device and allows it to send custom keyboard shortcuts, depending on which face is touched.
