In this project you’ll create a standalone web server with an ESP32 that can toggle two LEDs using the Arduino IDE programming environment. If you want to learn more about the ESP32 dev board, read my Getting Started Guide with ESP32.  First, watch the video demonstration below Preparing the ESP32 board in Arduino IDE There’s an add-on for the Arduino IDE that allows you to program the ESP32 using the Ardui ...

This project is a modification of my previous Bluetooth-enabled LED matrix display project, which used 8×64 monochromatic LED matrix (total 512 LEDs) for displaying scrolling text message. The original project used Bluetooth for display data transfer from a smartphone, but this one now uses Wifi. The display message is sent through web browser to a ESP8266 module that is configured as a web-server. No Ardui ...

Time to get Pavlovian on your cat! Story If you ever tried to train a cat, you know how hard it is. Cats are their own masters, but now you have the chance to let the cats do your bidding using this IoT-enabled device. Welcome to Pavlov's Cat Experiment! In this project, you will learn how to teach your cat when it is (and isn't) dinner time using nothing but the components in the MKR IoT Bundle and some ca ...

In this project you’re going to monitor the status of a door using an ESP8266. The goal of this project is to show the endless possibilities that this $4 WiFi module offers when integrates with a free platform that I’m about to show you. Before continue reading this project, please complete the following tutorials or use them as a reference: How to get started with the ESP8266 How to Install the ESP8266 Boa ...

This little Instructable will show you how to use a 320x240 pixel LCD screen connected to an Arduino Uno with a network shield too, to show stats for Youtube channels. I created this as I wanted to see how many subscribers and views I had on my channels without having to check Youtube :) The stats update on the LCD screen every minute using the google api. You will need the following: Arduino Uno Arduino Et ...

INTRODUCTION In this project, we will learn the basics of Transmission Control Protocol (TCP) and how to communicate to a webserver over TCP. We will request and receive packets from the Google web server using the above communication protocol. The 4Duino display is used to print the status of the connection and the received information for debugging purposes. Transfer of Data over Internet The 2 most commo ...

There are but a few things better than (succesfully) programming and using your Arduino. Surely one of those things is using your ESP8266 as an Arduino with WiFi! In this instructable I will show you an EASY way to get the ESP8266 working as a web server AND accessing that server from anywhere (over the internet) Also if you find this instructable interesting, perhaps you'll like some of my others: EASY Ard ...

Consider this the "Blinky LED" of the anduinoWiFi shield! Things used in this project Hardware components Andium Anduino WiFi × 1 Arduino Due × 1 Arduino Zero & Genuino Zero × 1 Software apps and online services Arduino IDE Story Motivation Implementing an IoT prototype utilizing an Arduino that doesn't natively support WiFi can be cumbersome. Sure there are some pretty good options for native support. ...

Introduction On 31 August 2015 I got the new WIZnet platform board, the WIZwiki-W7500 that is based on a Cortex-M0 cpu at 48MHz with 128 kBytes of flash memory and 48 kBytes of RAM shared with the hardwired TCP/IP core. The RAM amount used by the TCP/IP core can be upto 32 kBytes leaving the rest 16 kBytes to the user (32 + 16 = 48 kBytes of RAM). The W7500 is a 3.3V device but according to the WIZnet the b ...

If you want to learn more about the ESP8266 module, first read my Getting Started Guide for the ESP8266 WiFi Module. In this project you’ll create a standalone web server with an ESP8266 that can toggle two LEDs. Why flashing your ESP8266 module with NodeMCU? NodeMCU is a firmware that allows you to program the ESP8266 modules with LUA script. And you’ll find it very similar to the way you program your Ardu ...

This project consists of two temperatures that are measured by the Arduino using two MCP9700 temperature sensors An Arduino Uno and Ethernet shield are set up as a web server that hosts a web page to display the two temperatures on two gauges. The web page is stored on a SD card that is plugged into the micro SD card socket on the Ethernet shield. A web browser is used to display the two temperature gauges ...
