This is a small project of mine, an LED strip powered by a NodeMCU 1.0 (ESP-12E Module) board, and using Blynk as a backend.

Make sure to fill out src/secrets.h, as well as all the LED strip configurations in src/main.cpp if you want to use this with your own strip!

With Visual Studio Code

• Open Visual Studio Code (other code editors may not work properly)
• Install the PlatformIO extension from the marketplace
• Once installed, restart VS Code, and find the PlatformIO icon on the sidebar
• Find Miscellanceous > Clone Git Project
• Clone the project into your local workspace
• Open a terminal window in the cloned repository root
• Do git submodule update --init
• Make sure lib/Blynk is not empty
• Fine-tune the main.cpp and secrets.h to your own preferences and hardware
• Install the dependencies in the PlatformIO Library Manager
• Build the project or upload it if you have a ESP8266 board connected

With Arduino IDE

• Make sure you have installed the necessary tools for ESP8266
• Clone the repository locally with the --recurse-submodules flag: git clone https://github.com/kerichdev/esp8266ledstrip --recurse-submodules
• Open main.cpp and secrets.h
• In Tools > Board: Choose NodeMCU 1.0 (ESP-12E Module); Upload Speed: 115200; CPU Frequency: 80 MHz
• Using the Arduino IDE Library Manager, install the FastLED lubrary. Latest version should work, but in case of issues, fallback to [email protected]
• Fine-tune the main.cpp and secrets.h to your own preferences and hardware
• Build or Upload the sketch to your board

• The project is intended for 3-pin addressable LED strips: 5V, GND and DI (Data In, but name may vary)
• Make sure the LED strip has its own power supply, and is not connected to ESP8266's 3.3V/VIN pin
• Fill out the correct hardware info about your strip, like the amount of pins

• Create a project with the following template
• Copy the token and paste it in the secrets.h file, as well as the template ID

• You can make whatever integration you like, in fact, all you need to do to connect the strip, is use a webhook/web request as an action, with the following settings:
  • URL: https://(server_region).blynk.cloud/external/api/update?token=(your_blynk_token)&(virtual_pin)=(value)
  • Method: GET
  • Content type: (Please select, aka don't change)
  • Additional Headers: (leave empty)
  • Body: (leave empty)

You can find your server region in the right bottom corner of your blynk dashboard. The virtual pins and their possible values are all present in the template.
