Let us demonstrate an example of RS485 serial data transfer between two Arduino boards using the MAX485 TTL to RS-485 module. Our aim will be to send ADC values from the master Arduino connected with a potentiometer through the RS485 module to the slave Arduino. The slave Arduino will be ...
In this tutorial, we will perform UART or serial communication between two ESP32 boards using UART hardware library ofArduino IDE. To debug and program ESP32 using a USB port, the serial port which is known as Universal Asynchronous Receiver/Transmitter (UART) Communication is used. For most s...
Re: BT Classic communication between two ESP32 PostbyTianhao»Fri Aug 31, 2018 10:47 am Could you test the SPP demos (receiver and initiator) in official ESP-IDF master branch or release/v3.1 or other branches? All of the same problems happened with Arduino platform?
The objective of this esp32 tutorial is to explain how to get started with the BluetoothSerial ESP32 library, in order to send data to a emulated Serial connection, operating over Bluetooth classic. At the time of writing, the mentionedlibraryhad just been added to the ESP32 Arduino core. ...
Communicate between Arduino and Unity easily ! Built for simplicity, stability optimization. Uduino is the most reliable way to merge real-time application and physical experience. IMPORTANT: To upgrade from version 2.0, please remove the /Uduino/ folder before importing the new version....

Configuration and Usage: #include<OpenTherm.h> You have to choose 2 controller GPIO pins which will be used for communication and connected toOpenTherm Adapter. Controller(Arduino/ESP8266) input pin should support interrupts. Controller output pin should be connected to OpenTherm Adapter input pin an...
