I’m building a new electronic digital-lock and need an enthusiastic fresher who wants real-world experience in the technical electronic domain. You’ll work alongside me on everything from early-stage circuit design to basic firmware tweaks, refining the lock’s functionality, helping validate the hardware on the bench, and documenting each step so the work can be replicated later. You do not need years of background—just a solid grasp of electronics fundamentals, the curiosity to learn fast, and the confidence to ask questions. Familiarity with simple microcontrollers, C/C++ or Arduino-style tooling, and any PCB design package will make the ramp-up smoother, but I’m happy to mentor you through unfamiliar areas. Deliverables I expect as we progress: • Updated schematics for each design revision • Clean, well-commented firmware source files with version control commits • A short test report summarising bench results for every milestone If you’re ready to turn classroom knowledge into a working digital-lock product, let’s get started.
