design two digit up/down counter
Excuse me Brumi..I have a question. I had decided on using that first schematic you posted. and after researching around, that page displays the counter to be a 4510....but shows it as 16pins... but when I looked up the 4510 datasheet..it is a 14pin IC.
That...
single button down count on up down counter
Would it be hard to hook up to that schematic? Would I need to change the PCB layout?

Ok that was a stupid question. I researched and learned more about it. Now my question would be Where do I put it on the board..and where...
pcb layout for 2 digit up down counter
Alright, I have decided to use that first schematic for my counter. Now I just need to figure out how to use a wheel that spins one way to count up, and spins the other way to count down. Any advice?
4029 up down counter
Cool, for this project I am trying to keep it as cheap as possible. After researching some LCD displays and controllers...I think I ruled it out as being too expensive. I am also trying to keep it fairly small. no bigger thana cigarrette pack.
Is there any small premade...
digital counter schematic
Thank you for the schematic...but does sort of confuse me a bit. Is that for making a circuit board?
well, I think i've decided against the LCD screen. I don't think it will be cost effective.
I would still like to have it change colors...but I dont know if thats...
2digit up down counter
Hey all, let me just start by saying that I am completely new to circuit boards and such. But I am looking to build my first simple device. I want this prototype to be as cost effective as possible and as small as possible. (no bigger than a cigarette pack.
Heres my...
