how to measure frequency in this circuit?
i want to measure the frequency of this flasher circuit but i always get a frequency close to that of the mains. I am using a wall wart.
i changed some of the components to speed up the flashing but the frequency reading stayed the same.
to check my multimeter i tried measuring the frequency of mains and the joule thief circuit and it looks like my multimeter is good.
how should i measure the frequency in this flasher circuit?
