The built-in function analogRead() can be used to read any of the analog pins on the Arduino. However, that method blocks while waiting for the Analog-to-Digital Converter (ADC) to read the analog ...

The RetroAV shield provides the interfaces necessary to implement a simple retro style computer user interface using a PS2 keyboard for input, composite video and analog audio for output. It is ...

Abstract: Cryptocurrency mining is energy-intensive and large operations could put pressure on an already failing national grid in South Africa. This is relevant since cryptocurrency is gaining ...

Persistence of Viasion is a fundamental principle that allows our eyes to perceive continuous motion from separate images, a concept crucial to the illusion of motion in cinema. When I was a kid, I ...

I picked up some pulse width modulation to voltage converter modules. You’ve seen these before under a variety of names. They look amazing for the price, but there are a few little things you might ...

This is a useful addition to my previous article “Arduino EEPROM”. The article is still available. I have provided a link here for convenience https://www.edn.com ...

We developed a simple device to teach the concept of pH to visually impaired people through an experimental approach. An interface between a glass electrode and an open-source electronics platform ...

The MQ gas sensors can either purchased as a module or just as a sensor alone. If your purpose is to measure only ppm then it’s best to buy the sensor alone since the module is good for only using the ...

ESP32 - Digital Voltmeter using old style ADC conversion method. ESP32 - Digital Voltmeter using old style ADC conversion method. High precision, good stability , negative and positive Voltages !

Although the idea behind this project is quite straight forward, the implementation is a bit more difficult. The software may need some modification to be compatible with your DCF clock, so we have ...
