Hey, I’m new to coding in RobotC so if anyone could help me out I would be very grateful. Any resources, links, or videos that have in depth tutorials for everything from motors to sensors (like gyros) will be greatly appreciated. Thanks!
https://renegaderobotics.org/tag/programming/ is a pretty good opener to how some of the sensors work.
One of our teams is coding in RobotC. they have set up a pneumatics system for their intake and shooter. The problem is that they cannot drive and use the pneumatics? The Robot jitters and the pneumatics pulses ? The 2 pneumatics Solenoids will only work when they are actuated by themselves?
If anyone is willing to have a look at our code that would be greatly appreciated. See below:

This is actually something that can’t really be fixed, we used pneumatics in the star-struck game and it did the same thing its just how the robot processes the code. I would honestly avoid pneumatics if i were you there are too many cons outweighing the pros
Please make a dedicated thread for your question in an appropriate channel, making use of the
tag (highlight your code, click the button in the toolbar between the image and quote buttons).This is a very vague claim that seems quite misinformed.
Upon just a cursory code examination, there a number of things that could be done so that “how the robot processes the code” is exactly how the user intends for the robot to process the code.
I will gladly list some such things in the aforementioned dedicated thread (I will not further the derailment of this thread).
Is there any way to code two motors to run simultaneously in C++ in VCS?
Nevermind
