Line Sensor
Today we were trying to get the line sensor work, and it didn't look like it's working.
The line sensor shows these:
Green
Yellow
Yellow and Red
We said Green is detecting black, and for others we said it's not.
What we were supposed to get was to know if the line sensor works on the carpet. So we tried on the carpet, and it shows Green, Yellow, and Yellow and Red when we were trying on the same carpet.
We gave up, and I didn't get why it was like that.
Why was it like that?
Thanks
