Many people prototype in Arudino and breadboards, and they connect the two using jumper wires. But the jumper wires are usually excessive and messy. So we invented an Arduino shield that maps Arduino pins to breadboard to eliminate the jumper wire mess. For example, it takes 11 jumper wires to connect Arduino with an HD44780 LCD (in 4-bit data). With BreadShield, just one. Enjoy having all Arduino pins on your breadboard instantly, or swapping with a different breadboard swiftly. And more: you can use other shields along side the breadboard, unlike the cases before where the jumper wires take the precious sockets for shields.
