This project demonstrates communication between an STM32 microcontroller (Blue Pill) and an Arduino board over I2C. The STM32 controls four PWM signals to adjust LED brightness based on data received ...

This project demonstrates the implementation of I2C communication between two Arduino boards to create an automatic barrier system ( GateGuru) . The first Arduino (Master) controls the barrier, while ...

ラズパイやArduinoでセンサーなどを使うときにI2C通信がよく使われています。この場合、ラズパイやArduinoがマスターで、センサーがスレーブになって、マスターからスレーブのデータを書き込んだり、データを読み出したりします。 センサーなどの代わりに ...

The new ASX00073 UNO SPE shield from Arduino is now being shipped by authorized distributor Mouser Electronics.

秋月電子で購入したBOSCH社製9軸センサ「BNO055」を実装したセンサーフュージョンモジュール「AE-BNO055-BO」を使用し、「Arduino UNO R4 MINIMA」とI2C通信を行いました。が、動作確認できるまでに少々苦労したので備忘録としてまとめました。 下記が回路構成です。

SPE is a new Ethernet communication standard that allows power and data to coexist on a single pair of wires, referred to as Power over Data Line (PoDL). This permits faster data transfer and ...

[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 ...

PJON, pronounced like the iridescent sky rats found in every city, is a cool one wire protocol designed by [gioblu]. [gioblu] wasn’t impressed with the complications of I2C. He thought one-wire was ...
