Hello, I want to use 555 timer to generate a variable frequency waveform with a 50% duty cycle. Please tell me if this **broken link removed** makes sense.
Basically, the idea is for capacitor (C1) to charge through Rc+RV and discharge via Rd + RV. Since Rv is a 10K POT, I should be able to vary the frequency by adjusting it without affecting the duty cycle.
Does This make sence ?
Thanks
P.S. I apologies for the size of picture...(damn that scanner)
