Categorisation
Props & Materials Required
- •Glass triangular optical prism set
- •High-power white LED beam spotlight
- •TCS3200 RGB color sensor (scans rainbow spectrum colors)
- •ESP32 controller board with OLED display
- •DFPlayer Mini MP3 module + 3W speaker
Step-by-Step Instructions
Shine White Light through Prism
Shine a narrow white LED beam through the triangular glass prism.
Observe Rainbow Dispersion
Watch white light refract and split into 7 rainbow colors (VIBGYOR) on a white screen!
Scan Rainbow Colors with Sensor
Pass the TCS3200 color sensor across the rainbow band. Sensor identifies Red, Orange, Yellow, Green, Blue, Indigo, Violet wavelengths.
Wahida Story & Naval Command
Speaker plays Navy Officer Wahida Prism's story: 'Like a prism reflecting 7 colors, bring honor to the nation!'
Why It Works & Notes
Commander Wahida Prism was the first woman to command a naval parade. Exploring why her father named her 'Prism' (which reflects 7 colors) by splitting white light with a real glass prism links inspiring history with optics.
