Hello All,
I am working on making my own custom three-channel function generator with duty cycle adjust. I bought three of these electronics kit function generators (http://www.electronickits.com/kit/complete/meas/fg500k.htm) [Broken].
I want to build a project box with three 555 timers wired up as PWMs to vary the duty cycle of the output from the function generators. I looked around online for some simple circuits to wire the 555 timers and found lots of setups. All I know is that it needs to be in one-shot mode so that it only pulses once for every incoming square wave from the function generator. Also, I want to have the widest possible range for the pulse width as possible. The target range I'm shooting for is between 1 ms and the lowest pulse width that the 555 can handle. Could someone point me to a good reference circuit to use?
Thanks,
Jason O
