Hi I want to but a Medium 32x32 RGB LED matrix panel
However I can't find the information of wavelength of this LED.
And using this, how can i modify the wavelength of the LED.
For example, if i need 632nm wavelength, can i modify the wavelength just by controlling with Arduino??
Thanks

It's functionally impossible to change the output spectrum of an LED after it's been packaged.bellzero5 wrote:And using this, how can i modify the wavelength of the LED.
Technically you could decap it, remove the wiring and substrate, vacuum polish it, then cook it at about 1200C in a quartz chamber with appropriate dopants to change the aggregate bandgap potential of the material. It's not a normal DIY project though.
