Descripción de la oferta
I’m building a new IoT device around an Arduino-class microcontroller and need an embedded-systems specialist to move the design from concept to a field-ready prototype. Your main focus will be the firmware, but I’ll lean on you for guidance on hardware choices, pin mapping, and power-management strategies to keep the unit small, efficient, and reliable. What I already have • A high-level feature list, basic block diagram, and a shortlist of sensors and connectivity modules (BLE + Wi-Fi). • Early breadboard tests confirming that the core functionality works in isolation. What I need from you 1. Production-quality, well-commented Arduino firmware that: – Reads multiple sensors with debouncing and error handling. – Pushes data securely to a REST/MQTT endpoint. – Supports OTA updates and low-power sleep cycles. 2. Schematic and recommended parts list (KiCad or Eagle preferred) that matches the code exactly. 3. A brief test plan so I can replicate your bench tests and confirm performance on my side. 4. Clear hand-off: compile instructions, pin map, and any custom library modifications. Acceptance criteria • The code compiles with the latest Arduino IDE toolchain and runs on an ESP32-based board without modifications. • Average current draw during normal duty cycle is ≤ 50 mA. • Sensor readings arrive in my cloud dashboard inside 2 seconds of acquisition with > 98 % reliability over 24 h. If this sounds like your kind of project, let’s talk timelines and milestones so we can get the first prototype in hand quickly.
