⭐ Define the symbols on the buttons of the dynamic keypad options - letter and number. Step 3: Programming the Arduino Pro Micro Huge thanks to PCBWay for sponsoring this project. Then, I utilized the 4x4 matrix keypad design to send keyboard keys, supporting up to 32 keys with two dynamic keypad options.įinally, I used two joysticks as a fully-functional mouse, also controlling the dynamic keypad options and modifier keys.Īfter completing my design on a breadboard and testing the code, I designed a controller-shaped PCB (Arduino-Based Mouse and Keyboard Controller) with an integrated 4x4 matrix keypad and two embedded joysticks, displaying Pikachu as its center logo :) The ATmega32U4 comes equipped with a full-speed USB transceiver, which can emulate any USB device. Also, I could utilize such a device to test keyboard and mouse functionalities of new single-board computers, for instance, Raspberry Pi, without kvetching about my lack of a proper keyboard and mouse :) Thus, I decided to create this project.įirst of all, to be able to send keyboard and mouse commands via USB, I used an Arduino Pro Micro centered around an ATmega32U4 - an 8-bit AVR very similar to the ATmega328. For a long time, I needed a simple device allowing me to send varying mouse and keyboard commands to test some of my web applications and games on browsers. To do so, you will need to call this function: Keyboard.begin() As stated in the documentation, there are a few simple functions to control the keys: Keyboard.end() // stopping the emulation Keyboard.press() // simulate pressing a key Keyboard.release() // release a key that has been pressed Keyboard.write() // writes the string of text passed.
