KeyMatrix is poll event Arduino library for matrix keypads.
With this library, you can easily use your custom-designed keypads in your project. With T9 keyboard support, you will be able to write text on numeric keypads. You can use it as you wish in your Arduino projects. We can also contribute to the project and make it more advanced.
Arduino keypad library intended to provide support to manage keypads, keyboards and button sets for arduino devices, simple but powerful and efficient.
RIFD-Based Automatic Billing system
Arduino Library to facilitate I2C communication between Arduino and Renesas GreenPAK devices. These devices were originally created by Silego, Then Silego was acquired by Dialog Semiconductor, and eventually Dialog was acquired by Renesas.
