Abstract
An electronic educational teaching apparatus is disclosed herein for use in learning key subjects such as geography, which has an information card presenting visual question and answer data and supported in a holder or stand which houses an electronic circuit for comparing user input answer data with memory stored correct answer data. In one form, the apparatus includes a microprocessor employed with an input keyboard for entering answer data and an output display to indicate answer results. Internal circuits compare the user input answer data with the stored correct answer data and with interconnecting circuits to sense right and wrong answers with alarm, display and score registering capability. The keyboard input is processed by the microprocessor, then coupled to LED displays via LED drivers. An audible device is connected to the microprocessor for providing audible indications of answer correctness. Power supply circuits, including D.C. regulation circuits, reset and timing circuits are operably interconnected with the microprocessor.
