All the print txt are called sensor 2 I fixed that

As a note how hard is it to create an UI in Python. Perhaps I can create a basic system so I can test a theoretical rocket.

Adafruit sells Micropython circuitboards. Same concept as Arduino but programmable with (a stripped down version of) Python. Worth looking into, they also have a very active community.

Not overly difficult.

I assume you're missing some packages.

Yes

how can I create a UI for "Mission Control" sort of thing for testing this code?

Sorry, couldn't help myself. It's a huge topic, and you're better off reading an actual tutorial rather than one of us trying to write one in a forum post.

How did that program/service work?

My deltav.py program, or lmgtfy.com?

I was joking but for my own curiosity I guess both of them

Ok back again. It occurred to me that since the sensors will need to adjust the course of the rocket more than once that my old code would be insufficient because it would only check for corrections at the moment of launch. Thus at the beginning of each code section I added 

while 1>0

Since this is always true it is an infinite loop. 

I tested this however but only the first sensor fired correctly. Furthermore it seemed like the rest of the program halted.

 

Here is the full code:

Yeah, you want just one loop at the bottom containing just the calls to the functions. The part where you define each function doesn't need to be in the loop.

Ok let me try it for my own knowledge why is this the way the logic works?

The program starts at the top and only does one thing at a time. If you tell it to enter an infinite loop, it will never get to the things that are after that loop.

Not surprising. Without the parentheses it won't call the functions.

remember the values for the functions need to be empty

Presumably it would complain about b1, b2, b3, and b4 not being defined for that.

[Cheif Operations Director]

I still got the message for sensor #1 only even though I put it last

I need to call the function without inputing a value. The whole point is that it will reassess if their is a change to the value

Each of those bold lines is also going to be an infinite loop, so it's getting stuck there. Try changing them back to 'if' statements.

Ok I fixed that. It still is demanding a value for b1 b2 b3 b4

I tried testing it will numbers and it works as intended but the numbers will be inputed from a sensor in flight thus I can not when this program is actually running type in the numbers

[HebaruSan]

Just now, Cheif Operations Director said:

Yeah, don't use b1, b2, b3, and b4.  Give a number.

[Cheif Operations Director]

Just now, HebaruSan said:

Again I can not.

Remember this is an RCS System that is automated. If a sensor is trigger (meaning the rocket off course) it inputs a value greater than 1 into those b places. This means that I can not write an number into a code because that number is determined by things like the wind on the day of launch. 

I tested it with numbers and it worked as intended but as I stated above that is just to ensure success of the system the numbers need to come from a sensor.
