I get an error when I just load the following code arduino code.
“Could not find a valid BMP085 sensor, check wiring!”
Is there a way to read the code that is loaded onto a Arduino Nano 3.0. I have a chip that has some code that works that I do not have saved anywhere else but the Nano 3.0
I have another BMP085 on the way
[code]#include <Wire.h>
#include <Adafruit_BMP085.h>
