AN INTERACTIVE EDUCATIONAL TOY DESIGNED TO PROVIDE LEARNING ACTIVITIES TO YOUNG CHILDREN AGED 2 YEARS AND OVER. WHEN A CHILD ACTIVATES AN INPUT DEVICE, A MICROCONTROLLER (130) RUNS A PROGRAMME WHICH PRODUCES SOUNDS AND PROJECTS COLOUR IMAGES. LEARNING CARDS (150), COMPRISING TRANSPARENT SLIDES WITH COLOURED IMAGES PRINTED THEREON AND HOUSED IN FRAMES, AND PLACED OVER A LIGHTING SYSTEM (140). THE LEARNING CARDS (150) HAVE AN ELECTRICAL INTERFACE CONNECTING THEM TO THE MICROCONTROLLER (130). WHEN AN INPUT IS ACTIVATED, THE LIGHTING SYSTEM (140) TURNS ON TO PROJECT THE IMAGE ON THE SLIDE; AND THE PROGRAMMES WHICH ARE STORED IN A MEMORY UNIT (120) ARE RETRIEVED BY THE MICROCONTROLLER (130). THE MICROCONTROLLER (130) THEN SENDS THE AUDIO DATA TO A SOUND SYSTEM (170), WHICH OUTPUTS SOUNDS ACCORDING TO THE PROGRAMME. THE TOY MAY ALSO FUNCTION AS A NIGHT LAMP (230), CAPABLE OF PROJECTING MOVING COLOURED IMAGES ONTO THE CEILING.
