[solved]Auto door lock system with AT89c2051

here is the screens hot below after i first click the IC then after i left click it disappears.

i tried to change time ang am/pm but no luck.. now i;ll try to restart my PC

ur clicking on all over the diagram just click on ic that ic should get red not a keypad
in the pic it seems that keypad is also red

no i just click only the IC but the keypad also becomes red it seems that it flows from the wire.. lol


in the schematic theres no VCC on 8051. is that okay? will the compiler understand that if didnt put a vcc?

yes that is not a issue ok dear wait some time i eat launch
