...fine, sockets stay open, but the data simply isn’t syncing. I need a fresh set of eyes to jump on a live remote session (AnyDesk or similar) and trace the problem with me in real time. Your task is to pinpoint the break in the upload flow, adjust the code or headers as needed, and prove the fix by successfully writing and reading back a sample .txt file from R2. Key points • Hardware: ESP32 (Arduino framework; can switch to ESP-IDF if you prefer) • Storage target: Cloudflare R2, S3-compatible API • Data type in scope: plain text files only—no sensor streams or images right now • Issue observed: data not syncing even though connection/auth look good Deliverables 1.

I need a clean, well-commented Arduino sketch for the Pololu 3pi that lets the robot visit six preset locations, interact with the magnet at each spot, and return to its starting line in under four minutes. The only sensing method available is a magnetic sensor array, so all point detection and interaction logic must rely on that hardware. Two run modes have to coexist in the same program and be switchable through a simple flag, jumper, or serial command: • Intermediate – the robot must physically touch the magnet before leaving the point. • Difficult – the robot should recognise the magnetic field, stop just short of contact, and then continue. Between locations, I expect a mix of straight dashes and graceful curves; please handle path planning so th...

...interactions at the center of the experience. The project already has a solid concept, but I now need the scene brought to life with responsive touch/gesture input through AR Foundation and polished 3D assets. Unity 3D (URP) will drive the core app, while MediaPipe or OpenCV will handle hand-tracking and gesture recognition. On the hardware side the code must remain portable to Raspberry Pi OS and Arduino-based prototypes, so a clean Python or Node.js bridge is essential. Here’s what I’d like you to deliver: • A Unity scene that compiles on Android and iOS, wired for AR Foundation with robust user interaction logic (tap, pinch, swipe, custom gestures). • Integration of MediaPipe/OpenCV scripts so gestures trigger in-app events with minimal latency. &bu...

...small “suiveur solaire” that pivots a solar panel like a robotic arm. The build is Arduino-based and must deliver three key capabilities: • Object manipulation • Precise movements • Automated tasks Here’s the vision: two or more servos (or stepper motors if you prefer) will drive an articulated arm that keeps a mini-panel pointed at the sun throughout the day. When the panel is not in use, the same arm should be able to pick up lightweight test objects so I can demonstrate its dexterity. Everything has to run autonomously once powered, with calibration routines and a simple override through the serial monitor or an attached push-button interface. What I need from you – Complete, well-commented Arduino sketch written in C/C++ ...

...Total revenue figure. A lightweight call to the REST Admin API (or GraphQL if you prefer) is enough. I will supply the private-app credentials. • Destination – Hardware counter: It connects over Wi-Fi. You can target it with plain HTTP, WebSocket, or MQTT; whichever is simplest to flash onto a common ESP8266/ESP32 controller. I can handle the flashing if you give me the compiled binary or the Arduino/PlatformIO project. • Service layer: A Python, Node.js, or similar script that polls Shopify at a reasonable interval, parses the JSON response, and publishes the updated number to the device. The script should start on boot, survive network drops, and require minimal configuration (API key, store URL, device IP/topic, refresh interval). Deliverables 1. Source co...

I’m building a small bionic butterfly that “flips” in mid-air, powered by an ESP32-S3 Super Mini. What I still need is the full control system: firmware for the board plus a cross-platform mobile app that drives two micro-servos through a joystick interface. Here’s the flow I’m picturing: • The ESP32-S3 runs custom firmware (Arduino IDE or ESP-IDF—whichever you prefer) advertising itself over BLE. • The mobile app—working on both Android and iOS—connects, shows a virtual joystick, and streams position data in real time. • The board translates that data into precise PWM signals so each servo can beat the wings smoothly and synchronously. I will supply the hardware (ESP32-S3 Super Mini and servos) for your testing...

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.

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...

...learners to voice ideas, encourage emerging leaders to delegate effectively and challenge every team to debug issues together before asking for help. • Debrief at session’s end, helping students reflect on what worked, what didn’t and how they collaborated. You should feel comfortable managing 20–25 enthusiastic learners, mediating team disputes on the fly, and adapting activities when hardware (Arduino, micro:bit or similar kits) misbehaves. A collaborative mindset is critical—our instructor group plans each session collectively and swaps roles mid-stream when necessary. If you excel at turning technical tasks into opportunities for communication, leadership and creative problem-solving, I’d love to hear how you would approach 1 day roboti...

I’m building an industrial-grade control panel that runs entirely on an Arduino and drives motors through fully programmed sequences—no manual switches or computer dashboards, just reliable, repeatable automation once the sketch is flashed. Here’s what I need: • An Arduino sketch that steps each motor through the required sequence, including start-up delays, speed changes, direction (when applicable), and safe shut-down logic. • A wiring diagram that shows every connection from the Arduino pins to motor drivers, relays, fuses, and any protection or feedback components you feel are essential for industrial duty. • Parts list with exact component ratings so I can source hardware that withstands continuous operation. • Bri...

Three infrared (IR) sensors are used for line detection and path following. Sensor inputs, control logic, and actuator commands are implemented and visualised within a Simulink model running in real time on an Arduino-based platform. The leader cart operates at a manually set speed, adjusted using a physical input such as a potentiometer or control knob. Directional control is achieved by varying the relative speeds of the two rear-mounted continuous servos. The leader cart’s control logic is implemented in Simulink, allowing direct modification and tuning of control parameters. The follow...

Beyond the motor itself, factor in everything a working prototype will need: power supply, motor driver, wiring, protection devices, couplings, mounting hardware, and—if electronic control becomes necessary—an MCU or simple relay logic. Feel free to recommend Arduino, Raspberry Pi or any other control hardware only if it truly adds value; otherwise, keep the design as lean as possible. Deliverables I need from you • Complete bill of materials with part numbers, vendors, and estimated costs • Engineering calculations showing how the chosen motor RPM meets the load-rotation requirement (include torque and duty-cycle assum...

I have an Arduino Opta PLC that must act as the Modbus RTU master for two drives—a Siemens SINAMICS V20 and a Power Electronics VFD.

I want to collapse the calibration window from minutes to seconds while tightening unit-to-unit consistency and, ultimately, moving toward a batch-level or fully automated station. You’ll start by reviewing the existing schematic, BOM, and firmware repo (Arduino IDE/C/ESP-IDF).
