Color pdf sensor

S3 and S4 are photo diode selection pins. They are used to select different photo diodes which are associated with different color filters Red, Blue, Green and Clear. The following table shows different combinations of S3 and S4 for different types of photo diodes. The following image shows the real time Color Sensor Module. A simple Color Sensor using Arduino is developed in this project. The color sensor module senses the color in its surroundings.

The working of the project is explained here. The intensity of each color is represented as a frequency. We have to use the S2 and S3 pin on the color sensor to select the type of photo diode i. This will help us to calculate the frequency of the output signal. The same process is repeated for all the three photo diodes: R, G and B.

Additionally, this information can be used to identify the color placed in front of the sensor and display its color on the LCD and also light up the corresponding LED.

Sir, can i replace arduino mega with arduino uno? And can you pleaae show me the code? Ill be needing your answer for i will be implementing this project. Hi, Yes. You can replace Mega with UNO. Sir,this is a very good project! So what are the changes that we make in circuit diagram and the code?? Can you please send me the code asap as ill be implementing this project.

Elizabeth Howell. Color sensor 1. Color theory:- Primary and secondary colors: Primary colors:- Primary colors are sets of colors that can be combined to make a useful range of colors. For human applications, 3 primary colors are usually use, since human color vision is trichromatic, primary colors subdivide into Primary Color Additive Subtractive.

Secondary color:- A secondary color is a color made by mixing two primary colors. Subdivision of primary color:- Primary colors dividein 2 parts. Additive primary:- An additive color model involves light emitted directly from a source or illuminant of some sort Combining one of these additive primary colors with another in equal amounts produces the additive secondary colors Combining all three primary lights colors in equal intensities produces white.

An additive color model in which RED, GREEN, and BLUE light is added together in various ways to reproduce a broad array of colors Used in sensing representation, and display of images in electronic systems, such as televisions and computers. Subtractive primary:- A subtractive color is based on absorption phenomenon. Each color is caused by subtracting that is, absorbing some wavelengths of light and reflecting the others.

This model explains the mixing of paints, dyes, inks, and natural colorants to create a full range of colors. System introduction:- Block Diagram Light rays from a color light source fall on the optical components of the Color Sensor. The optical components filter and focus the rays on the optical sensors.

The output of the sensors is processed by the electronic circuitry and the corresponding color output is obtained. Photodiode is used in optical component. Electronic System :- 6. For a single IR sensor, only one channel is enough. So, in answer to your question: yes, it can detect other colors.

However, I should warn you that the sensor is a bit tricky to use, as the results vary depending on the light intensity and the distance to the object. Could you post the code for adding extra colours to this? You need to use the first code to get values with yellow. Try several times in order to have significant data for that color. Then, you need to see the relationship between the R, G, and B values when you measure the yellow color, and add that logic to the second code.

Take a look at the code of this project that checks for yellow, and see if you can sort it out: howtomechatronics. Sir, I want to know whether this tcs color sensor module is compatible with ARM processor?

Yes, it should probably work. If you are programming it in a high level language, you may be able to adapt this code to make it work for you. How can I find out the detected color from the frequency output? How to measure the frequency output?

I think it is in the form of square pulses. Then how will I obtain the frequency? You need to replace the XX with your own values. Thank you, I have made this experiment.

May I copypaste your code and part of this webpage and write it on my USB for archiving my project? You can use the content of this project if it is for personal uses only. You cannot distribute this content online. You can use part of the content as long as you give credit to our blog.

How to make a Maze solving,color detection,payload unloading and payload unloading car with arduino. Hi Vasco. The temperature sensor can read any color. Each color results in different output readings in the red, green, and blue frequency. Hello, this is great work!

I would like to use it but it has to be very fast 0. Thanks a lot! It gives instantaneous readings but they fluctuate a bit. But you can try it and see what you get. You need to replace XX with your own values.

Please read the full tutorial to understand how to get those values. Can I just say, you guys Sara and Rui are my heroes. This is like the 8th tutorial I use from you. Keep it up! I have a monitor displaying a 2cmx2cm box. This box change color. I need to build a circuit that I can attach to the screen of that monitor so that the circuit can alert me when the box change color.

Do you think these sensors on this article can do that job? I was told that since the source of the color is a computer monitor, not all sensors would work. I cannot install a software the machine to alert me when the box change color. Hi Mark.
