I will program your ws2812 ws2811 addressable led system
I turn hardware concepts into working embedded systems
I’m Rakesh, an Embedded Systems & IoT developer turning hardware ideas into reliable working prototypes. I specialize in ESP32, Arduino, C/C++, WS2812/WS2811 pixel LEDs, custom animations, sensors, Wi...
About this Gig
I will develop custom ESP32 and Arduino embedded systems tailored to your project requirements. I can work on sensor-based devices, smart displays, LED matrices, WS2812B/WS2811 pixel systems, IoT automation, wireless control, API/cloud integration, and custom hardware interfaces.
For advanced projects, I can implement FreeRTOS multitasking, non-blocking firmware, RTC fallback, error handling, OTA updates, and performance optimization to create reliable and responsive systems.
Whether you have a concept, circuit, prototype, or partially completed project, I can help turn it into a functional embedded solution with clean, well-structured firmware, hardware integration, wiring guidance, configuration instructions, and documentation.
Includes:
- Custom ESP32 firmware architecture
- Multiple sensors & hardware modules
- LED matrix / WS2812B systems
- Custom displays & interfaces
- Wi-Ficonnectivity
- API / cloud / database integration
- FreeRTOS multitasking
- Advanced automation & control logic
- RTC / offline fallback
- Error handling & recovery
- OTA firmware updates
- Remote configuration where applicable
- wiring & system documentation
- Testing & troubleshooting guidance

FAQ
What information do you need to start my project?
I need your project requirements, ESP32/Arduino board, sensors or modules, display/LED type, desired functions, and any existing code, circuit diagram, or reference images.
Can you work with my existing ESP32 or Arduino code?
Yes. I can modify, debug, optimize, or add new features to your existing firmware.
Can you integrate sensors and different hardware modules?
Yes. I can integrate sensors, displays, relays, motors, WS2812B/WS2811 LEDs, RTC modules, communication modules, and other compatible hardware.
Can you create LED matrix and pixel LED animations?
Yes. I can develop custom animations, effects, patterns, color systems, and control logic for WS2812B/WS2811 and compatible addressable LEDs.
Can you use FreeRTOS for advanced ESP32 projects?
Yes. For suitable projects, I can design multitasking firmware using FreeRTOS, including separate tasks for displays, sensors, networking, and background operations.
Can you provide wiring diagrams and documentation?
Yes. Depending on the package, I can provide pin configuration, wiring guidance, setup instructions, and technical documentation.
Can you implement OTA firmware updates?
Yes. OTA functionality can be included in suitable ESP32 projects, depending on the required update method and system architecture.
Can you troubleshoot my existing hardware project?
Yes. I can help diagnose firmware, communication, display, sensor, timing, connectivity, and integration problems.
Can you build a completely custom project?
Yes. If your project doesn't exactly match a package, contact me before ordering. I can review your requirements and suggest the appropriate package or a custom offer.
