| That still does not tell me the difference between how they are diven. For instance, can you use the 4 motor ports to drive a servo motor? If not why? Any help appreciated. Chris Rhodes (...) (26 years ago, 5-Jun-98, to lugnet.robotics.handyboard)

| I've had pretty good luck getting up to around 2" by using a standard IR LED and standard IR phototransistor, modulating the IR LED in software, and looking at the analog value returned from the phototransistor like so: { int refl; led_on(); refl += (...)

| 1/2" is actually pretty good range for a basic reflectance sensor. try using them in the analog inputs -- you should get readings that let you read out to about 1". to get better than that, you need a modulated signal, like Pandit has described.
