ABSTRACTIn this work, we designed and constructed a digital counter circuit. The initial design criteria for the project were: to have a two digit output, to have the circuit count from 0-99, to include either a 555 timer or manual counter. Research was conducted into similar analogue electronic circuits and a suitable point of a digital die was identified. The digital counter circuit was designed using BCD 4506 binary counters and 7-segment display outputs. The circuit was modeled using prot...
