Hi everyone,
This is my first post on Electro Tech. I am a first-year college student in an engineering program, and I was thinking of making a very simple ping pong scorekeeper for extra credit in a class I am taking. I took a look at some other posts, but they all seemed to be much more sophisticated, with a timer, and period indicator, and time-out indicators.
I would like to make a simple two digit score display (up to 21 points) Also, I would like to have a manual switch on each side of the table. When the switch is depressed, the score will increase, on that side, by one point. Finally I would like to make some kind of reset mechanism. It could be a third button, simply pulling a wire to remove the power, or once one side of the table reaches 21 points (button presses), the 22nd button press will bring the counter to zero.
I plan to use:
(2) two digit, seven segment displays, one per side (small, ~1 inch tall)
(2) simple manual switches, one per side
(1) power supply (9 volt battery perhaps?)
Some kind of a circuit board to connect everything to and provide programming necessary for operation. I don't really know what kind of circuit board will be sufficient for this project. Is this something I could ask someone at Radio Shack?
Any tips or pointers would be GREATLY appreciated, I really enjoy tinkering with little projects, but have only done "all-in-one kit projects" before. I want to step up to the big leagues and build my own little gadgets now that I'm in college.
