This example shows how to connect to sensors using the SoftwareWire library.
11+
12+
This is an advanced example. You'll need to edit the SparkFunBME280.h file
13+
and uncomment the #include <SoftwareWire.h> line to enable Software I2C.
14+
15+
Since we're using software I2C we can use almost any pins. For this example the
16+
hardware connections:
17+
BME280 -> Arduino
18+
GND -> GND
19+
3.3 -> 3.3
20+
SDA -> 6
21+
SCL -> 7
