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 project is an Arduino-based calculator that uses a 4x4 keypad for input and an I2C LCD for output. The calculator can perform basic arithmetic operations such as addition, subtraction, ...

This is the Sensirion STCC4 library for Arduino allowing you to communicate with a STCC4 sensor over I²C. Click here to learn more about the Sensirion STCC4 sensor. The default I²C address of STCC4 is ...

Arduinoで人気の小型ディスプレイ「OLED」。いざ接続して、よくあるLCDのサンプルコード（LiquidCrystal_I2C.hを使うもの）を書き込んだら、fatal error: LiquidCrystal_I2C.h: No such file or directoryというエラーが出て動かない…。 このエラーメッセージだけを見ると ...

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 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, ...

The ARDUINO IDE associated with the ARDUINO board uses specific numbering, assigning numbers from 0 to 19 to digital pins 0 to 13 and numbers A0 to A5 to analog pins. GCBasic directly manipulates the ...
