ESP-RGB-Controller

Tiny ESP8266-based RGB LED controller

Board Hardware

Located in the root directory

Included is the kicad project for the PCB. It's very simple and requires minimal parts. An included BOM.txt gives part numbers used for my assemblies. However, feel free to substitute parts as you see fit.

Board Firmware

Located in the SW-Arduino Directory

The MCU is an AtMega328P in 32-TQFP package. You will need an ISP tool to flash the firmware, such as a USBTinyISP or an Arduino flashed as an ISP.

The firmware was designed to run on the Minicore Arduino platform. You will need to add this to your boards manager and install it in your Arduino IDE. The following settings are used to compile and flash the firmware:

Board: AtMega328
Clock: Internal 8MHz
BOD: 2.7V
EEPROM: EEPROM retained
Compiler LTO: LTO Disabled
Variant: 328P/PA
Bootloader: No Bootloader

You will also need the WifiEspAt library for Arduino, and will need to edit the Wifi login credentials to match your wifi network. Otherwise, it should be plug and play with up-to-date ESP-01 modules.

Note: You will need to update your ESP-01 modules to AT version 2.1 or greater. See the following page on firmware versions from the WifiESPAt library

A minor overview of the features of this firmware:

Recalls last state on power-up, useful if power is interrupted
Reports the current setting in a small webpage when the GET request is recieved, useful for status checking

Control the lights!

GET Requests

The simplest method of control is through your browser, with a simple HTTP GET request like so:

http://<ip.address>?rgb=255,255,255

This will set all three color channels to full brightness.

Controller App

Locategd in SW-TrayTool

You can build the C# Windows Forms app for a slightly more robust control system. The tool includes provisions for multiple controllers and presets, as well as a tray icon for controlling lights in a nice clean way.
