    In this tutorial with Wemos ESP8266 Wroom D1 Mini WiFi Module 18650 Battery Holder Onboard, we'll use an application from the smartphone "Blynk" to control the Arduino Wemos D1 (ESP8266) with LED Traffic Light Module.


    item needed:

    • Breadboard
    • Wemos ESP8266 Wroom D1 Mini WiFi Module 18650 Battery Holder Onboard
    • Jumper wires male to female
    • LED Traffic Light Module ( you can also use base LEDs )
    • micro USB
    • Smartphone (You need to download "Blynk" from Play Store/iStore)
    • Ultrafire 3.7V 1100mAh Li-Ion Battery (if needed


    Connections of the circuit:

    To get the example code from the Blynk you need to download the library from the Blynk website.

    https://www.blynk.cc/getting-started/

    Follow these steps:

    1. Select "Download Blynk Library".
    2. Select "Blynk_Release_v0.5.4.zip".
    3. Extract the files and copy both of the files (libraries, tools).
    4. Open Arduino IDE go to [Files => Preferences] find the files that appear on the "Sketchbooks location".
    5. Open the Arduino file and paste both of the files you've copied.
    6. Then, open your Arduino IDE, go to [Files => Examples => Blynk => Boards Wifi =>Standalone] for the example code.
