The hardware was assembled by connecting the Arduino UNO R4 WiFi, the PZEM 004T, the current transformer, and the OLED ...

Drones are widely used across several fields, including aerial photography, surveying, inspection, agriculture, and ...

An LM555 timer paired with an NTC thermistor makes a simple, configurable ON/OFF thermostat for heating or cooling.

In part 3 of this series, we used Kirchhoff’s voltage law to derive the branch currents and node voltages for an unbalanced ...

Batteries are notoriously difficult pieces of technology to deal with reliably. They often need specific temperatures, charge ...

It’s one thing to learn about transmission lines in theory, and quite another to watch a voltage pulse bounce off an open connector. [Alpha Phoenix] bridges the gap between knowledge and ...

Abstract: The paper regards a new active resistor for ultra-low power applications. Thanks to the chosen topology, based on feedback and operational amplifier, it allows to accurately emulate the ...
