The Problem:
Whenever I was prototyping on a breadboard I was annoyed by all the wires to setup before the actual project could begin. Arduino projects were much easier. The 6 pin ISP (In System Programming) header alone was troublesome. Make an adaptor to plug a 3×2 pin header on a breadboard. Then cut short wires and connect the controller to the header. Which pins are what? MOSI, MISO and SCK? So I decided to do it only once more.
The Solution:
These little breadboard headers are very handy. They occupy only one more row on each side as a controller would need.
