ABSTRACT:
The specification discloses a logic learning apparatus including a housing having a plurality of two position switches mounted thereon for movement between logic "0" and logic "1" positions. A plurality of discrete electronic logic circuits are connected in parallel to the switches. Light emitting devices are connected to each of the electronic circuits and are operable to be energized when the switches connected to the circuits are properly operated. A plurality of cards are provided with visual diagrams of different ones of the logic circuits. The housing includes a well portion for receiving the cards, such that the inputs on the cards are positioned adjacent the switches and the outputs on the cards are located adjacent predetermined ones of the light emitting devices. Correct operation of the switches result in illumination of the predetermined light emitting device.
