Hi there,
I am a very inexperienced programmer that is having a few errors come up from the attached code. I was hoping for some insight as to how to fix these.
I am using these weather meters:
A one wire temperature sensor to measure temperature and an accelerometer to measure wave weight.
I still have to include the MPU 6050 Accelerometer code, because of the issues I am having with the weather meters. Once those are fixed I will add the rest.
The temperature sensor is working well, with the Particle.Publish function and doing what I require it to do.
I am also looking for help to understand how to create a Particle.Publish line for the Wind Speed and Wind Direction, as I had a teacher help me with the first one, I am unsure how to create ones for these other variables.
The errors I am receiving are below the code.
Any help is greatly appreciated!!
