Sorry for the incredibly late reply but I have finally gotten the IMU soldered and I've ran your code, it suggested that there is still no sensor detected on the I2c bus, I tried the code in step 3 however that ran with a constant temperature of 36.5 degrees Celsius if I remember correctly, which was wildly inaccurate for the conditions in the room I'm testing it in. The code in step 4 printed the area message 'class MPU6050' has no member named 'readTemperature'; did you mean 'getTemperature'? so I have no clue what to do from here.
