In this video, I show how to connect an ESP8266 to the Arduino Mega 2560, and I send data to my phone which is running the Blynk app. I can also control an LED from the Blynk app. This tutorial assumes that you already know how to create simple Arduino projects. Aside from that, no special skills are needed. • Yes, you really DO need an external 3.3V supply to make this circuit work. Or you need an adapter like the one I use in the video. The 3.3V supply from the Arduino Mega does not provide enough current to run the ESP module. • If you want to know how to connect an Arduino Uno to an ESP-01, watch my sequel video: • • Arduino+ESP8266 Follow Up Video (and ... • This is a pretty long video, so I have included a table of contents below: • 0:00 Introduction • 1:54 Project Hardware • 8:38 Download AT Command firmware for the ESP8266 • 12:53 Download the app to flash the firmware to the ESP8266 • 16:42 Wiring up the circuit to flash the ESP8266 • 19:17 Flashing the AT Command firmware to the ESP8266 • 24:01 Wiring up the Arduino Mega 2560 + ESP8266 • 27:05 Setting up the Blynk app to send and received data • 33:17 Write Arduino code for the LED and millis • 38:46 Confirm Wifi is working and connected to the Blynk cloud server • 39:19 Confirm the LED button works and Millis is displayed • 39:49 Add code to run the temperature sensor and push data to the Blynk app • 43:18 Confirm the temperature data is being sent to the phone • 44:16 Conclusion - Bye! • There are several websites that I use in the video. The links are below: • This is the first link I show in the video. It takes you to the documentation page of the Blynk website. • http://docs.blynk.cc/#hardware-set-up... • This is the link to get the AT_Command firmware • https://github.com/Edragon/esp_firmwa... • This is the link to get the flasher app that I used in the video: • https://drive.google.com/file/d/1frCA... • This page shows an example sketch for the DS18b20 sensor: • https://www.sunfounder.com/learn/Sens... • The Arduino sketch (sketch_nov25a.ino) shown near the end of the video can be found here: • https://drive.google.com/drive/folder... • ******************** • This project requires certain libraries to be loaded into your Arduino IDE. To get the ESP8266 and Blynk libraries, go to this site: • http://help.blynk.cc/en/articles/5121... • … click on Download Blynk Library , and follow the instructions • The temperature sensor used in this video requires two libraries that can be downloaded from SunFounder. The zip folder can be found here: • https://www.sunfounder.com/learn/down... • Open the zip folder and navigate to find… • \\Sensor_Kit_V2.0_for_Arduino.zip\\Sensor Kit V2.0 for Arduino\\Library\\Ds18b20 • … and… • \\Sensor_Kit_V2.0_for_Arduino.zip\\Sensor Kit V2.0 for Arduino\\Library\\OneWire • Copy those two library folders into your Arduino library folder. • **********************
