ive been searching high and low for a thread similar. a few came up but doesnt rpovide me the info i need. so i think better if i open a new one and make sure it completed. people would recommend using a PIC but i just want to make it simple and cheap. so i choose the 74LS192, but the counter doesnt work as it should. the counter start at 1 when it should be zero and the second 7seg doesnt show any number. im planning to connect the circuit to ta relay to control the light. any recommendation on how to do so? some helps, advice would be very nice.
the circuit below is generated with livewire pro.
i put a switch next to the phototransistor for testing purposes only.
