🔬 The 5 Intermediate Projects 1️⃣ LCD Environment Monitor

Students integrate a 16x2 LCD display, implement calibration routines, and apply multi-level conditional logic.

2️⃣ RGB Mood Lamp with Light-Adaptive Dimming

Students use PWM color mixing, proportional mapping, and a custom setColor() function.

3️⃣ Theremin-Style Instrument

Students apply arrays, tone generation, and a two-state state machine architecture to map distance to musical pitch.

4️⃣ Smart Motion Alarm System

Students build a four-state alarm system using compound sensor logic and non-blocking timing with millis().

5️⃣ Environmental Data Logger

Students implement circular buffers, rolling averages, and raw vs. smoothed data visualization using Serial Plotter.

🧠 Core Concepts Covered

• Multi-sensor systems
• State machine programming (switch/case architecture)
• Custom functions with parameters
• Arrays & circular buffers
• Rolling average data smoothing
• PWM & proportional reasoning
• Non-blocking timing with millis()
• Compound boolean logic (&& and ||)
• Sensor calibration routines
• Engineering trade-off analysis

This is true intermediate coding, not repeated beginner content.

🎯 Capstone Challenge

Students design and build their own automated multi-sensor system using:

• At least 2 sensors
  
• At least 2 output types
  
• A 3+ state machine
  
• Custom functions
  
• Arrays
  
• A mathematical formula applied to sensor data
  

Includes planning templates, state diagram requirements, engineering trade-off reflection, and presentation checklist.

📚 Standards Alignment

Aligned to:

• NGSS MS-ETS1 Engineering Design
• CSTA 2-AP-10 through 2-DA-08
• CCSS Math (Ratios, Expressions, Statistics, Functions)

👩‍🏫 Perfect For:

✔ STEM / Engineering electives
✔ Computer Science classes
✔ Robotics clubs
✔ Makerspace programs
✔ Gifted & advanced learners
✔ Project-based learning classrooms

⏳ Time Required

Designed for approximately 8–10 class periods
(5-Week pacing plan included)

🔧 Prerequisites

Students should already understand:

• Basic circuit construction
  
• analogRead() and digitalWrite()
  
• Simple if/else logic
  
• Basic servo control
  

This is an intermediate-level curriculum.

💡 Why Teachers Love This Resource
