I’m an electronics and communication engineering student working on a course-capstone that hinges on solid microcontroller programming. The hardware is already laid out; what I’m missing is clean, reliable firmware and a bit of mentoring so I fully understand every line that ends up on the chip. Here’s what I need from you: • Write well-structured, thoroughly commented C/C++ code for a mainstream MCU (I’m leaning toward an ARM Cortex-M such as an STM32, but I’m open to your recommendation). • Supply all project files and a concise build/flashing guide that works in either STM32CubeIDE, Keil, or PlatformIO. • Walk me through the code in one or two live review sessions, help me flash it, and iron out any bugs. Acceptance criteria: &...

I need a cohesive pack of Amazon-ready visuals for a new electronics item I’m listing on the U.S. marketplace. You’ll receive the full user manual so the copy and visuals match the product perfectly. Scope The project covers every visual touchpoint shoppers will see—from the first thumbnail to an engaging animated explainer. The main images must look crisp and proportional in hand, clearly show the packaging, and call out button functions and technical specs. Lifestyle scenes should place the device naturally in spots such as a hotel room, bathroom, car, or meeting room so buyers understand its versatility. Deliverables • 7–8 Amazon main images that mix close-up detail, lifestyle use, and concise spec callouts • A+ Content image set (modules...

I’m building a tool that can generate complete PCB layouts on its own and I want an electronics-savvy developer to help me bring the idea to life. The first release will focus exclusively on single-layer PCBs, but it has to feel polished: auto-routing must be reliable, schematic capture smooth, and real-time error checking immediate and accurate. Here’s what I need you to tackle: • Translate design rules for single-layer boards into code that my algorithm can digest. • Shape an auto-router that balances speed and trace integrity. • Wire up an intuitive schematic-capture front end (framework and language are flexible). • Embed a real-time DRC engine that warns users as they draw. If you’ve written layout algorithms, scripted PCB too...

I’m looking for a designer who can craft eye-catching Facebook promotional ads in Arabic for an electronics and gadgets online store.
