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 ...

I’ve been testing out the RYB2340 Bluetooth module, and it’s honestly one of the simplest ways I’ve found to add wireless ...

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

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

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

An Arduino Shield to measure an FSR using either a buffered voltage divider or current to voltage op-amp solution. We needed is an instrument that can plot the voltage/thrust curve for any motor 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 ...

Abstract: The widespread adoption of the fifth generation (5G) of cellular networks has brought new opportunities for the development of localization-based services. High-accuracy positioning use ...
