Learn to code with this electronicly upgraded, super hackable, fidget spinner. Perfect for S.T.E.M. learning projects the Lightino uses an Arduino Pro Micro microcontroller with 8 RGB LEDs and an optical rotation sensor allowing you to program different display features and POV (persistence of vision) effects.
The optical sensor used in the Lightino V3 is the QRE1113. This IR sensor is used for analog output which will vary depending on the amount of IR light reflected back to the sensor. The QRE1113 IR reflectance sensor is composed of two parts – an IR emitting LED and an IR sensitive phototransistor. When the light from the LED is reflected back onto the phototransistor, the output will begin to go lower.
The Lightino STEM fidget spinner comes with 8 RGB LEDs on the board. These can be programmed to produce many different effects in millions of colours.
