Arduino Jobs

Tengo un firmware para ESP32 escrito en C/C++ que ya funciona, pero requiere algunos retoques. Busco a alguien con probada experiencia en ESP32 y en programación C/C++ que pueda: • Revisar el código existente, localizar los puntos débiles y optimizar lo necesario. • Modificar las funciones de control que indicaré —son cambios pequeños pero precisos— sin alterar el resto de la lógica. • Incorporar los ajustes adicionales que entregaré al inicio y verificar, con pruebas reales sobre placa, que todo sigue estable. Entrego el proyecto actual y las instrucciones detalladas tan pronto comencemos. Es un trabajo sencillo, pensado para quien conozca bien el SDK de Espressif, FreeRTOS y el flujo de compilación...

Necesito un modelo funcional en TinkerCAD que represente una estación automatizada de control de nivel de tanque. El sistema debe: • Utilizar un sensor de presión para leer el nivel. • Activar un relevador que encienda una bomba (motor) cuando el nivel baje del umbral configurado. • Mostrar el estado mediante un LED RGB: rojo cuando la bomba está activa, azul cuando está inactiva y verde cuando el nivel se encuentra dentro del rango deseado (modo espera). Entrego el umbral inicial, pero quiero que quede documentado dónde ajustarlo en el código Arduino. El proyecto final debe incluir: 1. Esquema de cableado completo y limpio dentro de TinkerCAD. 2. Código Arduino claramente comentado. 3. Enlace público al c...

I’m building an industrial-grade robotic setup and need a sharp embedded-systems mind to move the control electronics from concept to reliable hardware-in-the-loop operation. The work centres on firmware that drives motors, interprets sensor data and communicates over CAN bus or OBD-II–style diagnostics. Most of the prototyping will happen on Arduino or ESP32 boards before we freeze the design onto a custom PCB, so familiarity with Altium Designer or KiCad for schematic capture and layout is essential. Here’s how I see the collaboration flowing: • Translate high-level motion requirements into C/C++ firmware with clean, well-commented code. • Select, integrate and tune motor drivers, encoders and safety interlocks so the robot meets industrial-speed repeatab...

I have an Allen-Bradley CompactLogix processor installed at my facility in Ridgefield, NJ 07657 and I need a ladder-logic program that fully automates our conveyor line system. The goal is straightforward: once the operator presses START the line should sequence itself, react to its sensors, and shut down safely on faults or an E-Stop, all while remaining easy to troubleshoot. Hardware and software already on hand: 1- allen bradley 5069 l330er • CompactLogix controller with standard 24 V DC I/O cards • A mix of photo-eyes, limit switches and VFD-driven motors • Studio 5000 Logix Designer for programming What I expect from you • A clean, well-commented .ACD project file written in ladder logic • Tag database and I/O map that match my wiring • Brief...

I need to setup a VPS ready and Home Assistant. My next step is to add a rock-solid MQTT layer so I can trigger relay modules through voice commands issued from Amazon Alexa, Google Assistant, and Apple Siri. The relays must respond to simple ON/OFF requests and support dimming where hardware allows. Here’s what I need you to handle: • Recommend and install a production-grade MQTT broker on the VPS, configure secure remote access (SSL/TLS and user auth) and verify message flow with Home Assistant. • Create the necessary automations/intents inside Home Assistant so each of the three assistants recognises the devices and exposes the ON/OFF plus dimming capabilities. • Supply clean, well-commented Arduino (ESP32) code that subscribes to the chosen topics and drives ...

I have a Particle Boron and want it turned into a small proof-of-concept that watches two reed switches and a single split-core current transformer. Whenever either switch changes state or the CT reports a reading outside user-defined limits, the Boron should push an SMS straight to my phone. Please build the firmware, wire the sensors, and set up the cellular messaging so the text includes three key pieces of information whenever a condition is met: the live state of each reed switch, the measured current, and a timestamp noting when the limit was crossed. I also need your guidance in deciding the actual thresholds for both the switches and the current transformer, so factor parameter-setting into the workflow. A concise wiring diagram, commented source code ready for Device OS, and a q...

Potrzebuję funkcjonalnego prototypu niewielkiego systemu, który bezprzewodowo poinformuje o obecności osoby w pomieszczeniu. Co musi zrobić urządzenie • Czujnik ruchu PIR, zasilany wyłącznie baterią, wykrywa obecność. • Wskaźnik LED przy drzwiach – również zasilany z baterii – automatycznie zmienia kolor, gdy czujnik coś wykryje lub gdy pomieszczenie znów jest puste. • Między elementami nie może być żadnego okablowania; komunikacja ma być w pełni bezprzewodowa. Kluczowe wymagania • Bardzo niski pobór energii – zależy mi na długiej pracy na jednym komplecie baterii. • Stabilna, odporna na zakłócenia łączność (BLE, Zigbee, Sub-GHz lub inne rozwiązanie, które zaproponujesz). • Kompaktowe wymi...

I’m bringing an MLX90614 infrared temperature sensor into an ESP32-based design and need a clean, ready-to-flash solution that covers three essentials: accurate temperature readings, an immediate on-screen display, and reliable data logging. The job breaks down into two parts. First, document the wiring so I can reproduce it quickly—pin map, I²C pull-ups, and power considerations for the 3 V rail. Second, supply well-commented Arduino-compatible code (ESP-IDF is fine if you prefer) that: • polls the MLX90614 at a reasonable interval • streams both object and ambient temperatures to the Serial Monitor (or an OLED/Nextion screen if you think that’s cleaner) • stores each reading with a time stamp to SPIFFS or a micro-SD card—your call, as l...

I need robust, well-documented firmware that lets an ESP8266 on the Arduino platform both send and receive infrared commands for multiple air-conditioner remotes. Serial command-line interaction over USB or Telnet is all that’s required; no web or mobile interface is necessary. Core tasks • Build or adapt an Arduino-compatible sketch that scans incoming IR frames, decodes them, and logs the raw timing as well as the decoded protocol and data. • Implement a complementary routine that allows me to replay captured frames or craft new ones from the command line, then transmit them through an IR LED with correct carrier frequency and timing precision. • Structure the code so adding or tweaking protocols is straightforward—I will be experimenting with a variet...

I need a full EasyEDA project—schematic and routed PCB—for a tiny Atmega32U4 board that lets a computer drive a single external LED through a 3-pin XH-JST connector (GND / 5 V / LED). The board must talk and be programmable over a horizontal USB-C port and should remain as small as practical without sacrificing good layout practice. Core requirements • EasyEDA schematic using the Atmega32U4, including crystal or resonator, USB-C E-Markers (where needed), ESD protection, boot-cap circuitry and the standard reset network. • Break-out to one XH-JST-3 plug clearly silkscreened with the GND, +5 V and LED symbols. • Primary power supplied by USB-C 5 V rail. • Firmware that gives basic functionality: detect USB power, expose the MCU as a simple USB HID to ...

I am building a proof-of-concept 2D LiDAR unit from the ground up and need a mainland-based embedded electronics engineer who can handle every step of the design and bring-up process. The goal is a compact indoor scanner that excels at obstacle detection and terrain mapping while holding tight, high-accuracy tolerances. What the work involves You will take the idea from blank sheet to working board: optical layout, high-speed signal processing, motor/galvo drive, power management, firmware, and a simple USB/TTL data interface that streams polar coordinates for fusion in my existing SLAM stack. Expect heavy use of Altium (or KiCad), STM32/ESP32 class MCUs, precise timing control in C/C++, and low-level debugging with J-Link or OpenOCD. I will handle mechanical housing once you define env...

I’m putting together a Wi-Fi light switch around the ESP32 and I need complete firmware plus a small, self-hosted web interface so the unit can sit on my network and drive a dimmable light circuit. From the browser I should be able to turn the light on/off, set brightness, schedule automatic events, and reach the page securely while away from home. Key functions • Web interface (no mobile app requirement) served directly from the ESP32 • Features enabled: Scheduling, Dimming control, Remote access over the internet/LAN • Clean, responsive HTML + CSS + JavaScript (vanilla or lightweight framework) • MQTT support or lightweight REST endpoints are welcome if it simplifies remote control, but not mandatory Deliverables 1. Well-commented ESP32 source code r...

I have an ESP32-D dev board and three unused PAA5100JE optical-flow sensors. I only need to bring one online first, confirm it streams clean motion data, then replicate the solution for the other two. What I already have • A sketch that compiles but never sees the sensor • All parts on hand, breadboarded and powered • Standard Arduino IDE installed on my end for quick testing What I need from you within the next couple of hours 1. Corrected or freshly written code that initializes the PAA5100JE, verifies it over SPI, and outputs X/Y delta values on the serial monitor at 115 200 bps. 2. A clear wiring diagram (hand-drawn is fine if neat, Fritzing/KiCad even better) that shows every pin between the ESP32-D and the sensor, including power, ground, CS, MISO, MOS...

I’m putting together a new product prototype that pairs a PAA5100JE optical-flow breakout board with an ESP32. The goal is to have the ESP32 handle Wi-Fi connectivity, pull motion data from the PAA5100JE, and give me software control of several GPIOs so I can drive LEDs and switch power to an additional sensor on command. Here’s what I need from you: • An advised pin map and any level-shifting guidance for a clean, noise-free hardware hookup. • Well-structured firmware (PlatformIO or Arduino-IDE friendly) that: – Initializes the PAA5100JE and streams its measurements at a steady rate. – Publishes those readings over Wi-Fi—MQTT, HTTP, or WebSocket is fine, as long as it’s fast to implement and stable. – Exposes simple comman...

I want an ultra-low-power driver board that can run a small E-Ink panel completely untethered. The module must expose both WiFi and Bluetooth so it can receive data from a web API or a local mobile app and refresh the screen on demand. Power autonomy is critical: in addition to a rechargeable battery the board should accept a compact solar cell and scavenge ambient 2.4 GHz energy (WiFi harvesting) to keep the system alive for months without manual charging. Core expectations • Electronics: schematic, component selection and PCB layout optimized for sub-100 µA standby, including the WiFi/BLE SoC, power-path management, solar MPPT, RF-to-DC harvester and battery protection. • Firmware: ESP-IDF/Arduino or similar code that boots, joins WiFi or BLE, pulls a JSON payload, d...

I am building a proof-of-concept that lets a Raspberry Pi follow a user’s gaze and immediately translate that data into visual output on an attached screen. At the end of the job I want to be able to look at a point on the display and watch the system draw a corresponding dot, line, or free-hand stroke in real time. What I already have • Raspberry Pi 4 with camera interface available • Freedom to choose the most suitable eye-tracking library (OpenCV, MediaPipe, PyGaze, or similar) • One HDMI monitor for testing, though the code should remain display-agnostic so I can later swap in a touchscreen or e-Ink panel without major refactoring. What I need from you • Set up and calibrate the camera-based eye tracker on the Pi • Translate raw gaze coordinat...
