Abstract

The electronic circuit of the luminous display controls the illumination and extinction of several lamps or gps. of lamps according to sequences programmed by the user. The circuit includes a memory which is associated with an address counter whose counting rate is adjustable. A switch is inserted between the memory and address country. The switch divides the memory into several various lengths zones, each position of the switch defines the selected zone. The switch or switches are controlled manually and operate the address counter in a step by step fashion and write into the memory, at each step, a word of logic states. Each bit of the word represents the state, illuminated or extinguished, which one of the gps. of lamps is to take.
