Draw a circuit diagram of a 555 edge-triggered monostable, using a 1μF timing capacitor.
The output pulse length should be approximately 3.3 seconds.
Include a potentiometer across the supply to allow the output pulse-width to be varied by changing the threshold.
Indicate component values and 555 pin numbers (other than the supply pins).
If the potentiometer is set to deliver a voltage equal to one third of the supply voltage, estimate the output pulse-length T.
I am not sure how to calculate the output pulse-length T. I know that since the potentiometer delivers a voltage = 1/3 of the supply voltage then the new upper threshold is Vsupply/3 and the lower trigger level = (Vsupply/3) / 2 = Vsupply/6. But then what would you do?
