We come to add LED Flasher for Monitor the electric current of battery 1.5V and 3V. By use the integrated circuit LED Flasher or Oscillator. By the rate something flasher equal to 2V. This circuit eats electric a little current poor age the work of battery long can’t be like be usable. If friends use battery 3V as a result liberate pin 1 float keep. I hope that a friend may apply with Battery 1.5V or 3V Monitor Circuit , please sir.
