Step-by-step guide on designing and programming a custom I2C slave sensor device using Arduino. Who Won and Lost in Trump’s Tax Bill Scientists tracking ‘interstellar’ object that has come to us from ...

Abstract: Identification of corrosion in the tool industry is very important because it minimizes the impacts and losses due to damage to the tools used. Although there is already a corrosion ...

This is a board that connects the RC522 board with an Arduino Nano. This project was made out of frustration due to wiring the RC522 board with an Arduino Nano every time I wanted to use it. The RC522 ...

Arduino has just launched a “Plug and Make” kit designed for beginners with an Arduino UNO R4 WiFi board, several “Modulino” modules, a “Modulino” base to neatly attach the UNO R4 and modules, and ...

Arduino libraries, like libraries for other programming languages, help easily extend the range of functions available to users in the standard integrated development environment (IDE). They are ...

The popular I 2 C communication standard manages to perform flexible serial I/O with just a super simple two pin bus: SCL and SDA. It accomplishes this trick with bidirectional timing and data flow.

Today, We will review the Cytron Maker Uno RP2040 development board combining the Arduino UNO form factor with the Raspberry Pi RP2040 microcontroller that makes it programmable with the Arduino IDE ...

The Arduino open-source platform is an excellent way to create your own home and hobby electronics projects from scratch. The logic boards sold under the Arduino brand are receptive to all kinds of ...

The fundamentals of the Inter-Integrated Circuit (I2C) interface, and its associated protocol. What made this simple, robust, chip-to-chip interface so useful for embedded system applications? How the ...
