What I'm trying to accomplish is have (2) 4026B counters connected to (2) 7-seg. displays to show 0-99 values. I setup a test circuit and have it working with the carry out to increment the 10's value, using a push button and 555. With each segment controlled by a single 4026B using carry out. Now I am trying to add a new button/555 so I can increment the 10's with the new button/555 and also have the carry out increment when the 1's reset to zero. Is this possible?
Schematic I'm following is located here. I thought I could add a new button/555 and connect the pin 3 of this 555 to the clock on the 4026B...so that two wires are connected to the clock on the 10s digit, the carry out from the 1's and this button.
Bonus question, when I have the single button/555 "0-99" setup working, when I plug in the power it defaults to "10" value and not "00" value, any insight here? May have something to do with alligator clips I'm using on the power leads to the breadboard? Sometimes I can get it to "00" when connecting.
