# Keyboard Noise Maker
|

|
|
|

|
Ever wanted a clicky keyboard but only had a boring quiet one? The solution is here! This is a dedicated hardware "clicker" that you can associate with any USB keyboard. A daemon running on the host computer listens to events from the keyboard and forwards them to an MCU that does the needed clicking.
|

|

|
|
## Hardware
|
||
|
|
- Arduino
|
||
|
|
- Relay module
|
||
|
|
- Bell(?)
|
||
|
|
|
||
|
|
## Software
|
||
|
|
- USB HID listener attached to a single USB keyboard (tested on Linux)
|
||
|
|
- output of the listener redirected to Arduino's serial port
|
||
|
|
|
||
|
|
## Running
|
||
|
|
|
||
|
|
Flash the Arduino code, build the host daemon, run it and redirect it to the Arduino's serial:
|
||
|
|
|
||
|
|
```
|
||
|
|
cd hid_listen
|
||
|
|
make
|
||
|
|
sudo ./hid_listen > /dev/ttyUSB0
|
||
|
|
```
|
||
|
|
|
||
|
|
## TODO
|
||
|
|
- USB device IDs are hard-coded, should be taken as CLI parameters
|
||
