Makers, hobbyists and developers that enjoy building projects using the Arduino platform might be interested in a new Arduino micro-controller expansion board called the Spectrum I2C. The Spectrum I2C ...

In case you missed it, the big news is that a minimal Arduino core is up and working on the ESP32. There’s still lots left to do, but the core functionality — GPIO, UART, SPI, I2C, and WiFi — are all ...

This library is written to use the NXP PCF85263 RTC. The functionality implemented is just basic date time retrieval. The device can run in a stop-watch mode. The range goes up to 999 999 hours, which ...

Adafruit has this week announced the arrival of the new Arduino compatible TCA9548A I2C Multiplexer to their online shop, which is now available to purchase priced at $6.95. The latest breakout board ...

The two SCD41 sensors we want to connect have an I2C address of 0x62, which cannot be changed. Therefore, to communicate with both sensors from the micro controller, we will use a separate I2C bus for ...

[Johngineer] found himself in need of an I2C sniffer, but didn’t have one available. Necessity is the mother of invention, so he put together this I2C sniffer sketch for Arduino. The arduino will ...

For several microcontroller projects, the integration of a minuscule display panel can be handy to show relevant information. For example, information gathered by an external sensor module. Here we ...
