LED Light Sensor - Need Help Please

[ivanrosales]

To use an LED as light sensor you can use PBP's RCTIME or if you want to use the analog approach try connecting the anode to the input pin and the cathode directly to vss, the following code gives me 0 at dark and ~450 in the light:

Inicio:
suma=0
for cont=1 to 10
adcin 3,dato
suma=suma+dato
pause 100
next cont
suma=suma/10
serout transmitir,0,[#suma,10]
goto inicio

(I'm using 5mm Ultra bright Blue LED)

Regards.
