Arduino Jobs

I need a simple, single-board PCB layout created from an already completed and fully tested Fritzing (.fzz) project. The circuit logic, components, and pin mappings are 100% verified on a physical breadboard. This is a very quick micro-task for an experienced electronics engineer. The design is an ultra-low-power Smart Irrigation Sensing Node using an all-3.3V power architecture. Key Specifications & Pin Mapping: • Microcontroller: Arduino Pro Mini (3.3V variant) • Radio Module: LoRa Ra-01 (Antenna area must be kept completely clear of copper traces and ground planes). Pin connections required: NSS to D10, RST to D9, DIO0 to D2, plus standard hardware SPI lines (D11, D12, D13). • Power Input: Direct 3.2V LiFePO4 Battery connection to the Arduino VCC rail (Bypassing the ...

Hi, I need a schematic and PCB design for my college project, an Automatic Soap Dispenser with Low Soap Level Detection. I am using: - Arduino Nano V3.0 (ATmega328P) - TTP223 capacitive touch sensor - XKC-Y25-V non-contact liquid-level sensor - Kamoer KPHM100-HB peristaltic pump — 12 V, 0.5 A - LED for low-soap indication - Pump driver circuit Operation: When the TTP223 is touched, the Arduino Nano should activate the 12 V peristaltic pump for a programmed amount of time and then stop it. The XKC-Y25-V will be mounted outside the soap container at the low-level point. When the soap becomes low, the Arduino should turn on an LED. The Arduino must not drive the pump directly. Please include a suitable transistor/MOSFET pump-driver circuit and flyback protection. The pump uses 12 V, ...

I’m planning a comprehensive set of advanced-level video lectures that will walk learners through deep learning techniques, natural language processing, and reinforcement learning. Every lesson must feel like a polished conference talk: clear theory explanations, live Python coding in Jupyter or a similar environment, and crisp screen-plus-voice capture with unobtrusive on-screen graphics. What I need from you • A cohesive syllabus that sequences the three focus areas logically and flags any prerequisite knowledge. • Slide decks, notebooks, datasets, and any supplementary reading you reference, all organised by module. • Studio-quality recordings—clean audio, 1080p video, readable code font, and smooth editing that blends slides, code walkthroughs, and tal...

I am developing a complete FPGA-based 5G NR Low-PHY platform for an O-RAN 7.2x radio architecture. The objective is to design, implement, integrate, optimize, and validate the complete real-time digital signal-processing chain rather than isolated FPGA blocks. The scope covers O-RAN 7.2x/eCPRI fronthaul processing, IQ compression/decompression, FFT/IFFT and cyclic-prefix processing, resource and antenna mapping, 2×2 and 4×4 MIMO, precoding and digital beamforming, DUC/DDC, channelization, interpolation/decimation, digital filtering, CFR, DPD, calibration, gain/phase correction, multi-carrier processing, timing/synchronization, and high-speed ADC/DAC interfaces. The engineer will be responsible for FPGA architecture, RTL/HLS/IP implementation, block integration, clock-domain a...

I’m developing a fully automatic device that keeps both residential and commercial rooftop solar arrays spotless by pairing a belt-driven carriage, a soft brush and a sparing water-spray line. The core objectives are clear: cut manual labour to near-zero, use as little water as practical and achieve faster, more uniform cleaning ­– all while making the unit simple enough for a single technician to clip in place during installation. Here’s what I need help with: • Complete mechanical and control-system design for the belt mechanism that can travel the length of typical rooftop strings and return to a docking station automatically. • Soft-bristle brush selection and drive layout that won’t abrade panel coatings yet removes stubborn dust. • Lo...

I need to get a clear, working understanding of how my smart sensor EPD SS3-EW is programmed when it is tied into a MACH-ProZone controller over BACnet. At the moment the interface works erratically and any change I make in RC-Studio shows up unpredictably on the sensor. I want to pinpoint the programming mistakes, learn the correct sequence for mapping objects, and leave with a repeatable method that I can apply on future jobs. The work will happen remotely: I can share the current RC-Studio project, all trend logs, and live screen-share access to the controller and sensor. You will walk me through each step, explain why the sensor is failing to respond, and illustrate the proper way to build the BACnet objects, write the logic blocks, and push updates without locking the device. Delive...

I have an ESP32-S3 board fitted with an ES8311 codec and a small speaker. During a short face-to-face session (about one to two hours) I want to: • Install and test the Arduino core, LVGL graphics library, and the ES8311 audio driver on the board. • Load a few sample audio files, then demonstrate recording through the codec and playing the captured audio back through the speaker. • Connect the board to a public or user Wi-Fi network and verify reliable internet access. We will meet somewhere around Sheikh Zayed; let me know what location works for you, your earliest available time slot, and the cost for the visit. I can be reached directly on 01228834534 to finalise details. Bring whatever tools you need (laptop with Arduino IDE, USB-to-Serial cable, etc.) and be ready...

I have a Yale electric rim lock already installed and I want to take it a step further by adding three parallel ways to open it: a keypad PIN, an RFID tag/card, and a biometric fingerprint reader. The main driver is day-to-day convenience for family and frequent visitors—no more fumbling for physical keys—so the solution has to be fast, reliable, and easy to maintain. Here’s the scope in practical terms. I need a compact control module—Arduino, ESP32, or any other microcontroller you feel best fits—wired to the Yale lock’s strike mechanism. It must read all three credentials, decide locally, then trigger the solenoid without noticeable lag. A small OLED or LED feedback indicator and a relay or MOSFET driver for the lock should be part of the circuit. Po...

I need a full-stack solution that covers both the electronics and the software behind a 10 m air-pistol / air-rifle training target. Hardware – Design, program and calibrate an Arduino or ESP32-based PCB that detects each pellet impact, timestamps it and sends the raw x/y coordinates wirelessly. – Supply the firmware, pinout diagram and any Gerber or KiCad files so I can reproduce the board locally. Software The data from the target must appear in real time on an app that runs on iOS, Android and Desktop (Windows & macOS). A single codebase (Flutter, React Native, Qt or a framework of your choice) is fine as long as all four platforms are delivered. Core features • Live shot display with 10-ring scoring for both air pistol and air rifle distances • Ma...

Ich möchte einen funktionsfähigen Prototypen einer 24-Stunden-Uhr entwickeln, die mit einem Arduino und einem Echtzeit-Modul arbeitet. Die Uhr soll drei wählbare Anzeige­modi haben, die über einen Schalter umgeschaltet werden können. Anzeige­modi 1. Priorität für den ersten Prototyp: Für jede volle Stunde leuchtet genau eine LED. 2. Invers dazu: Standardmäßig leuchten alle LEDs; zur vollen Stunde erlischt jeweils die entsprechende LED. 3. (Optional für diesen Prototyp) Aufsummieren der Stunden – z. B. 7 Uhr → LEDs 1-7 leuchten. Hardware-Vorgaben • Arduino (Uno oder vergleichbar) • Echtzeit-Modul (RTC, z. B. DS3231) • LED-Modul nach Wahl (ich bevorzuge ein vorkonfektioniertes LED-Modul,...
