Today my daughter and me continued to study our animal encyclopedia. We found the chameleon. I tried to explain her that some species adjust their colors for camouflage in accordance with the vision, but she did not understand, so I built a simple robot chameleon during her afternoon nap.

 

Schematic

Materials

  • Arduino Uno or Mega
  • Arduino prototype shield
  • Male pin headers
  • RGB LED
  • 3 x resistor 330R
  • GY-31 (TCS3200 breakout board)
  • 20cm Ribbon cable (8 wires)
  • Heat shrink tube
  • Ping pong ball
  • Two-component putty for the tail and head of the chameleon
  • Tin solder

Tools

  • Soldering iron
  • End-cutting pliers & scissors
  • Battery drill (5mm drill)
  • Cigarette lighter
  • Waterproof markers for the paint of the chameleon

Future ideas

  • Add temperature sensor to adjust color
  • Add capacitive touch sensor to adjust color

My daughter is very excited about the little robot chameleon and played a long time with it. She does now understand that some chameleons adjust their colors for camouflage in accordance with the vision and she learned some names of colors in different languages (German and English).

The code is running properly but the leds on the sensor are not flashing as seen in your video.

Please help me out at your earliest convenience.

Well done Markus, very efficient and a great way to keep the little ones busy for hours :-) 

Does your daughter also understand and speak Chinese?

Yeah, she talks Chinese like a Chinese :)

Nice way to teach colors...  Great idea.

Cool stuf Markus and congrats on the HaD exposure. What a fun learning experience!

One day you will be able to buy an oled light fitting the size of a wall and instead of painting the living room, you just use Markus's chameleon to pick whatever colour you feel like today.
What an awesome daddy.

Very innovative and creative Markus Sir! Loved the chameleon and the instant colour changes!
