Hey guys,
already got lot of informations out of this forums. THANK YOU FOR THAT.
I´m working on little project but can´t best solution.
In general I need a simple 12V low batterie alarm (with a low current, cut voltage by potentiometer, 1/60Hz Alarm Tone).
I created a circuit with a LM358 with a Trimmer Potentiometer and a piezo etc.
Works fine, but I don´t need a continuous alarm and the current was bit hight (10-20mA passive / 60mA active)
Now I thought making a sound each 1 minute (1/60Hz) is simple, but I have read so many solution that I´m not sure anymore what solution is the best.
Stay to the LM358 and add circuit for the interval tone? Is there any out of the box solution?
