Im writting a code to read from both LDRs and show the reading on LCD and I want to see if it's working
but I dont know how to connect the LDRs with the PIC??
If your chip has them, you will need to use the comparators or an ADC input. Then put a resistor in series with an LDR to form a divider; connect the resistor to the PIC's Vdd and the LDR to ground. The centre tap between these points is proportional to light levels.
