Some people can’t be bothered to read the analog face of a traditional clock. Some people cannot stand the low frequency “hum ...

I often ask people: What’s the most important thing you need to have a successful fishing trip? I get a lot of different answers about bait, equipment, and boats. Some people tell me beer. Bu… ...

Firmware for the DIY WiFi-Controlled Drone The firmware from our DIY drone is based on the ESP-drone firmware from Espressif. The code is written with ESP-IDF, and the version that is used to compile ...

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 ...

In this comprehensive TMC2209 Arduino tutorial, we'll walk through a complete example of how to interface a Bigtree Tech TMC2209 stepper motor driver with Arduino UNO for precise directional rotation ...

This paper proposes a single-phase grid voltage fundamental frequency estimation technique for smart meters. The technique relies on a nonlinear Newton-type algorithm and a recursive differentiation ...

The meter is based entirely on basic digital circuits and does not include a microprocessor. A large-capacity ROM is used to convert the data, which are proportional to the line period, into line ...
