I think I’ve just destroyed 2 servo triggers in the last couple of hours. They were kind of working, but as I tried to solder to them to hook them up to a signal, both seem to basically be stuck constantly in the B position.
I was just trying to do what was in this video - https://www.youtube.com/watch?v=lcSA3hWZ2zg and figured it would take an hour or so, but now I’m a few hours in and it looks hopeless, unless I spend another $30 on more servo triggers that I might destroy if I just keep trying the same stuff I’m trying.
That video shows the guy with a sound detector and servo trigger connected, but the one close up where you might be able to see how everything is connected, his damn hand is in the way.
I’m lost
Thanks for reaching out to us on this.
It can definitely be done in an hour if you are already knowledgeable …however there can be many moments of frustration attempting new things.
It might be helpful to take a picture/video of your set-up to show what you have…the solder points and/or wiring arrangement are the most likely culprit(s).
Instead of jumping in and soldering right away, which can be risky, we always recommend reading along with our hookup guides on the product pages https://learn.sparkfun.com/tutorials/se … 1615791300 to assist in fundamentally understanding the product, and then heading out to modify them to suit your project.
Hope this helps, and happy sparking!
I’d really just like a clear picture of the circuit that’s in the video. I just can’t see how the wires go between the sound detector and the servo trigger.
In the video, it also looks like the breadboard has a voltage regulator or something.
I’m getting this kind of advice on reddit. is this where I should be going?
"So when you get a high output you want a low signal on the input. When you have a low output you want a high on the input. You need an inverter circuit of some sort. The simplest way to do this is a transistor and a resistor. "
Here’s a diagram I was able to dig up.
oh, this is awesome. thanks a lot, now it should be no problem. yeah, 2 power sources, I was wondering about that. thanks again.
For some reason it oscillates when you use one power supply but not with two. There’s probably a way to solve that issue with some filtering, we never got around to figuring it out though.
