Microcontrolador Jobs

Estoy desarrollando un prototipo IoT de bajo consumo para un vertedor inteligente de bebidas y busco un ingeniero embedded/freelance con experiencia práctica en Nordic Semiconductor nRF52 y Bluetooth Low Energy. El objetivo del prototipo es detectar cada servido de una botella mediante un reed switch activado por un imán colocado en la tapita abatible del vertedor. Cada vez que el reed switch se active, el microcontrolador debe enviar automáticamente un evento BLE con un ID único del vertedor hacia un dongle nRF52840 PCA10059 conectado a una computadora, que funcionará como hub/receptor. No busco una empresa grande ni una solución sobredimensionada. Busco un especialista técnico que pueda llevar el prototipo a una prueba funcional, documen...

I need our existing laser-maze exhibit adapted before we use it so children can explore it safely It comes with class 3 lasers but we need to change these to class 2 and introduce a system that shuts the lasers down as soon as the beam is broken and then comes back on after five seconds providing the beam Is clear The system is already installed and has seven lasers on one wall and small mirrors to reflect to each beam. The maze is around 3 x 2 m

I need a working human-computer interface that can both pick up and broadcast data over Bluetooth at the highest speed the protocol allows. The data flowing through it will be full-rate cellular communications data rather than simple audio or text, so throughput and low latency are critical. On the input side the unit will read Qi energy and Acu-meridian energy via harness-style skin contacts. Those raw sensor signals have to be conditioned, digitised and pushed straight to a tablet over Bluetooth without noticeable lag. In the opposite direction the tablet will be able to transmit control or stimulation patterns back to the interface just as quickly. The job covers hardware design, embedded firmware and a basic demo app for a tablet or computer: • Hardware: schematic, PCB layout an...

Wireless Load Cell Monitoring Systems About the Role We're building out a wireless weighing and monitoring solution from the ground up, and we need a seasoned embedded engineer who can own the technical journey — from early prototype to a validated, field-ready product. This role sits at the intersection of hardware and software. You won't just be writing firmware in isolation; you'll be shaping system architecture, wiring up hardware, writing and debugging embedded code, and pushing performance across the board. At a high level, the system pulls weight data from a network of load-cell-equipped sensor nodes spread across multiple locations, processes that data on-device, pushes it over a wireless link, and surfaces it through a cloud-connected platform for remote acce...

I need a compact Bluetooth mouse engineered from the ground up with four physical buttons, a smooth scroll wheel, and a USB-C port for both charging and optional wired use. Beyond the standard right- and left-click, the two extra buttons have to ship pre-mapped to volume control (up / down or mute / un-mute) yet remain fully re-programmable through companion software or firmware so users can assign any shortcut they like later on. The build should feel as solid as today’s premium portable mice, keep latency low, and work cross-platform without separate drivers. I’m open to Nordic, Cypress, or similar Bluetooth LE chipsets as long as you hit excellent battery life and achieve seamless reconnection after wake-up. USB-C power management and over-the-air firmware update capability...

Ho 6 Raspberry CM4 che non si accendono e, dopo vari tentativi, sospetto un guasto hardware localizzato sulla scheda madre. Non vedo bruciature, crepe o altri segni evidenti, ma il dispositivo rimane completamente morto anche con alimentatore sicuramente funzionante. Cerco chi possa: eseguire la sostituzione dei componenti difettosi • verificare a banco che il Raspberry torni ad avviarsi e a collegarsi correttamente a rete e periferiche USB Preferisco una soluzione chiavi in mano: mi va bene spedire il dispositivo al laboratorio, purché sia testato prima della restituzione. Accetto anche una consulenza dettagliata se riesci a guidarmi passo-passo con gli strumenti giusti. Forniscimi tempi stimati, metodo di test finale e garanzia sul lavoro svolto.

Project Title Design a Logic Gate Based Non-Programmable Sensor-Actuator PCB — Prototype Development Project Overview I need a custom electronics board designed and prototyped around a combination of Logic Gates, built for a non-programmable, hardware-only sensor-to-actuator decision system (no microcontroller/firmware involved). The board should be robust, classroom/hobbyist-safe, and ready for small-batch prototyping. Concept The core idea is a hardware logic control board where inputs (sensors which uses only digital signal like IR sensor, PIR sensor, LDR sensor etc.) and outputs (actuators/dc motors, LED and buzzer) are combined using any gate logic — with no coding or programming required. Detailed Requirements 1. Power Requirements Power input via a 9V battery....

I need a compact, Linux-friendly suite of command-line utilities written in C or C++ that lets me run deep diagnostics on the following components: • RAM Memory • CPU • HDD & SSD (including low-level write/partition and speed tests) • RF-UNIT support where applicable The tools must be completely CLI-driven so they can slot into existing bash automation. For each utility I also need concise professional usage notes—syntax examples, expected output, and any kernel-module or package prerequisites—so a technician can get productive within minutes. Additional scope items: – Benchmark and stress-test options to reveal peak throughput and thermal throttling on RAM and CPU. – Sequential and random read/write tests on block devices, with sm...

I want to create a branded control board that keeps the familiar Arduino UNO R3 footprint yet swaps the ATmega328P for an ESP32. The finished board must: • expose the usual analog inputs, PWM outputs, serial ports and full digital I/O • break-out every pin through sturdy screw terminals instead of header pins • carry an on-board battery cradle for two 18650 cells (3.7 V each) and an integrated 2-cell BMS • arrive pre-flashed so it shows up in the Arduino IDE exactly like a normal UNO-style target Because the unit will be wall-mounted, an ABS enclosure that matches the board outline, standoffs and connector layout is part of the job. I need mechanical files (STEP/STL) alongside the electronics deliverables. Deliverables 1. Schematic, PCB layout and Gerber/ODB files 2...

I’m building the low-level firmware for an ARM Cortex-A microcontroller and need help closing the remaining gaps in startup code, peripheral configuration, and board-level testing. The toolchain is already in place (GCC, OpenOCD, and a J-Link probe), and the hardware boots, but several peripherals still need clean, maintainable drivers and the overall initialization sequence must be tightened for reliable production use. You’ll dive into: • Writing or refactoring C/C++ startup routines, linker scripts, and BSP code specific to this Cortex-A device • Bringing up UART, SPI, GPIO, and a high-speed interface that feeds data to an upstream processor • Tracing hard faults with JTAG/SWD and delivering concise root-cause notes so I can reproduce your findings &bul...

I have a microcontroller-based board that will sit in the field and quietly record temperature readings from one or more digital sensors. Your job is to write the embedded firmware that pulls those readings at set intervals, time-stamps them, and stores everything persistently in a neat, easily downloadable file (CSV or similar). Core needs • Reliable polling of the attached temperature sensors (currently using a standard one-wire digital device, but code should be abstract enough to swap to I²C if required later). • Configurable sample rate—default 1 Hz but changeable over a simple serial menu or compile-time constant. • Local, non-volatile storage on the board’s microSD slot; automatic file rollover when a maximum size is reached so nothing is eve...
