Outputting Accelerometer Data to blynk app

Need Help With My Project
1

I had this program working at one point but now I’m not getting any data displaying on the blynk app. If somebody has a suggestion that would be great. Thanks.

Code snippets should be formatted. Please edit your initial post:

How to do that:

?format=2500w960×540 


 ``` cpp <--put 3 backticks BEFORE your code starts  ("cpp" means C++ language) 

   //Put your code here
   //..................
   //..................

 ``` <--insert 3 backticks AFTER your code

**This makes your code readable and with highlighted syntax, like this

↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓

//comment goes here 
void helloWorld() { 
   String message =  "hello" + "world"; 
}

@nlasky And now edit out your SSID and password before we all use up your bandwidth :stuck_out_tongue: CanHasFreeWifiNow?

And Auth code, just because… @Jamin has ideas :stuck_out_tongue:

@nlasky
how you calculate Rotations?

First, this is an old topic. 2nd, you don’t do that with an Accelerometer.
