Electronic circuits: Simple color mixer circuit using an RGB LED.
| Download RGBColorMixer desktop application (Windows 64bit) | Download RGBColorMixer source code (Lazarus/Free Pascal) |
Description: Simple electronics simulation of color mixing using an RGB LED. The intensity of the 3 internal LEDs is controlled by
3 potentiometers, that vary the voltage across the LEDs. It is supposed that the voltage variation is directly proportional to the LED intensity and that this
LED intensity proportionally corresponds to a given RGB value. Thus if the first and the third poti are set at the maximum resistance (the second one being
at 0Ω), the RGB LED will produce magenta light; if they are set at half the maximum resistance, the light produced will be purple.
Free Pascal features: Trackbars. Using a transparent image as click area. Handling onClick events. Loading pictures during runtime.
Changing label captions during runtime.
