only the green led are always on and the blue and red don't do any thing
also the LDR don't give any thing to the IC ( that what i think )
coz no change in the volt that gos to the led
i need help to get color sensor that sens with cloth colors and give me sens in any thing coz i want to interface that with the pc that is my final year project plz help me asap
i want to make this project or another one to sens the colors and give me data on the pc say the degree of this colors and which it contained of]]> Mon, 18 Feb 2008 16:24:57 -0800 http://www.8051projects.net/forum-t6017.html http://www.8051projects.net/forum-t6017.html ]]> contact@nospam.com (Ajay Bhargav) Wed, 20 Feb 2008 04:07:54 -0800 http://www.8051projects.net/forum-t6017.html http://www.8051projects.net/forum-t6017.html all this time and no one want to help me ]]> contact@nospam.com (Ajay Bhargav) Tue, 19 Feb 2008 14:48:45 -0800 http://www.8051projects.net/forum-t6017.html http://www.8051projects.net/forum-t6017.html ]]> contact@nospam.com (Ajay Bhargav) Thu, 21 Feb 2008 08:22:41 -0800 http://www.8051projects.net/forum-t6017.html http://www.8051projects.net/forum-t6017.html here is my circuit

plz tell me what wrong in it??
and some ppl told me that i need to make micro controller circuit ??? is that right ?? and if u can tell me what is the rcx mean ?? and if it program or circuit can u give it to me ??
and where i can see the results ??
also tell me what ADC i can use and where i should connect it and how i can switch between colors?]]> contact@nospam.com (Ajay Bhargav) Tue, 11 Mar 2008 09:07:03 -0700 http://www.8051projects.net/forum-t6017.html http://www.8051projects.net/forum-t6017.html http://www.robotroom.com/ColorSensor.html]]> contact@nospam.com (Ajay Bhargav) Sat, 01 Mar 2008 02:56:12 -0800 http://www.8051projects.net/forum-t6017.html http://www.8051projects.net/forum-t6017.html here is the circuit]]> contact@nospam.com (Ajay Bhargav) Sat, 01 Mar 2008 01:52:26 -0800 http://www.8051projects.net/forum-t6017.html http://www.8051projects.net/forum-t6017.html i mad the one that i linked it to u but it didn't gave me what i want.
i need circuit to sins with colors then give me reading how much is this color.
mmm...
like I put a piece of cloth with a specific color to the show who shall contain metres from the red How Green How Blue (basic colors)
can u help me in that plz ]]> contact@nospam.com (Ajay Bhargav) Sat, 01 Mar 2008 09:30:39 -0800 http://www.8051projects.net/forum-t6017.html http://www.8051projects.net/forum-t6017.html the CdS sensor o/p is connected to ADC, you have to switch each LED one by one.. lets say blue LED, the read ADC o/p then switch green read ADC value, then red... and read ADC again.. now you have got individual amount of primary colors present in the i/p color.

now you can test the o/p of ADC with different colors...]]> contact@nospam.com (Ajay Bhargav) Sun, 02 Mar 2008 06:31:13 -0800 http://www.8051projects.net/forum-t6017.html http://www.8051projects.net/forum-t6017.html contact@nospam.com (Ajay Bhargav) Thu, 20 Mar 2008 21:01:30 -0700 http://www.8051projects.net/forum-t6017.html http://www.8051projects.net/forum-t6017.html First of all.. the circuit you are using have no information on how to interface it with a controller.

All you need is LED board from that circuit.. the LEDs can be connected to any port pin of controller and LDR's O/p goes to ADC. switching of LEDs is simple... you just need to make that port pin high, LED will glow.
Switching will be done in intervals.. you need to take 3 samples per second, one for each sensor. set the timer interrupt for 300mS, so whenever 300mS are over, start ADC and get the value and switch to next sensor.. once you are done taking these three samples process your readings.. check the values you are getting from ADC.
lets say readings are 200(R), 10(G), 30(B) - so your i/p color is more of red..]]> contact@nospam.com (Ajay Bhargav) Thu, 20 Mar 2008 23:36:24 -0700 http://www.8051projects.net/forum-t6017.html http://www.8051projects.net/forum-t6017.html can u give me simple schismatic for what u say plz
