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

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

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

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

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

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 ...

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 ...

The ESP32 is a microcontroller that provides an API for Bluetooth A2DP which can be used to receive sound data e.g. from your Mobile Phone and makes it available via a callback method. The output is a ...
