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 ...

Displaying data on an LCD is one of the most common tasks in Arduino projects. Traditionally, we connected LCDs using many wires, but with I2C LCD modules, the same task becomes simpler, cleaner, and ...

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 ...

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 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 ...

This project implements a password-based access control system using Arduino and an I2C LCD display. It provides secure authentication with a lockout mechanism after multiple failed attempts. The ...

Experimented with Arduino + I2C LCD display today. I connected an Arduino UNO with a 16×2 LCD using the I2C module and wrote a simple program to display text on the screen. Seeing my name appear on ...

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, ...
