DIY Color Sensor

It is working on a very simple principle as we are giving all basic colors to the object in front,red,green and blue colors make white light present around us and when the white light strikes any object then it reflects back at different wavelength and hence we see the color of an object,this happens because the vibration reduces when the white light strikes object and hence the white light scatters into 7 colors and every single one changes at different value.Same s done here,firstly all primary colors are emitted by L.E.D s and then the LDR (Light Dependent Resistor) receives the changed wavelength hence giving us the R,G and B values of color of an object!!”
