The LED Pattern Door Lock System is an interactive electronic project built with an Arduino Nano and a 0.96″ I²C OLED display. The system allows users to unlock a virtual “door” by entering a ...

This repository contains a complete and well-documented digital clock built using an Arduino Uno or Arduino Nano, a DS3231 high-accuracy real-time clock (RTC) module, and a 16×2 I2C LCD display. The ...

The Type K thermocouple is the most common type. It’s inexpensive, accurate and reliable and has a wide temperature range. This article shows how to use an Arduino Uno/Nano microcontroller with an ...

I’ve talked about HD44780 displays before – they’ve been a mainstay of microcontroller projects for literal decades. In the modern hobbyist world, there’s an elephant in the room – the sheer variety ...

The I2C (Inter-Integrated Circuit) bus is a synchronous serial communication protocol that allows multiple electronic components (sensors, displays, memories, etc.) to be connected within the same ...
