Optocouplers frequently fail without a sound in labs or during repairs. The package appears to be undamaged, but there may be no output from the LED source or the photosensitive output stage. Testing ...

Abstract: This paper investigates LED bulb dimming technology, specifically focusing on leading-edge phase control methodology. A hardware circuit was designed and implemented to evaluate the ...

Over the last decade, the open-source movement has not only transformed the world of software, but also catalyzed a sweeping revolution in hardware tinkering. At the heart of this shift lies a ...

Abstract: This paper presents a real-time hardware testing design based on a hybrid approach between Flying Probe-Inspired In-Circuit Testing (FPICT) and Joint Test Action Group (JTAG) debugging ...

Waveshare “ESP32-S3-Touch-LCD-4.3B” is a capacitive touch display development board built around an ESP32-S3 SoC with RS485, CAN Bus, I2C, and isolated DIO interfaces provided through a terminal block ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Learning electronics? Then, chances are you already know what an Arduino is, or at the very least, you've heard of it. After all, it's among the most popular electronics platforms available in the ...

Switching power supplies, operating directly from input power lines, are generally required to have their outputs galvanically isolated from the input, in order to reduce the danger of electrical ...
