Before we make this DIY, we consider some display screens,such as LCD,Touch Shield~~but it seems too small,so we decide to use 7 Segment Display - 8 Inches
and it seems big enough~~ 
and we need a smaller screen to display innings,so we add two 7 Segment Display - 5 Inches
we can use Rainbowduino v2(of course Rainbowduino V3 is more better) to drive them,and it’s more convenient instead of other handmade-driving.
And then , we start to combine them together.
First, we need a blueprint
The two 7 Segment Display - 5 Inches are the same connection
And followig is the others’ connection
So , we have done the section of display , and then we can use RTC to adjust time.Also we need a IR Receive, we can use a telecontroller to control the score indicator.
wow~we have done it almost, but the last thing is telecontroller.
you can make a new telecontroller, or we can use a ready-made.
