With just an Arduino UNO R4 and a few lines of code, you can make that happen—no expensive GSM module required. To make Arduino send a text message to your phone without using a GSM module, you don’t ...

One of the more interesting applications of this circuit would be to replace or to realize a smart sensor with Arduino. The 4…20 mA standard was introduced a few decades ago, to replace the existing 3 ...

A low-power, compact keypad module based on the STM32L010K4T6 microcontroller. This project includes a 12-button keypad interfaced with a host MCU via I2C or UART, designed to serve as a mini keyboard ...

“Uno R4 WiFi includes an error-catching mechanism that detects run-time crashes and provides detailed explanations and hints about the code line causing the crash,” according to Arduino – Electronics ...

This library enables an Arduino or other compatible hardware to write or read data to or from ThingSpeak, an open data platform for the Internet of Things with MATLAB analytics and visualization.

[Andrea] just sent us this great student hack he made for his room. He’s constructed an Arduino keypad door lock — without using any proper fastening hardware! The entire build is made out of ...
