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 ...

The designed mobile robot could navigate, detect and extinguish fire autonomously. Arduino Uno was used as the microcontroller to control the flame sensors' input and output of the flame extinguisher.

The 23 bits mantissa of the IEEE754 float matches the 24 bit ADC very well. Furthermore using floats gave a smaller footprint on the Arduino UNO. Note that the 24 bits of the HX711 contains some noise ...

“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 ...

One can overrule the default seed with fixed values to generate a known sequence as this is useful for testing. Tested on Arduino UNO + ESP32. Feedback as always is welcome. Breaking change in 0.2.0 ...

[David Hansel] shows us this in style, with a floppy interface, software library, and even a rudimentary DOS, for the humble Arduino Uno. The library provides functions to allow low level work ...
