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 ...

今回は Arduino UNOでステッピングモータを動かしつつ、割り込みで止める 、さらに、LCD（1602）で状態表示もできるシステムをつくりましたので、備忘録として残します。 スイッチを押すと ステッピングモータが1回転します。 回転中にもう一つのスイッチを ...

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 ...

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 ...

An LCD can be made to connect to a microcontroller using two wires with the aid of the I2C interface which includes pins for an SPI interface version for flexibility. The I2C LCD interface is used ...

This project measures the input voltage using an Arduino Uno and displays it on a 16x2 I2C LCD screen. It uses a simple voltage divider circuit to safely read voltages up to 12V. The Arduino reads an ...

A web-based tool for creating custom characters for 16x2 LCD displays used with Arduino projects. This tool provides a visual interface where you can design custom characters on a 5x8 pixel grid and ...

Computer engineer Thiery Guennou based in France has created a new Arduino compatible precision frequency counter 5 or 120 MHz. The inspiration behind the Arduino board was to build an open, very ...
