 1 | # Awkbox
 2 | 
 3 | A Raspberry Pi-powered soundboard that plays stupid sound clips when shaken.
 4 | 
 5 | ## Construction
 6 | 
 7 | This uses a Raspberry Pi Zero and a Speaker pHAT.
 8 | 
 9 | * Set up the pHAT: https://learn.pimoroni.com/tutorial/sandyj/assembling-speaker-phat
10 | 
11 | * Add a sensor; this uses a tilt switch but this could easily be replaced with a button switch or similar.
12 | 
13 |   Wires were wrapped around the header pins 5V, Ground and input 23 for the switch.
14 | 
15 | ![Pi](assets/circuit.jpg)
16 | 
17 | ## Code
18 | 
19 | * Install the software by following these instructions: https://github.com/pimoroni/speaker-phat
20 | 
21 | * Check this repo out onto the pi
22 | 
23 | * Set up the script to run on boot by editing the following file:
24 | 
25 |   ```
26 |   sudo nano /etc/rc.local
27 |   ```
28 | 
29 |   Add to the bottom of the file:
30 | 
31 |   ```
32 |   # awkbox
33 |   python /home/pi/awkbox/awkbox.py &
34 |   ```
35 | 
36 | ## Misc
37 | 
38 | Add .mp3 files to the `sfx` directory.
39 | 
40 | To adjust the volume control:
41 | 
42 | ```
43 | $ alsameter
44 | ```
