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 ...

The two SCD41 sensors we want to connect have an I2C address of 0x62, which cannot be changed. Therefore, to communicate with both sensors from the micro controller, we will use a separate I2C bus for ...

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 ...

// Scans the I2C bus and prints any found device addresses (in hex) to the Serial console. // Buy this module: https://shillehtek.com/products/pcf8574-i2c-serial ...

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, ...
