my project will only be experimented in a room instead of under the sky... i will be using torch light..my project is not as complex as u think
basically, my project is like: start from comparing the LDR(which is my biggest problem at the moment on how to compare them,x1 compare with x2, y1 with y2), then send the signal to PIC16F877A, then to driver L293D to drive the servo motor.
my model will be something like this:
YouTube - Solaruino, just a simple solar tracking project with the arduino duemilanove
anyhow, i really appreciate help of u all... thanks a lot....

betwixt : as u say, we can use software to make the comparison, but we do not know how to make it? what software we need to use? and how we make the compare? we only learn some basic on assembly language and C language in mplab ide, are u using the same software?
can u please teach us? thanks a lot....

i have try the circuit that u send to me, but it not working as the both led also turn on....
i think most properly is the value of the resistor cause this problem, i have using 5 k resistor for the set window and 4.7 k for pull up resistor, is this value correct

kak111: i'm so sorry, the circuit is working, thanks for the help.... we have adjust the value of the resistor.... really thanks a lot... ^^
