NodeMCU ESP2866 WS2812B LED managment -- 2

Based on a functional prototype and a first unachieved project, I am looking for help to create a finalized version of the whole project and make all working together. Most of tasks are done but we should implement the led logical function and debugging/testing. Global principle and functions : In a stairs case : 2 PIR sensor (up and bottom position) a digital led strip ( WS2812B ) ligthing gradually dot after dot a stairs case in the travel way by a selected effect and color . A standby effect is optionally applied after a delay. Video of the actual prototype : [login to view URL] Hardware principle (Fig 1) : 1 Nodemcu , 2 PIR sensor, 1 LDR sensor, 1 WS2812B Addressable led strip Software functionalities : Based on Arduino IDE (arduino-esp8266) Deploy a webpage based on a captive portal on the ESP2866 than act as a access point. Fig 2 ( connect to the ESP2866 wifi, open a webpage, any request will redirect to the configuration page) This webpage ( I will provide the UI) need to configure all the parameters as described below (number of steps, ....) The webpage is available by any request on the wifi network the module ( captive portal) The ESP need to work as both WIFI mode ( AP and STA ) AP : Povide a wifi to give an access to the end-user to configure the module STA : Provide a way to update the code of the ESP over OTA , ensure a way to upgrade the code easily Parameters and configuration needed : - Number of steps - Led per steps - automatic calculation of theses var - pins configuration selections - colors selection for effects - travel up effect selection - travel down effect selection - closing effects selection - idle effects selection - Implementation of Idle mode selection activation/deactivation( after a delay, activation of a the selectable idle mode) - Implementation of global delays/speed ( down way speed, up way speed, idle activation delay,...) - Adjustable LDR sensivity value ( this is important to define the activation threshold) - Implement LDR watchdog ( to avoid out going out of loop in case of shadow/light variation during cycle) - All these parameter (config) need to be stored (power lost) - OTA update functionalities The WS2812B function are handled by Adafruit NeoPixel library, also all effect can be based on the existing library WS2812FX !! I will do my best to help you in this job with my capabilities . But the project need to meet all requirement before any payments, if you are unable to handle all the requirements, please don't apply to this job. !! !! The whole project will be under Non-disclosure Agreement !!
