AllesonBong WROTE:For the moment I use only 3 LDRs..what do you have in mind? I would like to hear it
Only 3 LDRs ? Should be a piece of cake.
I've just started a similar project that monitors 16x 24V 48W dc lamps used in a boat. I use 0.1 ohm in series with the lamp to drop 0.2V and use that as an input for my PIC. As my PIC only has 8 ADC, I have to use multiplexers to combine 4 inputs to one output and an op-amp to amplify 0.2V to something higher before entering the ADC.
I dont need GUI to display the activities. Just a front panel with LED and push bottons controlled by a second PIC. The 2 PICs would talk to each other using UART interface. Have you started with the LDR and writing programs for PC GUI or the C programs for the PIC? You can always simulate the PIC part on proteus. The Proteus is quite powerful, it has a UART terminal built-in and can be called out to test the PIC UART functions.
