Hi all,
I'm trying to create a frequency with the 555 at about 20-30kHz, but when I try at high frequencies, i just get a constant high output
I'm following this schematic
with a 10nF cap, a 1K resistor for R1, and a 2K resistor for R2, which should be 28kHz; any ideas what I'm doing wrong? can the 555 not handle these high frequencies? because it was working with a 10K pot for R1 and R2 with a 10nF making about a 4kHz arc, I can't think why it wouldn't be working
(yes, I have a decoupling cap on pin 8)
