This is so, because well be using two Serial Communication ports: one is reserved for the communication between Arduino and the COM port of your laptop and the other is for the communication. As of Arduino 1.0, the library inherits from the Stream functions, making it consistent with other. On the Arduino Mega, SDA is digital pin 20 and SCL is 21. Essentially, you would wire the shared line to both the receive and transmit pins, and when it.

ARDUINO SOFTWARE SERIAL AND WIRE LIBRARY INTERFERENCE DRIVERS
On most Arduino boards, SDA (data line) is on analog input pin 4, and SCL (clock line) is on analog input pin 5. The famous ones, like RS485, utilize special line drivers and differential signalling, but for short distances you can accomplish something similar using the ability of most MCUs, including the Arduinos ATmega, to tristate the serial transmit pin.

It has this syntax: Wire.begin () or Wire.begin (address) If Arduino joins the I2C bus as a master, the method must be called without arguments. Youll also need an Arduino Micro or Leonardo or any Arduino compatible board that has an ATMega 32u4 processor. This library allows you to communicate with I2C / TWI devices. * This code works with MAX30102 + 128x32 OLED i2c + Buzzer and Arduino UNO * It's displays the Average BPM on the screen, with an animation and a buzzer sound * everytime a heart pulse is detected * It's a modified version of the HeartRate library example * Refer to for more details or SurtrTech YouTube channel */ #include //OLED libraries #include #include #include "MAX30105.h" //MAX3010x library #include "heartRate.h" //Heart rate calculating algorithm MAX30105 particleSensor const byte RATE_SIZE = 4 //Increase this for more averaging. The wire library has these methods: wire.begin () used to join the I2C bus as a master or slave.
