How can I use hardware keyboard on android using Arduino?

Using Arduino Project Guidance
1

Hello,

I have an old Blackberry, and I want to use it's keyboard as an external keyboard for my Pixel 7 android. I want to disassemble the blackberry, connect it's keyboard to Arduino uno, and then connect the Arduino to my phone using USB-C.

I request anyone to please guide me in the correct direction, as I can't find much information online.

  • I don't know how to connect the blackberry keyboard to Arduino, and how to convert inputs from the keyboard to output on my android phone.
  • What components do I need to purchase? I have Arduino Uno, USB-C breakout board, protoboard and some cables.

Sample project: GitHub - ZitaoTech/BBQ10-USB_BLE_Keyboard: An ultra portable Keyboard Mouse Combo using the original Blackberry Q10 keyboard and the trackpad from BB9900
The above uses a proper processor and firmware, and I want to make a similar project using Arduino.

Any help is appreciated. Thanks!

The rational path is to get the exact project done that you linked to and then port a second keyboard to your Arduino using that example as the guide.

I found this: Interfacing Blackberry Q10 Keypad to Arduino and the OLED Typewriter

Seems like a way to connect the keyboard to Arduino. Looks like I can use this - so I need to get this custom PCB? And then what?

Thank you, however that exact project is no longer available to purchase.

IF there is a bill of material, purchase the individual components and get busy. If no BOM, see if the author will supply one.
