What You Will Build

By the end of this tutorial, you will power a breadboard and turn on an LED safely using only basic components from the kit.

A breadboard lets you build circuits without soldering.

• Each row of holes is electrically connected horizontally
• The long side rails are for power (Voltage and GND; the PSU includes 3V3 and 5V)
• The center gap separates the left and right halves

If two metal legs are in the same row, electricity can flow between them.

Challenge 1 : LED On/Off with Button

This project is built in Tinkercad Circuits, not on real hardware yet.

Tinkercad simulates real electronic behavior, so the habits you build here will transfer directly to a physical breadboard later.

What You Will Build

By the end of this challenge, you will have:

• A button that turns an LED on only while it is pressed
• An expanded version where one button controls multiple LEDs

You will start with a simple circuit and then extend it, not rebuild it.
