Communication between multiple controllers is almost a must when it comes to large projects. So, in this Lab we’ll investigate in brief the use of the atmega32L, PIC16F877a and the Arduino Uno in some ...

This is a very simple but useful project, strobe navigation lights for rc airplanes, or you can adjust the flashing time and make it a warning light for a forklift or even a turn signal light for a ...

There's no shortage of budget-friendly TVs on the market these days. That said, if you're looking for the best cheap TV brand according to customer satisfaction, you should be shopping for a Hisense ...

Crowbar circuits have long been the go-to safeguard against overvoltage conditions, prized for their simplicity and ...

Here we describe an electronic system that uses a dedicated water-level sensor to switch off the pump motor as soon as the ...

There's a lot of confusion surrounding the law for bike lights: is a flashing light legal or does it have to be steady? And do you have to fit reflectors, too? Here, we set the facts straight. It's ...

A blast from the Elektor archives: this clever 1998 battery tester uses a simple LED display to reveal a battery’s true condition under load — even below 1 V. Built from standard components and no ...

Abstract: In this paper, a single-stage LED driver is proposed for a street lighting system. Two boost circuits that share a single inductor are formed by integrating the switches of a half-bridge LLC ...

Abstract: In this paper, two LED emitting circuits are implemented in a VLC positioning system, a regular Bias-Tee and a circuit proposed by Ghassemlooy, aiming to provide the system with portability ...
