Schnetzl's Lichtsteuerung

Hier ein Video in schlimmer Qualität. Es soll kurz die Grundfunktionen vorstellen. Am Anfang dimme ich jede Farbe manuell über mein C#-Programm ein und aus, dann aktiviere ich den Zufallsautomatikmodus, während dessen Ablauf ich "Tschauuu!" eintippe und es anschließend sende =)

english:
This is a video of my RGB and UV control circuit. The video demonstrates the main possibilities of this circuit, which is developed by myself. So is the software in the PICs and the PC.
At the beginning I set the colour values manually via my C# software. After that I activate the automatic random mode. While this is running I enter "Tschauuu!" (which means byeeeee =) and finally send it.

I translated the info text to english, so I hope everyone will understand what is going on in this video.

Yes and No. =) Because of being a poor student I used single 5mm LEDs in red, green, blue and UV. I got the milky plexiglas for free. The tube was intended for testing the circuit. The circuit was intended to control a wall or a table with RGB LEDs. But the LEDs I need are a bit too expensive for me, so the tube is the only possibility to present the circuit.

Yes, I used PWM from 3 Microchip PICs, controlled via serial port and a small C# Program. The PIC and PC software are written by myself.

wasn das ?

What do you need the photodetectors for? At least it was not my intention to detect colours. Maybe when I have enough time to build a Java application for my mobile phone that analyzes the camera picture and sends the colour data via Bluetooth the the RGB control circuit.

Unfortunately I did not get enough money until today to buy enough LEDs to cover a whole glass table. Maybe next year =)

i'm thinking about that thing and i guess it could be done with 3 photodetectors and 3 filters (RGB), what do you think?

------------------------------

yo tambien al principio crei lo mismo, y creo que eso puede hacerse por medio de 3 fotodetectores y 3 filtros (RGB).

Interesting. Is the light done with 3-color LEDs and pulse-width modulation? (Sorry; German is on my list to learn, but I haven't had time yet.) 8-)

[Schnetzl]

no problem! =)

[aleweber]

Haaa OK!, I think you have built some kind of light detector who shows you the color. I was wrong certainly. Thanks!

[Schnetzl]

There are no sensors at all. The circuitry I built (3 PICs) gets signals from my PC via COM-Port to set the colour value for each colour. The programs in the PICs are written in Assembler, the program in the PC is written in C#.

[aleweber]

What sensors are that?
