I only accept the price in the bud so don't come asking my budget in inbox or increasing again I'll cancel you immediately. I need a fully-commented Arduino Nano v3 sketch that handles auto-scanning on the mm238rw 5.8 GHz 8-channel video receiver module (datasheet linked above). At power-up the Nano should cycle through all eight channels until a valid video signal is found, then lock on that channel and stop scanning. A compact LED screen mounted on the front panel must show a clear “searching” indication while sweeping and switch to “signal found” (with current channel number) once video is detected. Pressing a panel button should immediately restart the scan so I can keep looking for new FPV drone feeds. Because the Nano’s only task is to driv...

I'm developing an industrial control system using microcontrollers. The system will incorporate relays, actuators, sensors, and a laser sensor.

I would like a clock, run by a Stepper motor, to rotate once per hour. The motor must be strong enough to rotate a chain that weighs about 1kg, something like a nema 17. It can be controlled by Arduino or whatever means necessary. The device must only have one power source 5v or 12v dc or 240v ac. The device must fit within a 120mm (diameter) x 30mm (height) cylinder and the motor shaft must be centred in that device. It can have more height but diameter is not negotiable. The device must be posted to me in Brisbane, Australia. I will attach it in the cylinder. it would be nice for the device to be mounted to a backing board. The device will be wall mounted like a clock and powered continuously.

I need a self-contained Python pipeline that runs on a Raspberry Pi, grabs an image from the Pi Camera, extracts any text it finds in the picture, sends that text to a lightweight AI function, then shows the AI’s short answer on a small SPI/I²C OLED display. Scope of work • Capture: Trigger the Pi Camera (libcamera or picamera2) and save a frame. • OCR: Use Tesseract, EasyOCR, or another open-source library to read text from the image. The input is always “text from images,” never scanned PDFs or live handwriting. • AI logic: Pass the recognised string to a simple question-answer routine (OpenAI API, Llama .cpp, or any efficient model you prefer) and return a concise, single-sentence reply. No lengthy explanations are needed. • Display: P...

I’m working with a Keyestudio KS4070 4-wheel Bluetooth car that my daughter assembled, but the current sketch isn’t doing what it should. With its line-tracking module, ultrasonic range sensor, and infrared receiver all wired in and verified, the car still refuses to: • stay on the black line, • swerve around any obstacle in its path, and • pause precisely at programmed checkpoints. I need a clean, well-commented Arduino sketch delivered today that makes those three behaviours rock-solid. Please structure the code into clear functions for line detection, obstacle avoidance, and stop-point handling so future tweaks are easy. Serial-print debug messages are welcome but keep them toggle-able with a macro or flag. Acceptance criteria • Upload sketch, ...

TECHNICAL REQUIREMENTS Motor Driver: - H-bridge or equivalent topology to drive a PMDC motor - Bidirectional rotation support - PWM-based speed control - Adjustable current limiting - Protection against over-current and back-EMF Proximity Sensor Feedback: - Interface with an inductive or optical proximity sensor to count motor shaft rotations - Debounce logic ...

I’m adding a green LED to my vending machine controller and need clear, no-nonsense guidance to finish the job. The LED will sit on pin 15, running at the standard 3.3 V GPIO level, and must glow steadily whenever my existing “vending _enabled” Boolean is true, switching off the instant the flag is false. I already know the resistor value, so no calculations are required there. What I need from you: • A simple wiring diagram showing pin 15, the series resistor, LED orientation, and ground return. • Confirmation that the selected pin can source the required current and, if not, the minimal code tweak or wiring change needed. • A clean, drop-in Python snippet written for either or gpiozero (your choice, just keep it concise) that exposes a function lik...

I’m building a compact, battery-powered torque meter that streams live readings to a smartphone over Bluetooth Low Energy. The job covers three tightly-linked pieces: electronic hardware, embedded firmware, and a cross-platform mobile application that works on both iOS and Android. Hardware & firmware The unit will sit between the torque sensor and the user’s phone. I need a custom PCB that conditions the sensor signal (likely through a strain-gauge amplifier), handles A/D conversion, and hosts a low-power MCU with BLE 5.x. Firmware should sample torque, apply calibration constants, then broadcast the data at a steady, low-latency rate. Power efficiency and a clean-pairing workflow are essential. Mobile application On the software side, the app should discover the met...

I’m building a new electronic digital-lock and need an enthusiastic fresher who wants real-world experience in the technical electronic domain. You’ll work alongside me on everything from early-stage circuit design to basic firmware tweaks, refining the lock’s functionality, helping validate the hardware on the bench, and documenting each step so the work can be replicated later. You do not need years of background—just a solid grasp of electronics fundamentals, the curiosity to learn fast, and the confidence to ask questions. Familiarity with simple microcontrollers, C/C++ or Arduino-style tooling, and any PCB design package will make the ramp-up smoother, but I’m happy to mentor you through unfamiliar areas. Deliverables I expect as we progress: • U...

I need a clean, ready-to-build schematic for a compact keyboard that uses an Arduino Micro as the controller. The board is for everyday, general use and will be arranged in a 3-row by 3-column matrix, with an additional key to switch between 4 modes. (10 keys in total). Hot-Swap Keyboard for the keys. Add diodes Include a 2 layer LCD Display that can be programmed on the Arduino Pro Mirco. Besides the usual character input, I want a few of those keys assigned to media functions—play, pause, volume up/down—and a couple reserved for custom macros. If you include diode placement and a clear pin map from the key matrix to the Arduino Micro’s GPIO pins, that will make firmware-writing straightforward on my side. PCB must be spaced to fit a 3d Printed enclosure Please del...

I need an engineer who can take a stock CVT Android-TV motherboard and turn it into a polished, brandable product. The job centres on building or modifying the AOSP-based firmware, flashing it on-board through UART, and validating everything on an LED panel. What I must receive from you • Custom boot logo and full start-up branding • Precise remote-control key-map that matches my IR layout • Stable Wi-Fi & Bluetooth drivers baked into the image Beyond those three deliverables, you will also handle panel timing, LVDS settings, basic app pre-loads, and general optimisation so the UI feels snappy. If OTA updating can be kept intact after your changes, that is a plus, but the core of the work is the flashable image itself. I typically work with MTK, Realtek and oth...

I need a complete hardware-to-firmware solution for a low-power, standalone temperature and humidity monitor that relies on 4G/LTE rather than Wi-Fi. The core will be an ESP32 driving a SIM7600G module, paired with a DHT22 sensor. Collected readings must be published over MQTT to my Supabase/PostgreSQL back-end. The device will sleep most of the time, wake on schedule, take a reading, push it securely, then drop back into deep sleep. It also has to recognise a lost cellular link, attempt reconnection gracefully, and log any failures for later review. Power comes from a Li-po pack, topped up through a USB-C port, so the design needs an efficient charging and protection stage. Please deliver: • Complete, readable schematic (PDF + source) • Production-ready PCB layout with G...

Firmware Adaptation for CH591 From CH592

Hi I will share the details with the shortlisted candidates. Thanks

I have an ESP32 Basic Core IoT Development Kit V2.7 installed in my truck and need firmware that will warn me whenever the Starlink router stays powered after I switch the ignition off. The sketch should watch a dedicated ignition-sense pin: while the line is high the unit does nothing special, but as soon as it goes low it must keep polling the Wi-Fi connection status in code. If the ESP32 is still associated with any network after a user configurable amount of time, an on-board LED must begin to flash, screen starts flashing and the internal speaker must chirp in tandem until the Wi-Fi link drops or the ignition is restored. I would like a simple LCD screen interface on the kit’s I²C display that shows real-time states (“Ignition ON / OFF”, “Wi-Fi CONNECT...
