Sorry for late reply.
I can’t understand ‘part number’ sir.
SIM300 GSM Module, IR LED & Photo Diode, 16×2 LCD Screen are being used.
GSM Module & IR modules are connecting to port3 & LCD to Ports2&0.
Thanks again sir.
When an object goes between these IR’s, using distance/time, we can calculate the speed of object interrupt & timer in8051.
Can you give me the pin configuration please?
Thank You sir. Can you represent it with a block diagram/ pin representation please. My project work depends on your reply.
