the "off time" would be used to sample the ambient light in order to create a base line
would the phototransistor respond if i modulated the emitter at a certain frequency ?
you can look for the rising edge rather than a specific level

I found a green led with photoresistor is much easier, cause I can see what the robot sees
Was there any particular reason you chose green, or was it just the visibility in setup?
after getting the value without the ambient , can i use it for the thersholding method ?
