Tiny Scope for Arduino

An Isolated design for a demo board using the Analog Devices ADE9078 3 phase AC wattmeter. Design allows both WYE (STAR) and Delta (TRIANGLE) distributions to be measured along with Blondel and non-Blondel measurement schemes. The project includes a SPI based Arduino style library.

e_Lab is a modern, distributed application designed to seamlessly connect hardware data sources (such as ESP32 Arduino) with web-based user interfaces. By utilizing a decoupled architecture consisting of a Python backend and a React frontend, e_Lab provides a highly flexible and dynamic environment for hardware monitoring and control.

The Electric Circuits project implementation of a voltmeter to measure the voltage between 0 and 30 when the circuit is connected to the power supply.
