High Speed Photography Project - Part 3

Software

The software script is listed below. At the moment it is very basic and requires ongoing work. The next stage is to add a menu option that will enable the user to select the 'sound' or 'light' option. At the moment if both elements of the code co-exist in the sketch it can cause some issues.

The sketch below has both elements contained within, however the you need to comment out either section. I would suggest saving two scripts, one for sound and one for light, it is easy to upload whichever you are using.

The display driver and button code is open source and provided by: www.Adafruit.com
