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 ...

A web-based tool for creating custom characters for 16x2 LCD displays used with Arduino projects. This tool provides a visual interface where you can design custom characters on a 5x8 pixel grid and ...

This project uses a PIR (Passive Infrared) sensor to detect motion and displays the status on an I2C Liquid Crystal Display (LCD). When motion is detected, a message is shown on the LCD and printed to ...

An RFID-based attendance system transforms the tedious task of manual attendance tracking into an automated, error-free process. What makes this project particularly exciting is how a few inexpensive ...

A lot of great ICs use I2C to communicate, but debugging a non-working I2C setup can be opaque, especially if you’re just getting started with the protocol/bus. An I2C bus scanner can be a helpful ...

Arduino is a digital platform made of open-source components that’s been helping and inspiring engineers, designers, and artists across the globe since 2005. As a platform, Arduino not only has boards ...
