Hi, i'm using the voltage controlled oscillator of the 4046, i had it working fine the other day, but now i find that the output is stuck on a fixed frequency, determined by the value of the capacitor C1.
I've attached a picture of how i have it connected, when i change the input voltage, no change in output frequency occurs.![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
(i'm using resistor and capacitor values between 10k and 1M and above 50pf like the datasheet advises too.)
