I am developing a game for my kids. it basically works like Skee-Ball where an object goes through a hole and creates a score. I want to have four holes that have sensors to detect the object has come through the hole and what color it was which will tell the computer which of the four holes the object came through and what color it was so it will add the relevant points to that colors score.
So far I have some color sensors and some led rings I am going to use as targets around the holes and to signal the user the sensor has recorded the object passing through the hole.
I have a few different boards nano's and uno 3's I'm just not sure where to start.
Thanks in advance for your suggestions!
