So I'm playing with a 555 chip, you know making an LED flash, working toward a KITT/Cylon sequenceing LED array for, er, um, my son. Yeah, that's it! My son. Anyway, I set up the first part of this circuit http://www.evilmadscientist.com/article.php/CylonOLantern and after getting the 555 portion set up I followed the suggestion to put an LED on it to verify that the circuit was working. I started wondering how to vary the flash rate and duration. Am I understanding it correctly that you can adjust the flash rate and duration with R1 and R2 respectively? With R1 setting the time "High" or "on" and R2 setting the time "low" or off? If that is so, what does the cap control?
Thanks for indulging me,
