5 Simple Projects You Can Do With Our Junior PCB Toolkit

Starting with electronics doesn’t have to be complicated. With the Junior PCB Toolkit, you already have everything you need to bring small but exciting projects to life. These projects will help you learn the basics of circuits while giving you something fun and practical to show off.

Here are five simple projects you can try right away:

1. Blinking LED Circuit

The first project almost every maker tries, and it never gets old. With just an LED, a resistor, and a power source, you’ll build a circuit that blinks on and off. It’s a quick way to learn how electricity flows and how resistors protect components.
You’ll use: LED, resistor, breadboard, jumper wires, soldering tools.

2. Light-Activated Lamp

This one’s like magic. Using a light-dependent resistor (LDR), you can make a lamp that turns on in the dark and off when it’s bright. It’s a neat introduction to sensors and how they interact with circuits.
You’ll use: LDR, LED, transistor, resistors, breadboard, jumper wires.

3. Buzzer Alarm

Want to build a mini alarm system? Connect a buzzer with a switch so that pressing the switch triggers the buzzer. You can later expand this into a door or drawer alarm for fun practical use.
You’ll use: Buzzer, switch, breadboard, jumper wires, soldering tools.

4. Temperature Indicator

With a thermistor, you can design a simple circuit where an LED changes brightness with temperature. It’s a small step into the world of sensors and helps you understand how electronics respond to the environment.
You’ll use: Thermistor, LED, resistor, breadboard, jumper wires.

5. DIY Traffic Light

Recreate a traffic light system with red, yellow, and green LEDs. Control them with switches or design a sequence manually. It’s a fun way to practice working with multiple components at once.
You’ll use: 3 LEDs, resistors, switches, breadboard, jumper wires.

The Junior PCB Toolkit is built to give you everything you need in one box. No missing parts. No confusion about what tools to buy. Just open it up, pick a project, and start making.
