Arduino Jobs

We are a hotel using a specific electronic door lock. We need to integrate these locks with our Property Management System (PMS) to automate keycard management. The lock company cannot provide an API or documentation, so we need to determine the communication protocol and build a custom interface. Scope of Work: Analyze the communication protocol between the lock system and its hardware. Develop a software middleware/API to connect our PMS to the lock system. The interface must handle core functions: creating new keycards for check-in, extending access, and revoking access at check-out. Provide clear documentation on the protocol and the solution. Test the integration to ensure it is reliable. Dumps of Master Card, Guest Cards, Configuration Cards and Add Locks Card will be provided. Th...

I have an air-quality monitor prototype on breadboard and now need a production-ready PCB. The core of the board will be an Arduino Nano, linked to Wi-Fi for cloud logging and OTA updates. Only a particulate-matter sensor has to be integrated at this stage, but I’d like the layout to leave space and headers so a future gas sensor can be dropped in without a full redesign. What I expect from you: • Complete schematic, PCB layout and clean routing for the Nano, Wi-Fi module, particulate sensor, regulated power path (USB-5 V input and Li-ion option), plus an on-board antenna or footprint. • Clearly labelled break-outs for I²C, UART and an SPI port, and pads for an optional 0.96" OLED or similar display. • All design files (KiCad or Altium), Gerbers, dr...

I’m putting together a compact desk ornament that spins on command, and I need a complete PCB solution to drive the rotation reliably.

I already have a working PCB built around an Xsens MTi-630 IMU and an NXP MKV56 microcontroller. What I need now is a technician who can revise the existing firmware so the remote camera head delivers rock-solid motion compensation on set. Your task is to design and embed a custom sensor-fusion routine that blends gyro, accelerometer, and magnetometer data from the MTi-630, then feed that fused orientation into the motor-control loop over CANopen. I’m aiming for a balanced mix of speed and accuracy so operators never feel lag yet still enjoy drift-free performance during long takes. You will be starting from my current codebase (MCUXpresso / NXP SDK), which already handles basic hardware abstraction and CANopen messaging. The focus is on: • Writing or adapting a quaterni...

I'm looking for a simple laser tag prototype using ESP32 and IR technology. This is for concept testing, not a final product. Essential features: - Scorekeeping - Player detection - Team identification Additional feedback mechanisms would be a plus but are not mandatory. Ideal skills and experience: - Experience with ESP32 and IR communication - Background in game mechanics for scorekeeping and player detection - Ability to develop a user-friendly prototype Please provide samples of similar work.

The goal is straightforward: as soon as an ESP device is present—whether connected over Wi-Fi or broadcasting in monitor mode could be spotted in hidden places

I want to turn my stock WowWee MiP into a fully-independent companion with far more capability than the original phone-controlled toy. The big push is to give it functional robotic arms—servo-driven, proportional, and strong enough to perform simple pick-and-place demos—while keeping the self-balancing chassis intact. To drive everything, I need an internal “brain” (Raspberry Pi, ESP32, or another MCU you’re comfortable with) that can: • run onboard code without any phone connection • store multiple programs in flash so I can swap behaviors on the fly • process a forward-facing camera for navigation and object tracking • handle voice-command triggers and speak back in character using a small speaker For interaction I’m l...

I'd like to create a schematic and PCB layout that I can use to print from a photo I have. The layout is based on an ATmega and an ESP32, along with a servo connected to the ATmega. I'd like a guide on how to create a schematic file that I can modify and use in the future, not just the photos I have.

I have a production-ready, IGBT full-bridge welding inverter that already powers both TIG and MMA processes, yet the embedded side still needs a final expert pass before release. The control board is built around 8051 and STC MCUs running Keil C51 firmware, and every line of code directly shapes arc stability, HF start, AC balance, soft-start, and safety interlocks. The short-term goal: review, tidy, and extend the existing code so it drives the power stage flawlessly in TIG and MMA, AC and DC. That means refining PWM timing, gate-drive dead-time, current-feedback filtering, and all the little state-machine details that separate a decent welder from a great one. Core tasks and deliverables • Audit the present C51 codebase, flagging race conditions or timing pitfalls. • Im...

I have a Siemens LOGO PLC on my network that speaks Modbus-TCP and I need a clean, well-commented Python script that can both read from and write to its registers using the pyModbusTCP (or compatible) library. The goal is to end up with a small module I can drop into a larger project, so clarity and reliability matter more than flashy UI. Here’s what I expect: • A single .py file that opens the connection to the LOGO (IP, port and slave ID must be easily configurable at the top of the script). • Functions I can call for typical tasks: read_coils, read_holding_registers, write_single_coil, write_single_register (or their pyModbusTCP equivalents). • An example section (under if __name__ == "__main__": ) that demonstrates the above functions in action wi...

I am assembling a pool of recently-graduated electrical engineers from Pakistan who can jump straight into hands-on circuit design, MATLAB/Simulink modelling, and clear, publication-ready report writing. Day-to-day work will range from breadboard-level prototyping to full simulation and verification, so the stronger your foundations in analogue and digital design the better. The tasks you’ll tackle typically start with a concept sketched in Proteus or Multisim, move into schematic and PCB work in Altium, and finish on the bench or in a virtual lab via LabVIEW or TinkerCAD. Microcontroller and embedded targets rotate between Arduino-based boards, Raspberry Pi modules, and mid-range FPGAs, so comfort switching among those platforms is essential. Core expectations • Design or r...

I need a seasoned PCB designer located in Pakistan who can take a concept right through to production-ready files. The boards you create must interface reliably with Arduino, Raspberry Pi, and FPGA modules, so familiarity with their pinouts, signalling levels, and power budgets is essential. You’ll start by translating my functional requirements into clear schematics, then handle the full PCB layout, component selection, and DFM checks. I expect well-organised source files plus manufacturing outputs—Gerbers, drill files, pick-and-place, and an accurate BOM—with every revision traceable. If you prefer Altium, KiCad, Eagle, or OrCAD that’s fine; just let me know which environment you’ll use so I can open the files on my end. Because these boards may evolve...

I already have the hardware in hand (see the exact unit here: ) and need it configured into a rock-solid link for a DJI Matrice 400. The goals are simple but non-negotiable: • The device must pair over Bluetooth with smartphones and tablets, then feed telemetry and video to the Matrice in real time. • The whole chain has to stay online even when nearby frequency jammers or other RF noise are present. • Live status dashboards and alerts are required so I can see, at a glance, that every hop in the link is healthy. Here’s how I picture the collaboration: 1. You review the hardware specs and choose the most resilient protocol settings (frequency-hopping, spread-spectrum, encryption, power levels, antenna layout, etc.). 2. You walk me through the exact configurati...

I am ready to move fast on a custom sonar project built around STM32 hardware (CubeIDE + HAL). Your task is to create production-grade firmware that: • Captures long-range sonar returns through the onboard ADC and a TUSS4470 (or comparable) front-end, with signal conditioning tuned for maximum range performance. • Streams that data in real time using a compact, binary UDP protocol—both transmit and receive paths—so it plays nicely with an existing mobile-app protocol. • Listens for run-time commands such as gain adjustments, start/stop, mode selection, and ping-rate changes, then acts on them immediately. Deliverables I need: 1. Well-documented STM32 firmware source code. 2. A clear protocol reference (frame layout, timing, byte ordering, command set). ...

I am rolling out a trio of inter-linked prototypes that tackle pressing urban and environmental challenges while showcasing cutting-edge AI, blockchain, and IoT engineering. First, the AI-driven Smart Traffic System must ingest multi-sensor feeds, apply real-time reinforcement learning, and demonstrate measurable gains in a simulation such as SUMO—specifically a double-digit reduction in congestion and wait times across a 20-intersection grid. Second, the Blockchain Voting System needs an end-to-end verifiable ballot flow. I expect audited Solidity or Substrate contracts, mobile-friendly front-end, zero-knowledge vote secrecy, and a testnet demo with at least fifty dummy voters that passes a public audit script. Third, the Solar-Powered Smart Watering System will run on a low-powe...
