The piano keyboard is arranged in an 8x7 matrix, and my program successfully reads the matrix input. In this tutorial, I'll give you the lowdown on how to use the ESP32-S3 chip as the main controller to create the keyboard of your dreams. This is a great project for those who want to control thei # define BUTTON_PIN 21 // The ESP32 pin GPIO21 connected to the button volatile bool buttonPressed = false; // use volatile for variable that is accessed from inside and outside ISR void IRAM_ATTR handleButtonPress(); void Example of HID Keyboard BLE with ESP32. Convert USB Keyboard to Bluetooth LE using the ESP32 S3 We read every piece of feedback, and take your input very seriously. This library will let your ESP32 microcontroller behave as a bluetooth mouse, keyboard, gamepad (XInput or generic), or a combination of any of these devices. This type of keyboard has 2 HID interfaces, so some microcontrollers cannot recognize it correctly, so when touching the touchpad, errors occur. This is a good Bluetooth LE Keyboard library for the ESP32 (Arduino IDE compatible) - T-vK/ESP32-BLE-Keyboard. 3. Pretty nice way to add versatile input to your project and without worry to run out of buttons! Report comment. It is different from traditional controllers as it features a 0. About. And Feather means it works with the large community of Feather Wings for endless possibilities! This project turns an ESP32 S3 into a HID keyboard. Sign in We read every piece of feedback, and take your input very seriously. It is a bit like Makey Makey, that made it possible to connect to laptops (or devices that allow USB); this library can help you to create wireless connections from the ESP32 to anything that supports Bluetooth low energy (BLE). Hi guys, just wanted to share something I've been working on for a while.
