Actually, the first 555 does produce very narrow lows in the simulation using Multisim. Thats really weird if it was really designed that way. Is it a good design?
I tried powering up the first 555 in an actual circuit without connecting its output to the second one. But i got confused because it only outputs HIGH on the oscilloscope and thats why i posted here. The pulses are probably too narrow.
Right after I posted this question, i tried hooking up the output to the second 555 and it now seems to be working fine because the pulse width changes when i turn the pot. But it seems that the ON time is too short compared to the OFF time, guess ill have to check.
