Arduino has just announced the Arduino Matter Discovery Bundle (AKX00081), an all-in-one development kit designed to help ...
A simple audio visualizer that maps the audio signals from ADC to LED strip. The number of lit LEDs is based on the amplitude of the audio signal, with a brighter peak indicator on the highest ...
Abstract: In this study, we propose a novel design scheme for high-precision frequency meters based on a combination of microcontroller and FPGA technologies. Traditional frequency meters often face ...
Abstract: Strong electromagnetic interference affects the normal operation of smart meters. This paper analyzes the corresponding mechanisms of electromagnetic interference and establishes an ...
