Transistor Power: Night Light Challenge (TryEngineering)

#IEEE #electronic-circuits #creativity #application

TryEngineering, through initiatives like the STEM Grant, is dedicated to inspiring and empowering young minds to pursue careers in science, technology, engineering, and mathematics (STEM). Through its program outline, the IEEE PSB of Nepal has designed a program named STEMfluence: Think, Tinker, Thrive. It is a two-day, hands-on learning event targeted at Grades 9 and 10 students. STEMfluence bridges this gap by combining theory, visualization, and practical experience, recognizing that abstract scientific concepts can feel disconnected from real-world applications. Students use beginner-friendly tools like Tinkercad and lesson plans such as Keysight’s "Transistor Power: Night Light Challenge" to build actual electronic circuits, moving beyond textbooks into real-world tinkering. Key sessions such as Transistor 101, Creative Circuits, and Exploring Transistors allow students to engage in interactive quizzes, simulations, and design challenges. The event emphasizes project-based learning, aiming for measurable improvement in technical skills while also building teamwork, communication, and innovation abilities. Students work in teams, guided by IEEE volunteers, to create and present night light prototypes, integrating creativity and critical thinking. Beyond technical knowledge, STEMfluence connects students to real-world STEM careers and influencers, inspiring them to view STEM as a vibrant and collaborative journey rather than a solitary academic pursuit.

This two-day interactive workshop introduces students to the fascinating world of transistors, photoresistors, and circuit design. Through a hands-on, story-driven approach using real-world analogies and digital simulation tools like Tinkercad, participants will build foundational knowledge in electronics and engineering design processes. The event is designed to spark curiosity, build practical skills, and foster creative problem-solving.

Day 1: Understanding the Magic of Transistors

• Students experience how fast a transistor can switch compared to human effort, using a fun light switch activity.
  
  

• They learn the basic science behind transistors: what they are, how they work, and why they are crucial in modern electronics.
  
  

• Real-world analogies like the water tap are used to simplify complex concepts such as signal amplification and switching.
  
  

• Participants explore the basic structure of a transistor (Base, Collector, Emitter) and different types (NPN and PNP).
  
  

• Introduction to Moore's Law and the role of transistors in the advancement of technology.
  
  

• Students build simple circuits in Tinkercad, observing how small signals control larger outputs using transistors.
  
  

• Key concepts of photoresistors (light sensors) and LEDs are introduced, demonstrating how circuits react to environmental changes.
  
  

• The day wraps up with a Kahoot quiz and interactive activities to reinforce learning.

• Primary Design Challenge: Guided Project building

Day 2: Building Smart Solutions

• Quick revision of Day 1 concepts.
  
  

• Students design and simulate a smart night lamp using Tinkercad, based on their understanding of transistors and photoresistors.
  
  

• Transition from simulation to real hardware assembly, guiding students through practical building and troubleshooting.
  
  

• Emphasis on the Engineering Design Process: exploring, designing, testing, learning from failures, and iterating improvements.
  
  

• Teams collaborate to create working tangible circuits, reflect on their designs, and discuss challenges faced.
  
  

• Students are encouraged to innovate by designing their transistor-based projects, such as automatic street lamps, light-activated toys, or motor switches. Secondary Design Challenge: Team-Based Project Building

• Final presentations allow students to showcase their designs, teamwork, and creativity.
