CAn someone please tell me why the relay would not trip on this circuit?
This is a simulated circuit with a 5volt relay
The output from pin 7 of the lm311 is activated with 8.3 volts to the relay yet it does not change state. Does there have to be a certain amount of current and if so how can i increase it to the relay as changing r2 doesnt make any difference with regards to making the relay trip
thanks
graham
