First of all I would like to say that I am a complete electronics newbie, I literally know nothing so any advice is going to have to be simple and step by step.
Here's the situation, i'm trying to design a battery powered counter that uses three seven segment displays. I'm using a very basic simulator program called crocodile clips so apologies for the quality. There are only two switches that are really important in my design. In the top left is the on/off switch, and on the right of the second seven segment is the switch that will increase the displayed value by one. However when I turn the circuit off and then on again the decoders and counters break. I believe that i may need some sort of voltage regulator, if so can somebody please show me exactly what i should do, if not any other suggestion would be welcome
