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 ...

You can create a release to package software, along with release notes and links to binary files, for other people to use. Learn more about releases in our docs.

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 ...

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 ...

[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 ...

Arduino was created in 2003 by a group of students at the Interaction Design Institute Ivrea (IDII) in Ivrea, Italy, to simplify electronics for non-experts. A group of students, including Massimo ...

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 ...

The Arduino is a powerful platform for interfacing with the real world, but it isn’t without limits. One of those hard limits, even for the Arduino MEGA, is a finite number of pins that the ...
