Hi. Thanks for posting your project about a run hour timer. Please find below a summary of my proposal.
SCOPE OF THE WORK:
I can design a proof of concept with Arduino Nano, a schematic with all thru-hole parts, able to detect AC, read button, drive a LED, a buzzer/chime , and write a sketch to run a timer and fulfill your requirements.
DELIVERABLES:
- Circuit diagram (.PDF)
- Bill of parts (.XLSX) with 3 vendor codes per part
- Source code as Arduino Sketch (.INO)
PRICE:
USD 129
ETA:
2 work days
BACKGROUND:
11+ years of experience in hardware design, including:
- Circuit design and simulation (Altium Designer)
- PCB layout design, high-speed and multilayer boards
- Managing PCB manufacturing, assembly, prototyping and global shipping
- Programming in C, C++, Arduino, Python, Pytorch, NumPy
- CAD design (AutoCAD Mechanical), exporting models as STEP, STL, DWG and other formats for 3D printers, injection molds or vacuum casting
Please check my portfolio with examples of past jobs. Hoping it will meet your requirements.
Looking forward to helping you with this project.
