Hi
I am wiring a 555 timer as monostable and I know when the trigger is grounded this strarts the monostable timing. I want to know at what point for the 555 the trigger is counted as being LOW and also what point is it HIGH, if my supply voltage is 9v will this point be half which is 4.5v which is what I would like it to be. The trigger will be coming from ldr/variable resistor potiential divider as seen in diagram.
If not can somone suggest a device trggered by about half supply voltage.
Thank you for any replies
