AVR8js – Open Source Arduino Simulator Based on JavaScript
https://www.electronics-lab.com/avr8js-open-source-arduino-simulator-based-javascript/
One of the things I love about JavaScritpt is the fact it keeps finding applications in different domains. One such use is in Arduino, with Espruino (open-source JavaScript interpreter for microcontrollers), and an interesting new one is the AVR8js. AVR8js is an open-source Arduino simulator based on JavaScript that can run in the cloud or […]
Stereo volume and balance control with Rotary Encoder using MAX5440
https://www.electronics-lab.com/project/stereo-volume-and-balance-control-with-rotary-encoder-using-max5440/
The project described here is a compact stereo volume and balance control with rotary encoder. It provides 32 log potentiometer steps with buffered wiper output. The project can easily replace mechanical potentiometer. 5 LEDs indicate the volume level or balance settings , depending on the status of the mode indicator D1 LED. The MAX5440 includes […]
AC Inductance and Inductive Reactance
https://www.electronics-lab.com/article/ac-inductance-inductive-reactance/
Introduction In the previous tutorial concerning AC resistance, we have seen that the behavior of a resistor is the same in DC or AC regime under normal frequencies. However, other basic electrical components such the inductor, strongly depends on the frequency of the AC signal. A presentation of the concept of inductance is given in […]
