I'm just a newbie Electronics student so I'm still having troubles with basit circuits.
I have a homework which requires me to make RGB LED emit different lights for different 2-bit inputs. For example, blue for [10], red for [01]. The though point is it has to be wireless via Laser LED.
I'm supposed to generate signals with different duty cycles for 1 and 0. It seems like easier part to me. I plan to use capacitor, op-amp, diode to generate signals for 1 and 0. Then I will sum them according to my input and I will obtain different signals for each input.
But question is how can i make a receiver to calculate this signal and make RGB LED emit correct color of light.
