Hello,
I need to build a 7 segment led counter that counts up from 0 to 5 and back down. One lever switch (spst or spdt) to count up to 5, and one lever switch (spst or spdt) to count down to zero.
I think this circuit is close to what I need but maybe with a 4029 instead of a 4026.

I need to figure out how to set the up and down status while high with just a spdt switch.
Thanks in advance.
