hello people....
as part of my eye movement project, i rigged up a circuit thats working well and gave me the two outputs (images 1 and 2 attched below) when i look right and left... note that when i look straight i got a 0 output...
to differentiate between the two movements, next i wish to convert these results into digital for which i want to use a PIC16f877 uC... however i learnt that the PIC wont accept negative analog inputs...
can u offer suggestions on how i can achieve this A to D Conversion???
