Hey there, Sparkfun community,
I’m having an issue with a Sparkfun Servo Trigger circuit, which I haven’t been able to solve.
Here’s what the circuit SHOULD do: When pressing an RF remote, each button triggers each servo to turn, releasing a balloon.
What happens: the servo jitters in place, and after about 5-10 seconds, finally opens temporarily.
I have three sub micro servos, three Sparkfun servo triggers, and an adafruit RF receiver running through the circuit, connected to a step down regulator (5v 9A) and off to a battery. I have replaced all the servos, tried different regulators (I started with 5v 2A) thinking it may not be getting necessary current, and just about everything else, but I have no clue why the servos aren’t responding.
Should I be running a LiPo battery to the regulator, or are my current AA’s enough?
Thanks, everyone!

Hi TikiPete,
Sorry to hear you’re having trouble with your Servo Trigger. I have a few quick questions that will help us start troubleshooting this issue. First, do you have the [standard or [continuous rotation version of the Servo Trigger? There should be a marking in the box on the back indicating which version you have. Next, have you tried removing some of the extra components and just running servo(s) by jumping the IN pin to GND with a wire or something? Does that result in any better behavior? That might help point to where the issue is originating from. Similarly, does adjusting the position and timing trimpots help at all? Finally, in case there is something hardware-related that is causing the issue, can you please take a few photos of your boards and circuit and attach them to your reply? Please do your best to make sure they are clear and well-lit.](SparkFun Servo Trigger - Continuous Rotation - WIG-13872 - SparkFun Electronics)](SparkFun Servo Trigger - WIG-13118 - SparkFun Electronics)
