Rotary Switch to Variable Timing Circuit?
I need some EE help with a project I am trying.
What I need is a timing chip whose time(s) are set by rotating a dial.
Set the dial to 1sec. When you power the circuit (switch) you get a 1sec pulse of power to the output and then it stops.
Im looking to have a 10-12 position rotary dial connected to a timing chip. How the hell do I go about even starting this project? How does one get EXACT timed pulses from the chip...do I need to program it?
I need non-crazy times like 1s, 1/100th, 1/1000th etc.
So, to reiterate my ranting unintelligible self:
set dial to a certain time
power on the circuit
timing chip reads setting on dial and outputs appropriate amount of time in a power pulse
This will allow me to turn on/off a device with perfect timing I can set.
HELP!? Are there things already set up like this? Do I need to get a programmable chip and dev board?
