Addressable led strip WS2812B controller using Arduino Pro Mini 5V with Voice input

Hi, I have several years of advanced experience in arduino development and 15+ years in electronics/embedded development. I have worked several times with neopixels (WS2812B controller) in different projects. You can find a standard demo I compiled and uploaded to an Arduino UNO: [login to view URL] The video is not very good because of definition and also the brightness of the LEDs... But you can get the picture, I think... I used a neopixel ring because it's what I have handy at the moment, but already worked with neopixel strips (it's all the same, only the physical layout is different). I only need to attach a microphone and take care of sampling, define the maximum threshold to trigger the "random" feature, update each LED color depending on "random" or "normal" state and I think it's done. Have you considered the usage of the microphone breakout board with a digital output with adjustable signal trigger threshold ? This would simplify the arduino programming and would make the system more robust, I think... Here's an example board: [login to view URL] I'll easily add the requirement to configure (through #define statements) the total number of LEDs and number of LEDs per group. Please let me know if you are interested and feel free to contact me for additional info. Best regards, Carlos.

Hello! I am interested in your offer! I have experience in programming (over 10 years) for power electronics with microprocessors PIC (microchip), AVR (ATMEL), STM32 (STeleсtronics) and Arduino's. I recently registered here, and willing to work for a small cost, because I need to improve the rating. Examples of my work you can see in the portfolio Waiting for your reply.

Hi, I hope you are doing well. I have working code for your project, I can complete this project in 2-3 hrs. Looking Forward, Khawaja

hi i am an electrical engineer. i have strong skill set related to Arduino development, i have worked on WS2812B. i can do this project for you. let me know if you are interested and we will discuss the details.

Hello, I'm Alex, an automation engineer. the ws2812b leds are nice to work with. i have done several projects like yours, but with ws2801 led strips. best regards, Alex

Hello I'm Mouaz Imran from Appxone Technologies. Sir I understand your problem, i have read complete description(additional description too). What I have found there is a issue in your code that your calling function have some same variables that cause issue. PM me so i can discuss more about that, if possible please send me picture of this installed hardware. Thanks Regards Mouaz Imran Appxone Technologies.
