MLX90614 SCL to Arduino SDA (SCL pin for I2C) 4. MAX30102 Pulse Oximeter and Heart Rate Sensor: Role: Measures blood oxygen saturation (SpO2) and heart rate. Functions: Uses light-based technology to ...

The i2C uses two lines to send and receive data. We use Serial Clock Pin (SCL) for the synchronous clock and Serial Data Pin (SDA) for the data transfer. We can have 128 Multiple master and slave ...

An Arduino has one one SDA pin and one SCL pin to communicate via I2C. We need to figure out a way to assign each ToF a different address so they can all communicate via the same pin.
