Quote:I want to send Arduino sensor data to a SQL server, but I do not know how.
I guess you are a beginner because you do the same mistake as every beginner.
Advice: Learn to break your problems in small/simpler parts.
You don't have a single complicated problem, you have a few simple ones.
- to learn how to read data sensors, the principle is the same, whatever you do with that data.
- to learn how to connect to SQL server and trow orders, the principle is the same, whatever data come from.
- how to write some glue code to put everything together. Glue code - Wikipedia
If you Google for your exact problem, you will have almost no answer.
But if you Google each simple problems, you will have heaps of answer because those problems are universal.
