Hi,
I'm very new to electronics so please bare with me.
I'm after building a timer circuit that will operate from a 12 volt DC
supply, the timer will control a small heater that I have built from 6
x 33 ohm resistors.
This small heater is fixed to a processor that isn't very stable when
it gets cold. Anyway the processor works fine when it is warmed up a
little. The timer will only allow the heater to be on for approx 4 - 5
seconds.
I would however like to add extra control to the circuit with a device
to interrupt the timer when the temperature of the heater reaches
approx 15 degrees C.
Could anyone explain the best way for me to do this.
Thank you.
