hi ya'all...
i want to make a simple alternating buzzer\beeper (the sound have to be alternating and not creapy straight buzzer sound) that will sit in my car and will remind me when i forget to turn off my lights. the buzzer needs to be the simplest. it dont have to be loud at all, just noticable.
the input voltage prefered for the circuit is 12-14v.
i've got a lot of 555's that i think can be usefull...
any suggestions will great...tnx
