+## Firmware <a name="firmware"></a>
+
+This project contains Arduino formware for controlling: 
+
+* projector
+* camera (see [intval2](https://github.com/sixteenmillimeter/intval2.git) for more info)
+* light
+* projector + camera

+
+Using a simple interface, this modular platform can be used to control custom-built and modified legacy optical printers. 
 
 
 ## Hardware <a name="hardware"></a>
 
+All hardware for this project is available as plaintext OpenSCAD files and 3D print-able .STL files. The hardware component of this project is aimed at modifying broken Bell & Howell projectors into USB serial-controlled projectors to be used in optical printing.
