SCOREBOARDS ARE EXPENSIVE! Not only that, very large 7-segment LEDs are expensive, too! Scoreboards can give your team a sense of legitimacy. After looking at scoreboards all over the internet
, I thought to myself, hey, I don't need to buy a scoreboard, I Could Make That!
My idea was to make a scoreboard for our softball team utilizing an Arduino, an IR remote control and LED strips. I decided to use LED strips to make large 7-segment LEDs because it would cost less than buying large ones. My idea is to make the scoreboard for less than $100.00.
The scoreboard displays the visitor and home team scores to 2 digits, the inning to 9 and the outs to 3. Since our league doesn't count balls and strikes, I ommitted them but they can be added in a similar fashion to how the outs were done.
The segments are controlled with an Arduino Mega thru 74HC595 shift registers and TIP-120 NPN transistors with 220 Ohm resistors. The scoreboard circuit was created using copper tape that was adhered to an IKEA table top. The scoreboard is powered from any car 'cigarette' lighter, a 12V battery or a Booster Battery Jumper module. It can also be powered using a 9V-12V wall wart. Watch the Video.
