A traffic light controller in a custom 3D-printed case — the student designed every part, soldered the board, and programmed the logic.
Course Overview
The complete maker process from idea to product. Students design a 3D housing in Tinkercad, create a PCB layout in EasyEDA, solder components under teacher supervision, test the circuit, and assemble everything into a finished working model. Real engineering — sized for young makers.
What you'll learn
- Understand the full steps of making a real electronic product
- Use Tinkercad to create a simple 3D model for a housing or case
- Understand what a PCB is and why it replaces a breadboard
- Use EasyEDA to create a simple PCB layout with pads, tracks, and labels
- Prepare a PCB design for printing or manufacturing
- Practice safe soldering under teacher supervision
- Test a PCB after soldering to verify all connections work
- Assemble a PCB inside a 3D-printed housing
- Build a working traffic light controller as the final project
- Present the finished product and explain the entire design process
Final Outcome
A working traffic light controller inside a custom 3D-printed housing — designed, soldered, assembled, and presented by the student.
The Final Project
A traffic light controller in a custom 3D-printed case — the student designed every part, soldered the board, and programmed the logic.
