Microcontroller Programming (STM32 / ESP32) Jobs

AI-Controlled XYZ Writing Plotter + Camera System Project Goal I am looking for a developer to build a reliable, plug-and-play system that allows an AI/LLM running on a Windows PC to control an XYZ writing/drawing plotter and view a tablet through a camera. The goal is for the plotter to use a capacitive stylus to physically interact with a tablet touchscreen. The system should be capable of: Tapping specific locations Swiping Selecting buttons/icons Typing using an on-screen keyboard The intended workflow is: User Command → AI/LLM → Camera Observation → Plotter Action → Camera Verification I should be able to give the AI a normal-language command. The AI should interpret the command, view the tablet, determine the necessary actions, physically perform those acti...

ESP32 Robot Arm + Camera with AI Integration Project Type: Fixed Price Development Budget: $1,500–$2,500 USD Target Timeline: 3–6 weeks after receiving hardware Project Overview I am looking for an experienced ESP32/robotics developer to build a plug-and-play control system connecting: Pre-assembled Hiwonder XArm 1S robotic arm Seeed Studio ESP32-S3 Sense camera Windows 10/11 PC AI/LLM running on the PC The basic architecture is: User Instruction → AI/LLM → Windows PC Server/API → Robot Arm + Camera The AI should be able to receive natural-language instructions, request camera snapshots, analyze images, issue commands to the robot, and receive status/feedback. The intended workflow is: Observe → Decide → Act → Verify → Repeat The goa...

Potrzebuję funkcjonalnego prototypu niewielkiego systemu, który bezprzewodowo poinformuje o obecności osoby w pomieszczeniu. Co musi zrobić urządzenie • Czujnik ruchu PIR, zasilany wyłącznie baterią, wykrywa obecność. • Wskaźnik LED przy drzwiach – również zasilany z baterii – automatycznie zmienia kolor, gdy czujnik coś wykryje lub gdy pomieszczenie znów jest puste. • Między elementami nie może być żadnego okablowania; komunikacja ma być w pełni bezprzewodowa. Kluczowe wymagania • Bardzo niski pobór energii – zależy mi na długiej pracy na jednym komplecie baterii. • Stabilna, odporna na zakłócenia łączność (BLE, Zigbee, Sub-GHz lub inne rozwiązanie, które zaproponujesz). • Kompaktowe wymi...

I’m bringing an MLX90614 infrared temperature sensor into an ESP32-based design and need a clean, ready-to-flash solution that covers three essentials: accurate temperature readings, an immediate on-screen display, and reliable data logging. The job breaks down into two parts. First, document the wiring so I can reproduce it quickly—pin map, I²C pull-ups, and power considerations for the 3 V rail. Second, supply well-commented Arduino-compatible code (ESP-IDF is fine if you prefer) that: • polls the MLX90614 at a reasonable interval • streams both object and ambient temperatures to the Serial Monitor (or an OLED/Nextion screen if you think that’s cleaner) • stores each reading with a time stamp to SPIFFS or a micro-SD card—your call, as l...
