How do I transfer numbers from one Arduino to another?

How to send numbers from one Arduino to another using Serial

1. Send some sort of “start number” delimiter (in this example, the “<” character).
2. “Print” the number, which turns it into a string of ASCII characters.
3. Send some sort of “end number” delimiter (in this example, the “>” character).

What does I2C mean in an Arduino tutorial?

Note: Although we will be using Arduino Uno in this tutorial. But concepts and coding examples will work on other Arduino boards such as Arduino Mega, nano, micro, etc. I2C means Inter-integrated circuit communication protocol. It is a 2-wire serial communication protocol for short range data transfer applications.

How does Arduino communicate data from multiple sensors?

Arduino communicating data from multiple sensors to a neighbor Arduino for display. A previous project dealt with connecting two Arduino’s to each other via serial communication where Arduino #1 reads a temperature sensor and transmits the data via one of three available serial communication protocols to Arduino #2.

Which is a slave device on the Arduino I2C bus?

In this picture, Arduino and Raspberry Pi are acting as a master and MPU6050, sensor devices as a slave. I2C bus consists of multiple devices such as slave and master Slave devices. Each slave devices has unique address that is utilized to recognize the device on the bus.

How is the I2C bus used in microcontrollers?

Devices that want to communicate with each connects through an I2C bus. I2C bus supports multiple slave devices and multiple master devices. Many Sensors use this serial communication protocol to transfer their data to microcontrollers or through this protocol different slave circuits are able to communication with master circuits.
