Feb 8, 2016 · what do i have to modify so that the first arduino automatically send the data (like an analog value) to the other arduino? You would have your first arduino make a request to your second arduino. This means that your second arduino acts as a server, with an internet address.

Oct 21, 2019 · A common way is to run a web server on the PC and create a page there that you can hit with a GET request from the Arduino, including sensor data as parameters. Or you can send UDP packets with the sensor data and write something on the PC to grab the data. MQTT is another popular way to share data.

Apr 9, 2018 · Whether you use an Ethernet shield or an ESP8266 to do wireless, the process of making a GET request to a server (Hey, server, run this script to use this data) is the same. You need to develop the scripts on the server that take the data and shred it.

Jan 9, 2019 · Enable communication between an Arduino and Web Browser using the Open Sound Control (OSC) protocol. This article explains how to enable bidirectional, Open Sound Control (OSC) communication between an Arduino and web browser. We'll be using the buttons in the browser to send OSC messages to Processing.

May 16, 2016 · In this tutorial, we are building a program to Send Data to Web server or cloud using Arduino and Wi-Fi module. For this we first need an IP address of either Global or Local server, here for the ease and demonstration purpose, we are using Local Server.

Jun 28, 2017 · For Sending Data to SparkFun Server, we need to interface Keypad and GSM module to Arduino. In this project we have used Arduino to taking input string from the keypad and sending commands to GSM/GPRS module. GSM/GPRS is used to communicate with the Internet for sending data to the Sparkfun server.

Mar 16, 2016 · In this tutorial, an Arduino and Ethernet shield are used to send data over the Internet which is then logged and displayed in a graph using an external IoT (Internet of Things) service called ThingSpeak.

Apr 22, 2019 · Wireless transfer data to an Arduino by way of 433MHz transmitter/receiver modules by using the RH_ASK library.

Connect an Arduino to the IoT cloud using JSON and MQTT. Here's a simple project for you to try, showing a number of things: read in analog data (in this project we'll use a light level detector) connect to an MQTT broker in the cloud; publish data in the form of a JSON object to the MQTT broker; view the light-level data on an Assetwolf portal.

May 14, 2014 · If you just need the sensor Arduino to send sensor data wirelessly to some kind of base station, that's much easier. There are a few examples of wireless modules that can send data wirelessly, and the receiving Arduino can use a …
