In this tutorial we will use I2C communication between two arduino boards and send (0 to 127) values to each other by using potentiometer.
Although it is often enough to use a single Arduino to read from a sensor and display the result in the serial window or on an LCD screen, sometimes this is just not enough, and you may want to split the task between 2Arduinos. An example of this might be an Arduino sensing the rot...
I'm using an i2c serial bus for communication between two Arduino (Uno = Master, Due = Slave) and I'm currently experiencing problems while reading data received by the slave. The master sends some data usingWire.write(command). The slave receives it and the handler function...
In this tutorial, we will learn about RS-485 Serial communication between two Arduinos and then demonstrate it by controlling the brightness of the LED connected to a Slave Arduino from Master Arduino by sending ADC values through RS-485 Module. A 10k potentiometer is used to vary ...
The exercise of I2C COMMUNICATION is divided by the following two demos 实验一 Demo 1 两块板子连接的端口需要为SCL与SDA对应连接 SDA 负责数据传输 SCL 负责时钟控制 Uno与Nano的SCL与SDA端口如图所示 The port of connection between these two boards is the respectively corresponding connection of SCL and...
I have found examples of basic arduino to arduino serial communication but have been unable to get those working on ESP32 boards. I am trying to make the same thing work between two ESP32's The two are connected: esp1 esp2 gnd to gnd ...
I2C Communication interfaces between two Arduino boards are also possible. It is used for short-distance communication interfaces and uses the synchronized clock pulse. This I2C Arduino is used while communicating with the other sensors and devices that need to send the information to the Master. ...
Arduino code: this code is provided communication between sensor gy-521 and arduino. I read data by the command "1", after 1000 samples arduino is waited for new command for read data. Arduino code works well in arduino port. #include<Wire.h>constintMPU=0x68;int16_tAcX,A...

You can refer to this ES32 SPI multiple bus example Arduino sketch. By using this sketch, we will perform SPI communication between two Arduino boards in the next section. #include <SPI.h> // Define ALTERNATE_PINS to use non-standard GPIO pins for SPI bus ...
