Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based u-blox NINA-W102 wireless module, ...

In this video I'm showing how you can send data from an Arduino (NodeMCU) board to a hosted Laravel application. The example is super simple and I use generated random data on the NodeMCU board to ...

A lot of making goes on in this community these days, but sometimes you’ve just gotta do some old fashioned hacking. You might have grabbed an old Speak and Spell that you want to repurpose ...

Using a single GPIO port on a microcontroller to control N bits of arbitrary parallel binary outputs, e.g., a multi-digital display.

This library provides a simple way to create multiple virtual serial devices that communicate over one physical serial connection. A virtual device can be used as a drop-in replacement for Stream like ...

The heart of the sketch is Peter's algorithm for a fast ~8900Hz ADC routine along with a smoothed energy detector in 4 pass bands + 1 ZeroCrossingFrequency 'band'. Using that functionality as a ...

Abstract: Growing serial I/O data rates, over both severe low-pass electrical and dispersive optical channels, necessitate increased equalization complexity and consideration of more ...
