"Chaser lights with the port expander" handler om en lille kreds MCP 23017, der fungerer som en port expander og kan styres fra en Raspberry Pi. Dvs man styrer med to porte på Pi'en og har så 2 x 8 GPIO porte på MCP 23017 at gøre godt med. Fx til at lave løbelys med. Resten af bogen er på samme måde en hands-on vejledning i at styre hardware med en Raspberry Pi.

Af underlige årsager har man trykt denne her bog på gråt papir. Det gør bogen markant vanskeligere at læse. Heldigvis kan man finde en pdf-udgave på nettet.… (plus d'informations)
