A schematic diagram is a simple drawing that shows how electronic components are connected in a circuit using symbols instead of real pictures.

It does not show how the circuit looks physically.
It shows how electricity flows and how components are connected.

Think of it like a map for electronics 🗺️.

Why Do We Use Schematic Diagrams?

When building robots or Arduino projects at Wayo Labs Junior, we use schematic diagrams because:

• They are easy to understand
• They show correct connections clearly
• They help in troubleshooting mistakes
• Engineers use them worldwide 🌍
