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. Sometimes you need to control ...

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 ...

This project demonstrates using the LIS302SDL accelerometer with an STM32 microcontroller to read X, Y, and Z acceleration data, display it on an I2C LCD, and control LEDs based on tilt direction. The ...

Building a DIY Arduino game controller requires specific hardware components. The table below lists all the components required to build the Arduino Uno game controller project. These components are ...
