A DIP40 chip, specifically, my PIC18F452 microcontroller, takes up too much space on a single breadboard. Here is the solution for such a situation.
The benefit of this is that you can store related components right with your breadboard. The downside is that a double-sized breadboard won’t fit with the fixed horizontal dividers.
Possible extensions to this project include power protection. A zener diode across the power terminals or a tantalum capacitor in series with the power could provide cheap protection against inverted polarity.
