I will design your electronic circuit and wiring diagram

A clear schematic before you build saves you the parts you'd otherwise buy

twice.

I'm an electrical and electronics engineer. I'll design your circuit, draw a

schematic you can build from, and specify the components with real part

numbers and links.

WHAT I COVER

Sensor and microcontroller interfacing. Relay, motor and driver circuits.

Power supply and battery selection with a proper power budget. Level shifting,

pull-ups, protection and decoupling the details that decide whether a

prototype survives.

WHAT YOU GET

A clean schematic. A component list with part numbers and suppliers. A power

budget showing current draw. Notes on what to watch out for when you build it.

WHAT I DON'T DO

Mains-voltage design, safety-critical or medical circuits, and high-speed or

RF work. Those need someone who does them daily, and I'd rather point you to

one than learn on your project.
