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 ...

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 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 ...

Building radio receivers from scratch is still a popular project since it can be done largely with off-the-shelf discrete components and a wire long enough for the bands that the radio will receive.

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 ...

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 sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...
