i need an electronic circuit timer diagram Answered

1.It must be electronic
2.it needs to have the ability to set somthing off like an alarm.
3.it must be small
4.it does not need a display
5.it needs seconds and hundreths of seconds
6.it must be programed electronically. like by a computer or somthing smaller.



Make it a functional diagram, then figure out how to do each function in electronics:

0 check for computer communication
0.1 act on computer input
1 check for user input
2 act on user input
3 modify variables based on time lapsed
4 output information to computer/user etc

What have you got so far ? Apart from a homework assignment ?
