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...
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 tx2 to rx2 rx2 to tx2 Simple sketches: //transmi...
First, the connection between SCL and SDA is the same as Demo 1. Then the port 2 is INPUT while the port 9 is OUTPUT. Whether the button is pressed, the current flows from port 9 and must return to GND after passing LED, and according to the reception message to control the switch ...
How to use I2C in Arduino: Communication between two Arduino Boards I2C Communication with PIC Microcontroller PIC16F877 Interfacing 16X2 LCD with ESP32 using I2C I2C communication with MSP430 Launchpad Interfacing LCD with NodeMCU without using I2C ...
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 UnoFLAGMIT App Inventor is an intuitive, visual programming environment. This subject proposes key technologies to develop App using AI2 environment that can communicate with Bluetooth module in Arduino Uno. We can send message to control FLAG's innovation car by using these techniques. We...
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...
