I want to build a 10-15'' square or round wall panel and hang it on a wall. This I call the target. My son is supposed to hit it with a soccer ball. When he hits it the panel should change its color e.g. to green.
I've seen it already in some amusement parks, it's like a 7x7 wall panel each 10-15'' and you are supposed to hit it with a ball. I do not need this complexity, I just need it one of this wall panels roughly around 10-15''. I'm just saying it because I know it exists. So it needs to withstand rain, and I need to be able to fix it on the wall. It needs to resist some hits of the ball. Preferably to work with batteries.
Can you please help me find whether this is feasible, and especially which type of panel I need to buy.
Many thanks for your advise! P.S. I searched on google quite a lot, but couldn't find the right keywords.
