How to make a wireless keyboard and mouse using the RF module?
It’s possible to make a wireless keyboard or mouse using an RF module. For that, you need a mouse or a keyboard, two RF Transceiver modules and an attiny85 Module. You have to use the attiny85 as the USB host device on your PC else the USB host device on the PC won’t be recognised by the operating system and you have to write your own device driver for the USB device. On the other hand, the operating system identifies the attiny85 as an HID device. So it’s easy for you to configure the USB device as a mouse or a keyboard. You may use the below Arduino RF driver for RF transceiver communication.
