I hoping someone can help me out with some programming. I have a Micro Maestro 6-Channel USB Servo Controller. I have a push button on channel 0. I have a Continuous Rotation Servo on Channel 1. The servo position for off is 1492. This is what I’d like to do
Press the button
Wait 3 seconds
Spin the servo 360 degrees, direction doesn’t matter, then stop the servo.
Wait for the button to be pushed again
Wait 3 seconds
Spin the servo 360 degrees, direction doesn’t matter then stop the servo.
And so on
Hi Guys. I can’t find the guy who helped me with my Iron Man programming so if anyone can help with 360 degree program that’d be awesome. .
I’ve been asked for the code for the Ironman helmet. Here it is. As I mentioned an acquaintance wrote this and I paid him for it. The servers had to run in mirror opposite directions but together because of how they were mounted.
Operation
The start position is always “visor up, eyes and Arc reactor off ”
Press the button to run the servos to close the visor.
Visor closed “then” the Arc reactor lights up
then the lights in the eyes flicker a little then stay on.
Press the button again to run the servos to open the visor.
At the same time the lights in the eyes flicker a little then turn off.
Visor open
Then the Arc reactor turns off
This is the start position

I am not sure I understand what you are asking. Did you want the script you posted to be modified to include the functionality you mentioned in your first post?
Also, it is typically more difficult to turn the continuous rotation servos exactly 360° since you do not have position feedback in most cases. You will most likely have to send them a command to rotate, and time how long a full rotation takes. Then, you can delay for that amount of time before sending a command to stop the rotation.
No I was just posting the Ironman script for those interested.
For my new project I modified a servo to spin 360. You’re 100 percent right on the positioning. Without the pot the program has no way of knowing the location. I’m new to all this. I did get it working though. I fumbled through the examples and used the sequence function. There is prolly a bunch of code in this that isn’t required but it works and I’ll mess with it after Halloween.
goto main_loop # Run the main loop when the script starts (see below).
# This subroutine returns 1 if the button is pressed, 0 otherwise.
# To convert the input value (0-1023) to a digital value (0 or 1) representing
# the state of the button, we make a comparison to an arbitrary threshold (500).
# This subroutine puts a logical value of 1 or a 0 on the stack, depending
# on whether the button is pressed or not.

# This subroutine uses the BUTTON subroutine above to wait for a button press,
