IRQ - This is an interrupt pin and the job of this pin is to alert ... Keep in mind that SPI pins are different in different versions of Arduino. In Our board which is Arduino Uno, the SPI pins are 13 ...

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 ...

If you're looking to add wireless communication to your project, the Arduino nRF24L01 module combo is one of the most reliable and cost-effective… ...

Furthermore using floats gave a smaller footprint on the Arduino UNO. Note that the 24 bits of the HX711 contains ... To select this mode connect the RATE pin(15) of the chip to VCC (HIGH). Connecting ...

“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 ...

The version 0.3.0 has breaking changes in the interface. The rationale is that the programming environment of the Arduino ESP32 S3 board uses a remapping by means of the include file io_pin_remap.h.

OK, year-old pop culture references aside [Kyle] dropped us a line to show us his tutorial on using interrupts with your Arduino ... since you are not polling a pin over and over.

It’s a significant update. The Arduino UNO and Arduino Mega 2560 update the Duemilanove and Mega respectively. They now use an ATMega8U2 instead of an FTDI USB to serial converter chip.
