Hello
I have a problem regarding op amps. I need to do a circuit capable of generating train of pulses. I thought that op amp sq wave circuit will be suitable, but it generates positive and negative, but I need positive only.
Another problem that I do not know how to get +ve and -ve voltage to the op amp, I know +ve and zero from a battery, or the +ve and -ve from Pw supply, but what if I want to operate a circuit that needs +ve and-ve and I do want to use a battery?
