I’m building an educational, IoT-enabled play mat designed especially for children aged three to five. When a child steps, taps or sits on different zones, I want the mat to recognise the interaction and trigger playful learning responses—lights, sounds or messages sent to a companion mobile app. Here’s what I need from you: • Hardware logic so each zone on the mat can reliably detect pressure or touch and send that data wirelessly. • Firmware that converts those raw sensor readings into tidy, low-latency events the app can understand. • Simple proof-of-concept software (mobile or web) that shows the events, plays a sound or displays a visual so I can demo the core learning activities. I’m open on the exact platform; ESP32, Raspberry Pi Pico W ...

Print the measured values continuously to the Arduino Serial Monitor...

I want to build a small, self-contained charging station that wakes up only when it “sees” a bottle and a can. The core will be an Arduino (any recent 32-bit board is fine) tied to a solar panel and battery pack. A lightweight AI vision module or camera running something like TensorFlow Lite or OpenCV should continuously—or on a duty-cycled basis—look for bottles. The moment a bottle is detected, the system must move straight into the charging routine without waiting for external confirmation; no alerts, no logging, just automatic activation. What I need from you • Complete Arduino firmware that integrates the vision trigger with the charge-controller logic. • A schematic / wiring diagram showing how the camera, solar panel, charge controller, and any...

I have an ESP32 dev board on my bench and need it turned into a compact sensor hub. The entire focus is sensor integration—specifically motion & proximity plus light & sound. Some of the devices will be hard-wired to GPIO pins while others should connect wirelessly, so the firmware must handle both connection paths seamlessly. Here’s exactly what I need delivered: • Well-commented source code (Arduino-ESP32 or ESP-IDF) that polls each sensor, filters noise, and publishes readings over Serial and MQTT. • A clear wiring / pin-out diagram for the hard-wired sensors. • Configuration notes that let me pair or re-pair any wireless sensor modules. • A short README covering library installs, flash commands, and expected output. Acceptance criteri...

I’m putting together a very small-scale project on an Arduino Uno and simply need a clean, well-commented sketch that switches an LED on and off. No elaborate libraries or peripherals—just straightforward LED control that compiles in the current Arduino IDE and can be uploaded over the standard USB cable. What I expect from you • An .ino file that drives either the onboard LED (pin 13) or an external LED on any digital pin I can redefine at the top of the sketch. • Clear inline comments explaining each step so a beginner can follow the logic and reuse the code in future experiments. • A short read-me noting the exact IDE version you compiled with and the wiring diagram if you choose an external LED. That’s all—simple, reliable, and ready to ru...

I’m developing a compact data-acquisition module and need a local electronics engineer in Austin who can take the mixed-signal front-end from concept to ready-to-fab documentation. The heart of the job is a clean, low-noise analog section feeding a high-resolution ADC, with the digital side handling basic buffering and a simple SPI or I²C hand-off to my existing microcontroller board. We’ll meet in person for the initial requirements review and again when hardware is on the bench so rapid tweaks are possible. I already have rough performance targets—sampling at 1Hz, 12–16-bit resolution, and a 12V single-rail supply—but I’m looking for your guidance on component selection, input protection, and clocking strategy to hit those numbers without over-en...

I want a simple two-channel radio link that can do just two things reliably: 1) vary the speed of my brushless DC motor through its ESC (accepts S-Bus or standard PWM) and 2) toggle a single relay on or off. Hardware • I already have the motor, ESC, and relays. • You may choose Arduino, Raspberry Pi, or any Adafruit board—use whichever keeps the build small, inexpensive, and stable. Radio requirements • The handheld transmitter must let me select the operating band with a physical switch: 2.4 GHz, 900 MHz, or 433 MHz. • If LoRa is the cleanest way to hit those bands, great—just make sure the LoRa hop gives me at least a 1 000 ft (≈300 m) clear-line range. Long-range reliability is more important than data rate or extreme power savings...

I’m building a research-grade quantum simulator in Python and need a robust codebase that can accurately model multi-qubit circuits, apply standard gate operations, and return state-vector or density-matrix outputs. Whether you prefer to work directly with NumPy/SciPy or leverage existing open-source frameworks such as Qiskit, Cirq, or QuTiP is completely up to you; the key requirement is clean, well-documented code that runs reliably under Python 3.11. Please provide: • A modular simulation engine capable of handling at least 10-15 qubits, with optional noise or decoherence modelling • A clear, Pythonic API for defining circuits, executing simulations, and extracting results (probabilities, expectation values, etc.) • Unit tests plus a concise README that cover...

What this lets you verify The sensor is mainly used to confirm that the system works correctly. Verify balloon inflation Pressure should rise when the actuator compresses the ...

I want to put an end to guessing when my plants need water by building a small, battery-friendly device that measures soil moisture, pushes the reading to the cloud, and emails me whenever the level drops below a threshold I can set in a companion mobile app. Core features • Soil moisture detection with reliable, calibrated readings • Wi-Fi or BLE link from the probe to the cloud • Email alert generation (no SMS or push needed) • Mobile-only dashboard that shows current moisture %, historical trend, last alert time, and a slider to adjust the alert threshold I’m open to an ESP32, ESP8266, or similarly low-power MCU and prefer code in Arduino/C++ or MicroPython if that speeds things up. Low standby current, deep-sleep cycles, and a compact PCB (or even a ...

I am building a small Windows 10 service that will sit between an IEC 61850 IED and downstream Modbus-TCP clients. The gateway must act as an MMS client, pull a defined set of Logical Nodes (both status and analog), then expose each value as a Holding Register on a Modbus-TCP server that can listen on any user-selectable port. Key details you should know • The Windows PC runs Python 3.9. • The IED is reachable over a direct Ethernet connection—no serial converters or intermediate devices. • All data mapping must come from the device’s ICD/SCL file, so parsing that file correctly is critical. • The program has to auto-start with the OS and run continuously (24/7) without manual intervention. I expect you to lean on libiec61850 for the MMS side and...

I need a working prototype of a compact pool-cleaning robot designed, built, and shipped to Pune by 20 March. Its two core tasks are debris collection across the pool floor and reliable wall-climbing so it can scrub and vacuum vertical surfaces as well. The unit must run on a rechargeable battery pack—no cords in the water—and be steered with a simple handheld RF remote (forward, reverse, left, right, start/stop). A smartphone app or timer isn’t necessary; keeping the hardware lean is key because the entire build, plus packing and freight, must stay within an 18 k INR ceiling. I’m open to clever use of 3-D printed housings, sealed brushed or BLDC thrusters, and readily available filters to hit that cost target while ensuring waterproof integrity. Good buoyancy cont...

I’m building out the engineering team for our AI-driven startup and I need a dedicated embedded developer who can take full ownership of the automotive side of our product line. Your day-to-day work will revolve around three core responsibilities: writing robust firmware that brings our AI features to life, integrating that code seamlessly with sensors and control units already in the vehicle stack, and collaborating on hardware design decisions so everything works together flawlessly. We are moving fast, so I’m looking for someone who is comfortable working full-time alongside our in-house data science and mechanical teams, iterating quickly from prototype through to production-ready boards. Expect a hands-on role that blends coding, debugging on target hardware, and validati...

I have a small STM32-based prototype that needs a tidy firmware layer to read a digital sensor running off the 3.3 V rail and perform on-board data processing. The task is focused purely on sensor data acquisition and manipulation—no motor control or external comms stacks are required beyond whatever interface the sensor ultimately uses. Scope • Bring-up of the chosen digital interface (we will settle on the exact line once we start). • Continuous sampling with lightweight processing: basic filtering/averaging and a simple validity check. • A clean API or callback so the main application can fetch the processed values. • Well-commented C code in a CubeIDE or bare-Makefile project plus a short README explaining pin assignments, clock config, and how to rep...
