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。

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, ...

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 most difference to the original LiquidCrystal library from Arduino is that this library supports printf() functionality. When using PlatformIO and AVR, to support float you must add following line ...

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 ...

The I2C (Inter-Integrated Circuit) bus is a synchronous serial communication protocol that allows multiple electronic components (sensors, displays, memories, etc.) to be connected within the same ...

This project demonstrates a servo motor angle control system using an Arduino-compatible board. The system continuously sweeps the servo motor between 0 and 180 degrees. A 16x2 I2C LCD is used to ...

Sometimes there’s just no substitute for the right diagnostic tool. [Ankit] was trying to port some I2C code from an Arduino platform to an ARM chip. When the latter code wasn’t working, he got clever ...
