In this guide, we will create a simple and precise digital clock using the Raspberry Pi Pico RTC DS3231 Module through the Arduino IDE. We will use a 16x2 I²C LCD screen to display the information.

Here’s something fun from [Chad Kapper] over on HackMakeMod: Escape Room Lockbox with the Cheap Yellow Display. You may have heard of the “cheap yellow display” (CYD), so-called due to the board’s ...

We’ve seen a few H-bridge circuits around these parts before, and here’s another application. This time we have an Old Train Station Clock which has been refurbished after being picked up for cheap at ...

This project utilizes an Arduino Uno CH340G development board paired with a DHT11 temperature and humidity sensor to create a compact yet capable environmental monitoring system. It measures ambient ...

Developed by Kaled Souky in 2025, the vs1053_avr_renesas_uno library is an Arduino port of the vs1053_SdFat library, originally created by Michael P. Flaga in 2012. The vs1053_avr_renesas_uno library ...

Abstract: This paper introduces a Hand Gesture Recognition System using OpenCV and deep learning to improve the interactivity between human and computer. The system uses a video feed to recognize and ...

Abstract: This paper investigates strategies for optimizing electricity usage by reallocating peak demand periods. Various techniques such as dynamic pricing, Demand-Side Management (DSM) and Energy ...
