The Wire-free Breadboard - A Feasibility Study on Digital Circuit

Abstract

For over forty years, the breadboard had been a useful tool for basic electronic experiments. However, even for an experienced user, a complicated wiring work could be a nightmare during the process of experiment. Not only it takes time for wiring, but also a non-logical error may arise whenever there is a loose contact between jump wire and the electrical terminals of the breadboard. That is to say, sometimes, you cannot ensure that the confirmed circuit works correctly even after a careful wiring work. In this paper, focused on digital circuits, we have designed and implemented a "wire-free breadboard" prototype. Based on the technology of FPGA, a circuit system, which being located on the bottom side of the breadboard, has been built to substitute the jump wires on the top side of the traditional Breadboard. To save the time of wiring work and to avoid the non-logical errors of electronic experiments are the main motives of this research.
