Hi I am an embedded systems engineer with over 16 years of experience. I have extensive experience designing microcontroller based control boards for actuators, sensor measurement, displays, WiFi connectivity, and full consumer grade products from concept through prototype and production. For your smart actuator board, I can help with the electronics architecture, MCU/driver selection, pressure and temperature sensor integration, LED screen menu/settings, firmware for position control, and the WiFi interface needed for app connectivity. My approach would be to first confirm the rotary actuator type, voltage/current, feedback method, pressure/temperature ranges, and whether the mobile app already exists or needs a simple protocol defined, then move into schematic/PCB design, firmware, and bench testing logic. Relevant projects cannot be shared publicly, but I can show examples privately where allowed. I can also support firmware tuning and app communication testing after the hardware design is ready. Please contact me to discuss details.

This is a pretty straightforward embedded control setup where a compact board is coordinating actuator positioning while continuously reading pressure and temperature, then exposing those controls both on-device and through WiFi. I’d start by choosing an ESP32 for native WiFi, then match it with the actuator driver and select pressure/temperature sensors based on required accuracy. Firmware-wise, I’d implement a simple control loop for positioning, periodic sensor sampling, a preset system stored in flash, and an LED screen menu for adjusting or selecting modes directly on the board. For WiFi, I’d expose either a lightweight REST interface or WebSocket stream so an app can both push new presets and read live state. Main things I’d guard against are sensor noise, actuator overshoot, WiFi dropouts, and making sure the system always falls back to a safe default position if communication fails. Before I proceed, I’d like to confirm the actuator type and pressure/temperature ranges to size components correctly.

Hi! A rotary actuator controller with WiFi, live sensor monitoring, and a display is a well-defined ESP32-S3 build — the S3 variant specifically, because the extra SRAM headroom handles display buffering and the control loop simultaneously without the memory pressure you'd hit on the base ESP32. On a similar project I built a closed-loop position controller using an ESP32-S3 with a brushless DC motor, integrating a real-time PID loop, SPI sensor interface, and a WebSocket-based WiFi connection to a mobile dashboard. The hardest part wasn't the firmware — it was getting the feedback sensor architecture right so the system held position accurately under varying mechanical load. That's the exact challenge at the core of your build. One component worth specifying early: rather than a traditional quadrature encoder, consider the AS5048A magnetic position sensor — 14-bit absolute position (0.022° resolution) over SPI at under $3/unit. It eliminates the homing sequence on power-up entirely and keeps the system accurate through power loss, which matters significantly if your actuator is holding a set position when the controller restarts. I can share my previous work also as i am not able to share it here. Thanks Regards

I can design and develop the embedded control system for your rotary actuator board, including sensor integration, WiFi connectivity, and an LED-based control interface. The system will be built around a suitable microcontroller (such as ESP32 or similar) to handle actuator positioning, real-time control logic, and communication with pressure and temperature sensors. I will implement stable control algorithms to ensure accurate and repeatable actuator movement based on pre-programmed settings stored on the device. For monitoring, I will integrate pressure and temperature sensors with proper calibration handling and real-time data processing. The LED screen will provide a simple UI for selecting presets, viewing live sensor values, and adjusting configuration parameters directly on the device. WiFi connectivity will be implemented for app integration, allowing remote monitoring and control through a lightweight API or mobile interface. The architecture will be designed so the device can later scale with additional features such as OTA updates or expanded sensor inputs. The firmware will be structured, well-documented, and modular so it can be easily extended or maintained. I will also guide you on hardware selection if needed and ensure stable communication between all components.
