reed switch and uses

[gatoulisss]

hello guys, i want to use a reed switch like an on/off switch but also as selector.
i have connected it in a pull up resistor and to a pic16f88 port.  the use  i want to make for example is 3sec the magnet to the switch then system on if i release and put the magnet again for 3 sec there then it is becoming off, but if i dont release then after 4 sec (3-on+1) then is selecting mode A, 5 sec (3-on+2) then is selecting mode B and 6 sec (3-on+3) then is selecting mode C till i release. in the system program im checking a sensor and is in 4 mode silent (on state) 15sec ring (mode A) 30sec ring (mode B) and last 60 sec ring (mode C)
i have problem in ho to use the on-off and the mode selector code... any help with it?

Can you post the code? Are you using a software debounce for the pulse of the reed?

A Finite State Machine with a timer can solve your problem very efficiently.

By the way, have you consider a hall effect transducer like A1190 in place of the reed?
