From a simple electronic toothbrush to complicated robotics systems, DC motors are present everywhere. In most of our previous Arduino projects, we have used these DC motors as actuators and ...

Is it possible for a tiny microcontroller to run on a hefty 48-V battery? This project makes it happen using a custom step-down converter — and along the way, it uncovers some surprising design ...

We’ve seen LCDs with touch input before, but what if the LCD itself could be used as a touch sensor? That’s exactly what YouTuber CNLohr has accomplished with his latest project, combining a 7-segment ...

Abstract: This paper describes development of a radio receiver that was designed as a personal computer (PC) plug-and-play peripheral device. The radio is capable of receiving FM signals in a standard ...

Until recently, a very common problem faced by electronic circuit designers was the difference in supply voltage standards between microcontrollers (e.g. 3.3 V) and peripheral ICs (e.g. 5 V). In order ...

This circuit is useful to detect a voltage drop in a constant signal getting noisy, by detecting and react fast to edge falling signals. The circuit components allow to define the voltage drop ...
