I have used Maestro before but I think its overkill for my application so if anything else works I would be happy.
I have a 5v DC trigger that I cannot change its duration is very fast but can be picked up by a relay.
I need to output the signal for longer ie if input is 0.01seconds, I need the output to be 0.5 seconds.
I will also need to trigger a servo relay after this but I can do that in multiple ways.
Any suggestions on what to try?
It seems like any programmable microcontroller that can read your trigger signal should be fine, so I would suggest an Arduino or one of our Arduino compatible A-Stars.
If you want to avoid a microcontroller altogether, you might be able to come up with a circuit that does what you want, for example using a 555 timer; searching for something like pulse extender circuit or pulse stretcher circuit should give you some results.
RE the 555 timer (assuming you’re considering it), you should also search for “monostable”, i.e. a circuit sits at low until it sees a trigger, then temporarily stays high for some amount of time.
The Maestro is working perfectly, but I am selling this as a kit so think if I could do it cheaper then that’s a win for everyone.
I’m mechanical so electronics are a little alien to me, but I will look into the ideas.
