Need Assist in Programing Flowmeter and temperature sensor to the RaspberryPi (Python)

e14 Contributor
e14 Contributor over 12 years ago

Hey guys i'm new to the community and just starting out with the raspberry pi.

i do have some basic programming experience with C and FORTRAN but python is new to me.

 

I am working on a project that requires tow of the Liquid flow Meter - Plastic 1/2" NPS Threaded (adafruit 828), and six of the Waterproff DS18B20 Digital temperature (adafruit item 381).

 

I am trying to program them into the raspberry Pi in order to record and display each of temperature sensor data in Fahrenheit and each flow meter need to put out instantaneous speed of liquid in Gal / Minutes.

 

Adafruit does have the code for the temperature sensor and the flow meter but the problem is that the code for flowmeter is designed to output the data on a twitter page and i can't make any heads or tails of it. also the two programs need to be able to put together in to a single file.

 

please help.

    What is the problem with this second code ?

     

    The indentation is lost when pasting code here, and unfortunately it's hard to follow unindented Python code.

    I do apologize, I didn't realize that copy and paste messed with the indentation.

    the problem is that only output i see to the screen is the 'error' instead of seeing the frequency. If i can get the frequency i should be able to make it work with that.

    Perhaps you want 'and' rather than '&'.  The latter is doing a bitwise AND where I think you want a logical AND?
