Arduino Jobs

I have a complete schematic ready and now need a seasoned PCB designer to translate it into a production-ready board. Your role is to create a clean, reliable layout that meets standard DFM and DFT guidelines and can be sent straight to fabrication without surprises. I’ll provide the schematic, component list, mechanical constraints, and any stack-up or impedance notes once we begin. You’ll refine placement, route signals, verify clearances, run ERC/DRC checks, and prepare the full manufacturing package. If you work in Altium that’s ideal, but KiCad or Eagle files are perfectly acceptable as long as the output files are industry standard. Deliverables: • Native design files • Gerber, drill, and IPC-356 netlist • Pick-and-place and BOM with footprints...

I have a CAN-based hardware concept for trucks and excavators that still needs an expert eye and solid firmware. The board carries a CAN transceiver plus an as-yet-undecided microcontroller; your first job will be to review the schematic and component choices, making sure the design can reliably tap into a heavy-vehicle J1939 network. Once the electronics check out, I need production-ready code that listens for multiple PGNs, performs light, on-board processing, and then forwards all remaining data to my back-end through a Bluetooth link. On the edge we have to handle three record types: sensor readings, diagnostic trouble codes, and operational parameters. Any PGN we do not actively process must be packed efficiently and shipped over Bluetooth for cloud processing, so memory management a...

I’m advancing a connected-pen prototype built around an ESP32, a compact LCD, and a 9-axis IMU. My rough Arduino-IDE sketch runs, but it needs clean, documented code and solid debugging so the three boards talk flawlessly. Key tasks include: • Writing/optimising firmware that reads IMU data over I²C (or SPI if cleaner), processes orientation, then updates the LCD in real time without flicker. • Adding power-saving routines and OTA update support for the ESP32. • Tracing and curing the intermittent reset bug I’m seeing when the screen backlight spikes. On the mechanical side, the pen’s housing is partly modelled in Fusion 360. I’d like help tightening the design and then generating reliable three-axis toolpaths for my small GRBL-based ro...

I need a schematic completed in EasyEDA for a small PCB that will trigger three illuminated or non illuminated switches. Each switch is to plug in to a JST plug. The board turns three analog inputs into a plug-and-play USB joystick (X, Y, Z) that every modern Windows, macOS or Linux PC will recognise instantly. In addition I require 2x3 male header pins that will allow 3 LED's to light up when the switch is turned on. Connection to PC The PCB is to have a standard mini USB type B connector for connection to PC or Mac. No drivers are required. Plug it in and use straight away. Powered by USB bus (+5V - 500mA) so no external power supply would be required Full-speed 12Mb USB connection. Unique serial number that helps Windows remember each device - Controller retains settings even i...

I’m building a small module that sits on a vehicle’s CAN bus, intercepts the speed signal reported in kilometres per hour, and outputs an equivalent message in miles per hour. To complete it I need an automotive electrical-systems specialist who can take the idea from schematic through to verified firmware. Here is what I’m expecting: • Hardware design – a compact, robust converter that can be wired in line with the existing CAN bus loom, powered from the vehicle supply, and tolerant of automotive noise and temperature ranges. • Software programming – firmware that listens for the specific speed PID, converts the value from km/h to mph with the correct resolution, and re-injects the new frame on the bus without disturbing other traffic. I&rsqu...

My SMK25 MIDI controller refuses to speak to my Windows PC inside Cakewalk, even though the keyboard powers on and appears to be sending data. I’m looking for step-by-step help to isolate and resolve the connectivity issue so the SMK25 is recognised as an active MIDI input in Cakewalk by BandLab. Scope of work • Diagnose why the SMK25 is not showing up (or drops out) in Windows Device Manager and in Cakewalk’s MIDI devices list • Apply or replace the correct USB-MIDI driver if needed and confirm the keyboard stays enumerated after a reboot • Walk me through any firmware, port, or cable checks that might block communication • Verify final operation by recording a short MIDI clip in Cakewalk with no latency or stuck notes I can share my screen over Zoo...

I am refining the mapping and localisation stack on a mobile robot and need an engineer who lives and breathes SLAM. The sensor mix is still open—camera-only, RGB-D, or a lidar-centric approach could all work—so part of your first task will be to advise on the optimal sensing strategy for real-time, drift-free operation. You will then design or adapt the SLAM pipeline, implement it in C++/Python (ROS2 friendly), and make sure it integrates cleanly with my existing navigation software. Low-latency loop-closure, map optimisation, and robust relocalisation in feature-poor areas are non-negotiable. Once things are running, I expect measurable frame-to-frame accuracy improvements and a clear performance report that includes CPU/GPU utilisation and update rates. Deliverables ...

I have a nearly finished, high-fidelity digital twin of an autonomous sorting line that still needs a senior Automation / Mechatronics touch before it can be signed off for commissioning. The core bridge between the KUKA KR 180 R3500 ultra, our multi-stage conveyors and all proximity sensors is already built and running; kinematics, basic I/O mapping and initial motion programs are proven in simulation. What remains is the polish and performance work: • Optimise the existing PLC-level logic and motion sequences for smoother throughput and cycle-time reduction. • Integrate a handful of new field devices (additional sensors and a diverter gate) into both the real PLC and the twin. • Finalise sensor integration, conveyor synchronisation and precise robot path planning so that...

I aim to develop a solution that will facilitate data communication between an Arduino UNO and a SIM7600E using AT+COMMAND. The primary data in focus will be temperature sensor readings.
