What is pcspkr_keyboard?

A program used to control a PC speaker that is hooked up to a computer (such as the Raspberry Pi) that has GPIO pins using PWM.

YouTube video here.

How do I use it?

First, obtain a PC speaker. Hook it up to pin #18 and GND (ground). Polarity (+ -) does not matter. If you want to reduce the volume, simply add a resistor to the circuit.

Then, download the script and execute it.

./keyboard.sh

Keys available: Q 2 W 3 E R 5 T Y U 8 I 9 O 0 P - [ = ] \

Note: Keys TAB and 1 do not work, because the command in the script 'read' cannot take TAB. 1 doesn't work because I'm too lazy to add it. :P
