What happens when you combine an Arduino-based microcontroller with a palm-sized aluminum box and clicky buttons? A fidget ...
Abstract: Secondary frequency control systems, such as Automatic Generation Control (AGC), are used in interconnected power grids. However, when a system failure causes systems to separate into zones ...
Abstract: The increasing integration of renewable energy into hybrid power systems (HPS) introduces significant uncertainties, posing challenges to frequency control. Additionally, packet dropouts in ...
I’ve encountered a limitation when using PWM on the RP2040 with the Mbed-based Arduino core: It seems impossible to set a PWM frequency below ~500Hz. This effectively restricts the usable PWM range, ...
Audio frequency detection is the process of identifying the pitch or dominant frequency of a sound signal. Three common methods used are Fast Fourier Transform (FFT), AutoCorrelation, and ...
Black screens, silent radios and near misses: Air traffic control outages are not isolated to Newark
Years before recent communications blackouts led to widespread chaos at Newark Liberty International Airport, air traffic controllers and pilots around the country repeatedly reported equipment ...
