A temperature-based dual safety system addresses common household risks through intelligent control. Built on an Arduino Uno, it operates in two selectable modes via a slide switch. In one mode, the ...

The I2CKeyPad library implements the reading of a 4x4 keypad by means of a PCF8574. Smaller keypads, meaning less columns or rows (4x3) can be read with it too. Since 0.3.2 the library allows a 5x3, ...

The I2CKeyPad8x8 library implements the reading of a 8x8 keypad by means of a PCF8575. Smaller keypads, meaning less columns or rows (e.g. 5x4) can be read with it too. Feedback as always is welcome.
