On the face of it, making a clock that displays the time by moving a pointer along a linear scale shouldn’t be too hard. After all, steppers and linear drives should do the job in a jiffy. Throw an Arduino in and Bob’s your uncle, right? Wrong. At least that’s not the way [Leo Fernekes] […]

Introduction Arduino is an open-source microcontroller, which has positively influenced the education field and time management for students. It operates a specific program to perform a specific task. Arduino software helps students schedule their study year and improve the quality of education, along with several other learning benefits.

It is a truth universally acknowledged that a single cat in possession of good fortune must be in want of a laser toy. As with single gentlemen in want of future wives, some precautions must be observed. But is that not true of anything really worth having? If you do have concerns about pets and
This is a creative cylindrical LED cube with proximity sensing by infrared led and photo-transistors. Interactive Cylindrical Cube includes: 8X8 royal blue LEDs, 12 infrared LEDs, 16 photo-transistors and all of them are bent & formed a cylindrical shape. Please see video below when this interactive cylindrical cube is used as flowerpot. Step 1: Bill

Zener Diode Tester is controlled by Arduino Nano. Tester measure breakdown Zener voltage for diodes from 1.8V to 48V. Dissipation power of measured diodes could be from 250mW to a few Watts. Measuring is simple, just connect diode and press button START. Arduino Nano gradually connect range of voltages from lower to higher, in four

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

In this project I will show you how I combined an Arduino Nano, a current sensor, an LCD, a rotary encoder and a couple of other complementary components in order to create an adjustable constant load. It features a constant current and power mode and can handle a maximum of 30V and 20A if your

Definition A current clamp is an instrument used to measure the number of amperes passing through a conductor. The electrical device comes with jaws that open when brought close to the electrical conductor to allow it to clamp. This feature eliminates the need for the current clamp to make physical contact with the current-conducting wire

What do you give a six-year-old who loves going fast but doesn’t like loud noises? Convert a gas go-kart to electric of course! (Video, embedded below.) That goal started [Robert Dunn] of Aging Wheels down a long path toward a go-kart that almost, but doesn’t quite… work. If you’ve watched any of [Robert’s] videos, you know
