This is my trigger circuit that turns on when it hits 30 degrees, I haven't put all three circuit together yet to make a whole circuit, I would imagine I would need to connect it with the 555 timer to make it switch off after 120 seconds
I said about the re-wiring because I can change the...
Ah, yes so after I connect my trigger circuit to my adjustable delay circuit, will I just need to chance the values of the resisters or have to re-wire to make it turn off after 1 minute?
Hi,
Basically, this 555 timer should be connected to the audio generator so when it is activated, it will turn the alarm off after 1-2 minutes. I didn't mention about the trigger circuit. I have built a trigger circuit also that will activate when it hits 30 degrees (0.3V), do I need to connect...
I am using proteus isis to build my adjustable delay unit with a 555 timer connected to it. The resisters and capacitors have values when changed will delay the current to make it turn off after so long. No matter how many values I changed it will not turn off and continues to light the LED. I...
