Simple time circuit
Hi, I need a simple switch time circuit possibly using the 555 or 556 chip application as follows
(1) Press a N/O press button to activate a relay and at the same time indicate an LED light
(2) The process should remain activated fo approximately one hour and then switch off
(3) There should be a delay of five seconds before the timer can be activated again
The timings given are not critical, I would like to have pot to time between 1 and 2 hours (not critical)
Would appreciate a circuit diagram and component values, using 12v transformer rectified to DC
Thanks
Ken
