8 LED multi-mode scanner - multicolour

This 8 LED chaser module uses a PIC microcontroller to produce a number of great chasing modes. There are 11 modes plus a demo mode, which runs through all of the others in sequence.

There's also a speed control trimpot and the modes are selected by pressing a small pushbutton switch. Once a mode is selected, the module remembers it next time it's powered up.

Power supply can range from 8 to 14V DC. PCB dimensions are 74mm x 36.5mm.
