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。

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 ...

This data logger uses an Arduino, an ibridge keypad ($8,90) and an Nokia 5110 LCD screen ($6,80;iteadstudio). I am writing a library for the keypad and the graph screen to view the measurements.

Article Arduino as I²C Slave Arduino as I²C Slave The venerable I²C bus has never been more popular. Most modern microcontrollers either have a hardware I²C interface or are capable of bit-banging one ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

[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 ...

Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...

Arduino has just launched a “Plug and Make” kit designed for beginners with an Arduino UNO R4 WiFi board, several “Modulino” modules, a “Modulino” base to neatly attach the UNO R4 and modules, and ...
