5 Simple Projects You Can Do With Our Junior PCB Toolkit

Getting started with electronics can feel intimidating, but the truth is, you don’t need to dive into complex circuits on day one. With the Junior PCB Toolkit, you’ve already got everything you need to try out fun, hands-on projects that will boost your skills and confidence.

Here are five simple projects you can make right away with the kit.

1. Blinking LED Circuit

The classic beginner’s project, and for good reason. You’ll learn how resistors work with LEDs, how to place components, and how current flows through a simple circuit. Plus, nothing beats the excitement of seeing that first LED blink to life.
What you’ll use from the kit: soldering iron, resistors, LEDs, breadboard, jumper wires.

2. Light-Activated Night Lamp

Want a small lamp that turns on automatically when it’s dark? Pair a photoresistor (LDR) with a transistor and an LED. The LED lights up when the sensor detects low light.
What you’ll use from the kit: LDR, LEDs, breadboard, jumper wires, soldering tools.

3. Buzzer Alarm System

This project teaches you how to trigger sound using a simple circuit. Hook up a buzzer with a switch, press the switch, and the buzzer goes off. You can expand this later into a door alarm or alert system.
What you’ll use from the kit: buzzer, switch, breadboard, jumper wires.

4. Simple Temperature Tester (Using a Thermistor)

Thermistors change resistance with temperature. By wiring one into a circuit with an LED, you can create a basic indicator, when it gets hot, the LED brightness changes. A fun way to understand sensors and real-world applications.
What you’ll use from the kit: thermistor, resistors, LED, breadboard, jumper wires.

5. DIY Traffic Light System

Use three LEDs (red, yellow, green) and resistors to mimic a traffic light sequence. You’ll practice wiring multiple components and controlling their timing manually with switches, or take it further later by adding an Arduino.
What you’ll use from the kit: LEDs, resistors, switches, breadboard, jumper wires.

The Junior PCB Toolkit is designed for exactly this, giving you the right tools to learn by doing. Once you’ve mastered these basics, you’ll feel ready to explore more complex builds.
