Components Required for the Project
The following components are used in this Grade 6 STEM Activity project.
| Component | Purpose |
|---|---|
| Breadboard | Platform for circuit building |
| LED | Produces light |
| Push Button | Controls ON/OFF operation |
| Resistor | Limits electrical current |
| Jumper Wires | Connect components |
| Battery | Supplies electrical power |
| Battery Clip | Connects battery to breadboard |
Understanding the Breadboard
A breadboard is one of the most important tools in beginner electronics and robotics.
Features of a Breadboard
- No soldering required
- Easy to connect components
- Easy to remove and replace parts
- Safe for student projects
- Useful for testing circuits quickly
The breadboard contains internal metal strips that connect rows and columns electrically.
Breadboard Power Rails
| Rail Color | Function |
|---|---|
| Red Line | Positive Supply |
| Blue Line | Ground/Negative |
These rails help distribute electrical power across the breadboard.
What is an LED?
LED stands for Light Emitting Diode.
It is an electronic component that glows when electric current passes through it.
LED Terminals
| Terminal | Description |
|---|---|
| Anode | Positive terminal |
| Cathode | Negative terminal |
The longer leg is usually the positive terminal, while the shorter leg is the negative terminal.
LEDs only work when connected with correct polarity.

Importance of the Resistor
A resistor protects the LED from excessive current.
Without a resistor, too much electricity may flow through the LED and damage it permanently.
Why Resistors are Necessary
- Prevent LED burning
- Control current flow
- Improve circuit safety
- Stabilize electrical operation
The resistor is connected in series with the LED.
Understanding the Push Button Switch
The push button acts like a switch.
When pressed:
- The circuit closes
- Current flows
- LED glows
When released:
- Circuit opens
- Current stops
- LED turns OFF
This same concept is used in many real-world electronic systems.
Step-by-Step Circuit Connections
Step 1: Place the Push Button
Insert the push button into the breadboard carefully.
Step 2: Add the Resistor
Connect one terminal of the resistor to the push button terminal.
Step 3: Connect the LED
- LED positive terminal connects to resistor
- LED negative terminal connects to ground rail
Step 4: Connect Jumper Wires
Use jumper wires to connect:
- Push button to battery positive
- Ground rail to battery negative
Step 5: Connect the Battery
Attach the battery clip and power the breadboard.
Step 6: Test the Circuit
Press the push button.
The LED should glow when the button is pressed and turn OFF when released.
How the Push Button LED Circuit Works
The project demonstrates a complete electrical circuit.
Working Principle
| Condition | Result |
|---|---|
| Button Pressed | Circuit Closed |
| Current Flow | LED ON |
| Button Released | Circuit Open |
| No Current | LED OFF |
This teaches students how electrical control systems operate.
Role of Current Flow in the Circuit
Electricity always flows through a complete path.
The push button controls whether the path is complete or broken.
This is one of the most important concepts in electronics and robotics.
Why Breadboards are Important in Robotics
Breadboards are widely used in robotics because they simplify circuit building.
Advantages of Breadboards
- Fast prototyping
- Easy testing
- No permanent wiring
- Safe for beginners
- Reusable for multiple projects
Robotics students often use breadboards before creating permanent circuits.
Practical Applications of Push Button Circuits
Push button circuits are used in many real electronic systems.
Common Examples
| Device | Use of Push Button |
|---|---|
| Doorbell | Rings when pressed |
| Elevator | Selects floors |
| Calculator | Inputs commands |
| Keyboard | Sends signals |
| Toy Cars | Controls movement |
| Robotics Projects | Controls actions |
This shows students how simple electronics concepts connect to daily life.
