NeoPixel Web Server
1. Install Arduino IDE software. Not the web one. https://www.arduino.cc/en/Main/Software
2. Install the NodeMCU software using the instructions on this page https://randomnerdtutorials.com/how-to-install-esp8266-board-arduino-ide/
- On step 5, select the current version (v2.4.2 at the time of this workshop, December 2018).
- On step 6, select the NodeMCU 1.0 (ESP-12E Module) board for this workshop.
3. Install the FASTLED library
- Select Arduino->sketch->include library->manage libraries
- Search for FASTLED and install (version 3.2.1 at the time of this workshop, December 2018).
4. Download the arduino software for the fastled webserver https://github.com/jasoncoon/esp8266-fastled-webserver
- Click the "Clone or download" button and download the zip. Save this zip file on your desktop or in the documents folder
- Right click to unzip the software
- Rename the folder to "esp8266-fastled-webserver" (removing the "-master" from the default name).
5. Navigate to the folder and run the esp8266-fastled-webserver.ino file
- Find the section that starts with #include "FSBrowser.h" and replace that section with this:
#include "FSBrowser.h" #define DATA_PIN 5 //LVL1 change this! This is D5 #define LED_TYPE WS2811 #define COLOR_ORDER RGB #define NUM_LEDS 30 //change this! #define MILLI_AMPS 2000 // IMPORTANT: set the max milli-Amps of your power supply (4A = 4000mA) #define FRAMES_PER_SECOND 120 // here you can control the speed. With the Access Point / Web Server the animations run a bit slower. //LVL1 change this to true! const bool apMode = true; //LVL1 Comment this secrets.h //#include "Secrets.h" // this file is intentionally not included in the sketch, so nobody accidentally commits their secret information. // create a Secrets.h file with the following: // AP mode password //LVL1 uncomment this! const char WiFiAPPSK = "your-password"; // Wi-Fi network to connect to (if not in AP mode) //LVL1 uncomment this! char* ssid = "your-ssid"; char* password = "your-password";
- Save the changes.
6. Install the Arduino ESP8266FS tool from http://esp8266.github.io/Arduino/versions/2.3.0/doc/filesystem.html#uploading-files-to-file-system
7. In the Arduino IDE select Tools->ESP8266 Sketch Data Upload.
