esp8266 test with max30105

ESP8266 tests with max30105 over WeMOS D1-r2 like board

Connection

From SparkFun library of max30105:

Hardware Connections (Breakoutboard to Arduino): -5V = 5V (3.3V is allowed) -GND = GND -SDA = D2 (or SDA in Wemos D1-r2) -SCL = D1 (or SCL) -INT = Not connected

The MAX30105 Breakout can handle 5V or 3.3V I2C logic. We recommend powering the board with 5V but it will also run at 3.3V.
