  4. Display real-time temperature on screen

Key Concepts:

  • Sensor data acquisition
  • Conditional logic for color mapping
  • RGB color control
  • Loop structures

Project 3: Simulated Community Street Light System​

Objective: Build an automatic street light system using a light sensor and 4 full-color LEDs (blue light). The system automatically adjusts the number of lit LEDs based on ambient light intensity (darker = more LEDs on) and displays real-time sensor values.

Required Hardware:

  • Steamania JoyKit V2 (Main Controller)
  • TCS34725 Color Sensor (for ambient light detection)
  • 4x WS2812B Full-Color LED Modules (configured as blue street lights)

Core Tasks:

  1. Read ambient light intensity from sensor
  2. Implement multi-level threshold logic
  3. Control 4 LEDs independently based on light level
  4. Display real-time sensor values on screen
  5. Automatically adjust LED count (0-4 LEDs)

Key Concepts:

  • Analog/digital sensor reading
  • Multi-level conditional branching
  • Array-like control of multiple outputs
  • Real-time data visualization
  • Threshold-based automation

Project 4: Digital Calendar​

Objective: Build a digital calendar using buttons and a 4-digit 7-segment display. Initially display "0000", and switch between displaying the year "2026" and the month-day "0131" by pressing a button, cycling continuously.

Required Hardware:

  • Steamania JoyKit V2 (Main Controller)
  • 4-Digit 7-Segment Display Module
  • Push Button Module

Core Tasks:

  1. Initialize 7-segment display to show "0000"
  2. Implement button press detection
  3. Toggle between year display mode (2026) and month-day display mode (0131)
  4. Continuously cycle through display modes

Key Concepts:

  • Multi-digit 7-segment display control
  • State management
  • Button debouncing
  • Display mode switching

Project 5: Voice-Controlled Electronic Candle​

Objective: Design a voice-controlled candle using a sound sensor, full-color LED, and music module. The LED defaults to flashing green light. Blow once to switch to flashing red light (simulating lighting). Blow again to extinguish the LED and play music (at least three notes), then remain extinguished, simulating blowing out the candle. The process cycles.

Required Hardware:

  • Steamania JoyKit V2 (Main Controller)
  • Sound Sensor Module (Microphone)
  • WS2812B Full-Color LED Module
  • Buzzer/Music Module

Core Tasks:

  1. Initialize LED to flash green light (default state)
  2. Detect sound trigger (blowing air)
  3. Switch to red flashing mode on first blow (candle lit)
  4. Detect second blow to extinguish LED and play music
  5. Cycle through all states continuously

Key Concepts:

  • Sound detection and triggering
  • State machine with multiple modes
  • LED flashing patterns
  • Music playback integration
