Programmable logic controllers are widely used in industrial automation systems to control machinery, monitor sensors, and manage manufacturing operations. Although PLCs provide reliable machine ...

Cook up some ESP32 projects this weekend.

A library that utilizes the I2C library for ATtiny85 so to control an I2C LCD screen. Largely based on the Digispark library. This library was supposed to be seamlessly working as the old ...

A simple Arduino-based project for detecting voltage and displaying the reading on a 16x2 I2C LCD in real time. The same value is also printed on the Serial Monitor for testing and verification. This ...

Abstract: The objective of this proposed system is to measure the SpO2 (oxygen saturation level) in the blood and Heart Rate (HR). The oxygen saturation level in the blood is one of the vital ...

Our team designed and built a fully functional prototype from the ground up. We handled the firmware, the PCB layout, the 3D mechanical design, and the cloud backend.

At the Hackaday Europe conference in Italy earlier in the year, we were shown a rather interesting device. The work of [Alun ...

Identifying an unmarked SMD capacitor is often a real headache: 22 pF or 220 pF? 100 nF or 1 µF? The CAP 328 was designed to ...
