#128263 - cheep access-control system Responding to: ???'s previous message |
I am really very sorry fro not replying for long time actually I like to develop some access-control system. With 89c51. I tried SIM card because I found one old SIM for free. But I cannot able to interface it with 89c51. So I request you if any one can suggest any idea for cheep access-control system. Then please let me know. I also tried 24c16 |
