光る：Arduino でスマートなナイトライトを作ろう！

In this hands-on, beginner-friendly class, students will learn how to build and code a smart nightlight using an Arduino Uno, a photoresistor (light sensor), and an LED. The nightlight will turn on automatically in the dark and turn off when it’s bright — just like real smart devices!

✅ What will be taught?
	•	How to wire an Arduino circuit using a photoresistor and LED
	•	How to read analog sensor values using analogRead()
	•	How to use if/else statements to control behavior based on input
	•	How to adjust sensitivity and customize the project

🧠 Topics Covered:
	•	Introduction to Arduino and the IDE
	•	Breadboard basics: wiring the photoresistor and LED
	•	Understanding analog input and output
	•	Writing conditional logic in Arduino code
	•	Real-world application of light-based automation

🧭 Class Structure (75 minutes):
	1.	Welcome & Overview (5 mins) – Meet the teacher, introduce the project
	2.	Hardware Setup (15 mins) – Step-by-step wiring of the LED and sensor
	3.	Code-Along (30 mins) – Guided live coding to turn on the LED in darkness
	4.	Customization Time (15 mins) – Students adjust the light threshold and make it their own
	5.	Share & Wrap-Up (10 mins) – Show finished projects, ask questions, discuss next steps

🎓 How I’ll Teach:

I use a screen-share and build-along method so learners can follow every step in real time. I pause often to check for understanding, offer troubleshooting support, and explain why we’re doing something — not just how. Students are encouraged to ask questions and share ideas throughout the session.

💬 Interaction Style:

This class is highly interactive. Students will:
	•	Follow along live with the build and code
	•	Ask questions via mic or chat at any time
	•	Be invited to share their projects, ideas, or customizations at the end
	•	Receive support during troubleshooting checkpoints
