I am using an arduino uno and the adafruit MCP9808 (https://www.adafruit.com/product/1782)
I followed the tutorial
https://learn.adafruit.com/adafruit-mcp ... ide/wiring
which is not very hard.
When calling the method tempsensor.begin() it fails not being able to get the MCP9808_REG_MANUF_ID.
I tested the wiring and the pins soldering is clean.
is there a way to test MCP9808 to make sure it is working?
Or the component came defective or may be I did something during the soldering of the pin.
How can I trouble shoot this?
Thanks

Re: Cannot get my adafruit MCP9808 to work
When you run the example code what do you get?

Every time the library read a value from one of the register of MCP9808 I get the value 65534.

Re: Cannot get my adafruit MCP9808 to work
When you run the example code "mcp9808test" what do you get? Could you post the code you are running so we can have a look?

Re: Cannot get my adafruit MCP9808 to work
I am running the exact code from mcp9808test.
I think my MCP9808 is dead, but how can I tell if was shipped broken or may be I destroyed it while soldering.
is it possible to destroy it just by soldering it.
Thanks, Fred.

What is the output from the serial monitor when you run the code?I am running the exact code from mcp9808test.
Could you post clear, detailed pictures of both sides of your board showing any soldering you have done and the connections to it?I think my MCP9808 is dead, but how can I tell if was shipped broken or may be I destroyed it while soldering.

Re: Cannot get my adafruit MCP9808 to work
You need to redo the soldering of the header. Take a look at this Soldering Guide
