Microcontroller based Photoplotter

Microcontroller Project - Photoplotter
A photoplotter is a printing device that exposes light to a photo sensitive film to produce output. The film is then developed like traditional photos to get the result. There are 2 types of photoplotter, vector type and raster type. Vector plotters move the exposure light anywhere in 2D space to create the image. Need a line from point A to B? No problem, just move from A to B. These are similar to old style pen plotters. Raster plotters, are more like a dot matrix printer, sending out one line of dots, then moving to the next to create an image.
