Electronics fundamentals β power, breadboard, and prototyping
Robotics workbook β outlines, parts, tools, wiring, and control next to the video.
Core ideas
- Voltage pushes current through a circuit; current heats wires and devices β size conductors and fuses.
- Ohmβs law (V = IΒ·R) estimates drop across resistors and limits.
- Regulators step voltage down efficiently (LDO vs switching) β respect heat and max current.
Breadboard prototyping
- Power rails often run lengthwise; center gap isolates the two sides.
- Keep leads short; add decoupling capacitors near ICs per datasheet.
