Ronv,
On the Simulator, everything worked well, however on my Bread Board the circuit worked a little different. I was able to achieve my desired time period, but the motor did not turn on for that period of time rather than running at 100% before returning to the adjusted Pulse Width.
I have experimented with this for a while and eventually migrated to a 556 timer. Now I am using the first timer to provide +12V for 2 seconds and then go to 0V. Based on the Simulator I took the output of Timer A and attached it to the Trigger of Timer B, witch appeared to do as I expected. However I soon discovered that on the Bread Board it did not work either.
What I have determined is that when I set the Trigger of Timer B to Negative, after it has first been initialized with power, it will cause Timer B to run the motor at Full capacity.
This is what I want, but I need Timer A to establish a negative connection and then open the circuit so the normal operation will continue. (i.e. A Normally Open, Electronically controlled, SPST, Digital Switch.)
Through Trial and ERROR, if have now made my 556 timer stop working on the motor side, although I am not sure why…
Is there an easy/cheap way to open and close a connection electronically?
Best Regards,
BHinote
P.S. I found that the software I have been using does not have sophisticated Trial Periods. I backdated my machine to a week ago and found that I now have 7 more days to evaluate it.
. I am not sure if this will continue once I let the trial period laps, but is does give me a few more days to finish things up…
