Good day,
I actually have two Questions. to begin, the project that I am building is based on Dr. Hulda Clark's zapper. This is a device that generates square wave pulses using a 555 timer. I have a good understanding of the circuitry for this device and my project will be built on a breadboard. I am going to do some improvements to this device that will allow me to have adjustable voltage as well as adjustable frequency. I will be using a potentiometer for those purposes. My first question concerns the voltage. I want to incorporate a string of LED's that will indicate an increase in voltage. So, at low voltage one LED lights up, as I increase the voltage the next LED lights up, until finally at maximum voltage all the LED's are lite. What would be the best way for me to do this with my breadboard. My second question is that I want to do the same thing for changes in the frequency. Low frequency lights up one LED, maximum frequency lights up all of them. Any help you may provide is greatly appreciated.
Source voltage will be AC/DC walwart 15v 400ma(probably).
standard white led
