Arduino Jobs

Soy aficionado a la impresión 3D y al mundo maker, con conocimientos básicos de Arduino y fabricación DIY. Actualmente estoy dando mis primeros pasos en Fusion 360; hasta ahora he explorado la interfaz y seguido algunos tutoriales sueltos, pero quiero dar un salto de calidad y aprender, desde cero o nivel básico, a modelar piezas funcionales que realmente pueda imprimir y usar en mis proyectos caseros. Mi objetivo no es profesional ni industrial, sino aprender como hobby, de forma práctica y ordenada, para poder avanzar de manera autónoma en el diseño 3D. *Qué quiero aprender: Uso práctico de Fusion 360 desde nivel inicial a básico–medio. Fundamentos de bocetos, restricciones y parámetros. Diseño d...

Necesito un programa en C++ que permita al ESP32 descubrir de forma rápida y fiable las direcciones de todos los esclavos conectados mediante el protocolo MIPI RFFE. El objetivo exclusivo es identificar esos ID; no busco cargar ni probar otros comandos del bus. Planeo compilar el código en ESP-IDF (puedo adaptarlo si prefieres Arduino), pero partiríamos de un proyecto completamente nuevo: no quiero basarme en librerías existentes, sino implementar la lógica desde cero. Si el periférico RFFE hardware del ESP32 no resulta práctico, acepto un enfoque bit-banging siempre que respete los tiempos del estándar. Dispongo de cierta experiencia con MIPI RFFE y podré validar la salida con un analizador lógico; aun así, agr...

I’d like to turn an idea I have into a working wearable: a ring-sized smart touchpad that behaves like a computer mouse. Picture a sleek band you slide onto your finger—tap or swipe on its tiny surface to left-click, right-click, or scroll just as you would on a trackpad. Scope • Design the electronics and enclosure for a ring-form factor. • Implement reliable click and scroll detection on the ring’s touch surface. • Deliver a functioning prototype that pairs over common wireless standards (Bluetooth LE preferred, open to suggestions) and is recognized by a Windows or macOS computer as a standard HID mouse. • Provide firmware, schematic, 3D-printable enclosure files, and clear build/programming instructions so I can reproduce or iterate on the...

Including a small simulation, an IoT setup, and clear documentation.

I have a Raspberry Pi Zero 2 W that will connect to an Arduino / existing MCU system. I need a PyQt (PyQt5/PyQt6) application running on the Raspberry Pi that acts as a display-only dashboard for an automotive device I am manufacturing. The UI must show ~30 sensor indicators (icons + animations), such as CKP/Crank, CMP/Cam, injectors, etc. The Raspberry Pi will receive digital signals via GPIO from my existing device, and the UI must activate/deactivate icons and animations in real time based on those signals. Example: • If an injector signal is ON → show injector “spraying” animation • If OFF → show injector idle icon Same concept for other sensors. Additionally, the UI must display CKP and CMP signals visually (blinking / waveform-style indicator / pul...

Build a Battery-Powered Retail “Jackpot Button” (Arduino + Audio) Project Description We are an Australian food brand, looking for an experienced electronics / Arduino developer to design and build a battery-powered interactive push button for an in-store marketing campaign. Customers press a large mushroom-style button mounted near a freezer or fridge. Each press plays a short sound. After a random number of presses, a jackpot sound plays and the customer wins a prize. This is an initial single-unit prototype, with potential follow-up work for multiple units. ⸻ Required Functionality • Large mushroom head push button (easy to press, durable) • Each press: • Increments an internal counter • Plays a random non-success sound (~5 seconds) • Afte...

Project Description (Academic / Student Project) This is an academic / learning firmware project related to automotive electronics. The objective is to develop STM32 firmware that emulates a rotary position sensor for bench testing and calibration exercises. The firmware will: Receive a position command (0–100%) over CAN Output a corresponding analog voltage using the MCU DAC Periodically transmit a CAN frame reporting the current output value Apply a simple timeout-based failsafe (fixed fallback voltage) This project is intended for: Final-year engineering students Recent graduates Embedded systems learners with STM32 experience Clear technical specifications (CAN IDs, voltage scaling, timing) will be provided. ⚠️ Educational / bench use only ⚠️ No functional safety or ...

Key Requirements: - Select an appropriate small motor - Develop electronics and firmware for precise control using Esp32 - PCB design - Battery selection - Enclosure CAD design enhancement - Ensure high accuracy in movement Ideal Skills and Experience: - Expertise in motor/actuator selection and control - Experience with PCB design electronics and firmware development - Experience with CAD design - Background in industrial machine...

I have an Epson TM-T82IIIL (link below) whose cash-drawer kick-out port sends a short 24 V pulse whenever the drawer opens: I need a tiny MicroPython program for an ESP32 that watches that line, converts the pulse to a safe logic-level signal, and drives a single standard LED. As soon as the pulse is detected the LED should begin blinking and must keep doing so until I press a momentary push-button wired to a free GPIO pin; on that press the LED turns off and the board returns to its idle, waiting state. No other behaviour is required. Please deliver: • MicroPython source (.py) with clear, inline comments • A minimal wiring diagram showing the ESP32 pins, opto-isolation or voltage divider you recommend for the 24 V pulse, the LED and the push-button • A short read...

I need Firmware for ch32v003 chip and looking for a programmer with a physical board in hand (any WCH will do)

I already have working schematic and layout files for two open-source inspired products—an Arduino-compatible board in the UNO form factor and an ESP32 DevKit style module. Before releasing them to U.S. customers, I need a seasoned hardware engineer to give the designs a rigorous once-over focused first and foremost on high reliability, while still keeping manufacturing cost low and leaving the door open for future certification work. Here’s what I expect: • Detailed design review that pinpoints electrical, thermal, and EMC weak points, plus concrete improvement suggestions. • Bill of Materials audit with corrected part numbers, current supplier links, and drop-in alternatives for any components at risk of shortage or EOL. • Clean, production-ready delive...

I need an experienced hardware designer who can turn my concept for a cylindrical, flashlight-style RGBW 'beacon' into a working, weather-resistant prototype. It has to shrug off rain and humidity with an IP-rated enclosure, remain visible in full sun or heavy cloud, and run from a rechargeable battery. Smooth, precise brightness control is critical—I want remote dimming and color mixing over Wi-Fi, not just simple on/off states. Core requirements • Cylindrical housing (roughly flashlight form factor) with a frosted diffuser above the LED stack, all components housed inside the cylinder • High-output RGBW LED module, optics chosen for daytime visibility • On-board Wi-Fi (ESP32 or similar) for wireless control and OTA updates • Rechargeable battery can b...

I’m working on a small ESP8266-based gadget that drives a 0.96" I²C OLED (address 0x3C). The goal is to bring the screen to life with playful eye animations along with some stylish text effects. Where I’m at: • The hardware is wired and running on the standard Adafruit SSD1306 / GFX stack (happy to switch to U8g2 or another lightweight library if it helps). • I already sketched a few eye frames in monochrome bitmap format, but I need additional poses and a clean way to render them in sequence without chewing through ESP8266 memory. What I need from you: 1. Extend my existing bitmap set with new frames/expressions so the eyes feel lively. 2. Write well-structured Arduino code that plays these animations smoothly on the 0.96" display. 3. Add a simpl...

I’m building a compact embedded platform that can simultaneously collect data from temperature, pressure, and motion sensors—plus any other common sensors you feel are appropriate—process that information locally for real-time control, and then push the results out through a robust communication interface. The core of the job is end-to-end: firmware that handles reliable sensor acquisition over I²C/SPI/UART, a control loop that can react in microseconds, and a wired or wireless link (BLE, Wi-Fi, or CAN are all acceptable) to stream logs or accept remote commands. Whether you favour an ARM Cortex-M, ESP32, or another microcontroller is up to you as long as you justify the choice in your response and keep power efficiency in mind. To keep everything transparent, ...
