So when i run my code without the blynk interface commands it works perfectly fine, but when i run the blynk.begin command it breaks all my readings and the out put is 0 (should be 2800). I believe it has something to do with the baud rate of blynk needed to be set differently than the serial output but still confused why output would be altered. When i comment out the begin command works perfectly fine although not connected to blynk…
If someone could direct me to an article that better explains this or offer a simple fix i can copy in that would be great!
