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...
In our previous tutorials, we have learned about SPI and I2C communication between two Arduino boards. In this tutorial we will replace one Arduino board with the Blue Pill board that is STM32F103C8 and will communicate with the Arduino board using SPI bus. In this STM32 SPI Example, we ...
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 SDA SDA is in charge of the data transmission SCL is in charge of the clock control The SCL and SDA port of Uno and Nano show as the picture Arduino Uno ...
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 ...
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. ...

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 ...
Parallel connection between the Arduino and peripherals via input/output ports is the ideal solution for shorter distances up to several meters. However, in other cases when it is necessary to establish communication between two devices for longer distances it is not possible to use parallel ...
I have a problem making LoRa connection between MKR WAN 1300 and WEMOS D1 mini EDP32 boards. I've connected the WEMOS D1 mini ESP32 to LoRa Grove module (868 MHz). The sender code is working fine, but the receiver code is not giving me the output I'm looking for. I changed the...
