Hi fll-freak, I made my circuit as follow-
1- Drive IR LED as normal LED -- Long side of LED pin to Arduino's pin No 13 and short side to Ground.
2- Long side of IR transistor(as you describe) to Ground and short side to Arduino's pin No A0 and 10K resister pass through short side of IR transistor with Arduino's A0 to 5V. That all.
By the way, I got IR light range up to 1 and half feet as I describe above :dance: . I got that info from "https://sites.google.com/site/therobotr ... on-circuit
". I think, the way of connecting IR transistor to Arduino was wrong (positive and negative because it is not like normal LED as describe in the above link) :doh:
By the way, is any way to increase the light range to more than 1 and half feet(as I got).
