Hello, my name is Matt, I am new to this forum. Anyways I have been looking around for a bit on more information on a good way to build a chess timer but haven't found much. So I thought I would see if anyone could give me some advice, or if anyone actually does know where to get some schematics.
Basically what I want this device to do is have 2 displays, 1 for each player. Each display has 2 digits wide for the minuets, 2 digits wide for the seconds, and if possible 1 or 2 digits for mileseconds.
There would be 2 push buttons for each side, 1 of the push buttons is used to cycle through how many minuets you want to start with (for example set it to 5, 10, or 20 minuets) Then the other switch is actually the switch you use to signify your move. Last there is 1 switch in the center of the decive which starts and resets the game.
So for example each player can set the amount of time they need, push the start button and then its ready to go. So player 2 for exampe would hit his button which would start decreasing time on player 1, player 1 makes his move, presses his button, and now his clock stops and player 2's clock starts decreasing time, etc. until one person runs out of time it would be cool for a LED to light up or something. Or also if the main button is pressed then it stops/resets the clocks.
This was just the idea I had, it could deffinetly be dumbed down if anyone had any ideas. I was originally going to use a basic stamp II for this project as this is extremely easy to accomplish using that device, though I would like to be able to make this with using electrical components, for example on a prototype board or something. Also I don't know if its the best solution to use a bunch of 7 segment decoders or what. If I was going to use the basic stamp for example I would use a serial LCD display.
But yeah would like to hear any ideas or advice that you guys have, thanks!
