Two ready-to-upload Arduino sketches for finding the addresses of I2C devices on your bus. Stop guessing addresses and stop digging through datasheets — scan the bus directly and get the answer in ...

🔍 Universal port and I2C device scanner for Arduino, ESP32, and ESP8266 microcontrollers. Automatically detects active ports, connected sensors, and I2C devices with automatic identification. Arduino ...

A lot of great ICs use I2C to communicate, but debugging a non-working I2C setup can be opaque, especially if you’re just getting started with the protocol/bus. An I2C bus scanner can be a helpful ...

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 ...

ラズパイからArduinoにファイルを送りたい場合があるかと思います。例えば、音楽ファイルとか画像ファイルとか。 あらかじめSDカードに書き込んでオフラインで渡すというので用が足りる場合は良いのですが、動作中にデータを変えたい場合もあるかと思い ...

If you’ve ever been laying out a network I2C devices inside a project box or throughout your robot’s body, you’ll probably know that I2C is not without its pitfalls. But for many of those pitfalls, ...

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 ...

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, ...
