Arduino Jobs

I have a custom board built around the STM32G031 and I want a clean, production-ready firmware project created in C with STM32CubeIDE. Your first task is to bring the microcontroller to life: set up the system clock, configure the required GPIO pins, verify the build, and program the device. Here is the scope I need covered: • Create a CubeIDE project that targets STM32G031, using either HAL or direct LL drivers where it makes sense. • Configure clock tree (HSE, HSI or internal PLL as required) so the MCU runs at the specified operating frequency. • Initialise all GPIOs I mark on the schematic; direction, speed and pull settings must match the hardware design. • Build, generate the .hex/.bin files and flash them onto the board through ST-Link over SWD. • ...

Project Title: FPGA-Based Real-Time PCB Defect Detection and Localization Project Description: I am looking for an experienced freelancer to assist with the development of my ECE final-year major project, titled “FPGA-Based Real-Time PCB Defect Detection and Localization.” The objective is to develop an FPGA-based system that detects and identifies the locations of visible defects on printed circuit boards (PCBs). The proposed system should compare a reference PCB image with a test PCB image and use image-processing techniques to detect differences that indicate potential defects. Required Features: 1. PCB image acquisition or loading of sample PCB images. 2. Image preprocessing, including grayscale conversion and thresholding where appropriate. 3. Reference and test image...

I need an audio-based AI that takes plain text and returns a natural-sounding English voice output. The end goal is a production-ready text-to-speech (TTS) engine I can integrate into web and mobile apps. Here is what I expect as the finished work: • A trained TTS model (neural or parametric) optimised for clear, human-like English speech • An inference script or lightweight API endpoint (Python/Flask or Node preferred) that accepts text and streams back audio (MP3 or WAV) in real time • Simple usage documentation plus a quick demo project showing how to call the service Acceptance criteria • Latency under two seconds for a 200-character string on a standard GPU instance • No noticeable robotic artefacts at common sampling rates (22 kHz or higher) &bu...

need a small IoT device built that can read data from a Selec 500 UCI PID controller through its RS-485 Modbus port and send those values automatically to a Google Sheet via Wi-Fi. The device should: 1. Use an ESP32 board (low-cost, Arduino-compatible). 2. Take input from the RS-485 port of the Selec PID using a MAX485 module. 3. Host a Wi-Fi setup page (so user can enter SSID & password). 4. Send the PID readings (PV, SP, and OP values) every few seconds to a Google Sheet (via a Google Apps Script endpoint). 5. Work on 5V DC or USB power. 6. Be housed in a small project box or DIN rail enclosure for industrial use.

Chcę ożywić mój ekran Waveshare, wyświetlając na nim własną animację. Posiadam gotowy plik GIF, lecz wymaga on konwersji do formatu obsługiwanego przez Arduino. Mogę dostarczyć grafikę także jako JPEG lub PNG. Twoje zadanie: • Przekonwertuj mój GIF (lub wersję JPEG/PNG) do formatu akceptowanego przez bibliotekę. • Napisz przejrzysty, dobrze skomentowany szkic Arduino, który odtwarza animację na ekranie Waveshare. Kod powinien działać na standardowym środowisku Arduino IDE i korzystać z dostępnej biblioteki.

Custom 3-PIR GSM Anti-Theft Security Alarm with SMS, Call & Relay PROJECT DESCRIPTION: I am looking for an experienced embedded hardware and firmware developer to design and develop a custom human motion / anti-theft security alarm using an ATmega328P (Arduino-compatible) microcontroller. The device will use 3 external PIR motion sensors connected to the main PCB through long cables. The main feature is a selectable PIR detection threshold of 1, 2, or 3 sensors. This will help reduce false alarms. MAIN PIR LOGIC: The device has: * PIR 1 * PIR 2 * PIR 3 The user can select the required number of PIR sensors that must detect movement. Threshold 1: Any one PIR becomes active = intrusion confirmed. Threshold 2: Any two PIRs become active = intrusion confirmed. PIR1+PIR2, PIR1+PIR3...
