Hi, yes that light on the sensor is a "on" light but when something passes in front of the sensor then the light gets brighter. Also for now that's the only LED I have
...I will be ordering 1 digit LED because I only need 0 to 9 score. Here is the info on that sensor. Thanks!!
Edit: Yes all the digits are showing the same number for now.
Edit2: Actually that light is the signal light on pin 12. If there is not signal then the light goes off. But when the wire it connected the signal comes on and when I put my hand in the front of the sensor the light goes brighter.
