like suggested above Arduino Nano board. Or use 8 pin ATTINY85 ???Hi,
I probably would use a small microcontroller. (maybe a 8 pin one is sufficient)
on pin to arm the alarm, off pin to disarm alarm e.g. car alarm, on to turn on, off to turn off and alarm will only trigger when armed and off will also turn off when triggered.This is a possible working example, but logically the off input I do not seem to understand. Is the off
pin to terminate an ongoing on alarm after the .5 sec ?
Regards, Dana.
sweeet, i want to give this a go, what exactly do i need to make it happen? like what programmer what hardware etc...This will sound alarm for min 5 sec, after than stay off until alarm off button pushed.

relay and a horn. i guess the output of the chip will goto a 547 transistor to power the relay.What does the alarm signal go to led, piezo.....?
Regards, Dana.
so the ATTiny85 connects to the arduino nano development board for programming, once programmed the ATTiny85 is used by itself, right?
