Electronics & Circuit Prototyping

Turning a schematic into a breadboard (or a first PCB) is how embedded work becomes real. This subject is about wiring a supply, a microcontroller, and a few peripherals so the circuit is electrically sane: polarity, current paths, pull-ups, and not feeding 5 V into a 3.3 V pin. Theory lives in Electronics fundamentals; here you build and check.

Starting Points

  • Electronics fundamentals
  • Horowitz, P., & Hill, W. The Art of Electronics (selected chapters on DC circuits).
  • Platt, C. Make: Electronics. Maker Media.

Key Points

  • You draw a simple schematic (supply, MCU, one sensor or actuator, GND) before you wire it.
  • You prototype the circuit on a breadboard or protoboard with correct polarity, decoupling, and current-limiting where needed.
  • You choose and place pull-ups/pull-downs and level shifting when voltages differ.
  • You verify voltages and continuity with a meter before you apply power to a new wiring change.
  • You document the circuit (photo or schematic) so a teammate can reproduce it.
