I need help to start a project, which my grandson (11 years) and I (an old duffer of 75 ) intend for a summer holiday project. We want to create using 7 segment displays a "hymn board" in our local church. It needs to comprise at least 6 banks of three per bank of large 4" high seven-segment displays
A switch per bank will illuminate all "zeros" and then by using a push button switch per numeral, one is able to increment the number from 0 to 9. A simple incremental circuit. Thus Hymn no: 349 on bank 1, no 596 on bank 2 can be displayed. We could build a "bread-board" to experiment and having ironed out any snags, then build a prototype for the vicar's approval
I have some knowledge of electonics, having worked as a pcb draughtsman way back in the 1960's
I hope I have been explicit enough
Thank you very much
