Statements like "that makes no sense" suggest that you didn't yet think thoroughly about the problem. If you study some application examples, you'll better unterstand the concepts behind PIC24 UART design and common interrupt handling schemes. If you have detail questions, I'm willing to help. - - - Updated - - -
I mean, need to understand power or current of it. - - - Updated - - - I think, if your solenoid valves no need to big power,you could connect a battery bank to your circuit. - - - Updated - - - and when you detect power failure,you can trig your valve by -9v
Here is another idea with a fast response when the duty cycle goes to 100%. - - - Updated - - - The circuit needs a diode added to cope better with high duty cycles like in this requirement. This gives more defined logic levels.
The motor is stalled when it begins to run, then it draws 6A. if you limit the current to only 2A then it might not start or it might start running very slowly. Is that what you want? - - - Updated - - - you should detect stall by using micro to look at motor voltage, because it is low w

consider you are having an image with more than one cricket balls of identical color . how can i localize or detect any one particular ball? consider that both ball and background has same color. suggest me the steps involved in detecting the single ball/ suggest me the best algorithm
Have a look at the attached file:- Its working fine:- 93057 If you are using MAX232, change your virtual terminal setting to inverted from normal. And in Proteus you have to specify the crystal frequency. And its not USB ,its UART
I think skin color is the first choice to test and learn, another is about geometry measurement of face because Statistics is begin form very basic idea although it have usage for non ideal application.
There have been several threads here, which will turn up by doing a search on 'oximeter' or 'blood'. - - - Updated - - - In my mind the hard part is to attach a sensor which is sensitive enough to detect blood color, intensity, etc., under the skin. Some combination of a phototransistor (or photodiode), plain light or inf
"o detect both light and dark color object." The lightness or darkness of a colour is its luminance. The wavelength of the reflected light is its colour. You can have a piece of black velvet with a spot of red on it, it reflects very little light but what light it reflects will be red. if you shine a green light onto the cloth it will not reflect

Your algorithm must examine all possible parameters that could let it distinguish road from grass. In terms of visual detection, this would include the differences we ourselves detect. Including color, shape, presence of many vertical elements (as grass has)... There are also things which the human eye cannot see, but instruments can: (...)
Hello everybody, I want to know which device is best to use to detect different colors (RGB) photodiode,photocell,phototransistor ,or any other device ??????? *suggest me the most sensitive one,which is sensitive to the entire visual spectrum Thanks
Hi, I am trying to detect the presence of some objects of different colors using Slotted IR sensor. When the red color object comes, the rays from the transmitter is not blocked and hence the receiver receives the transmitter signal and the object is not detected. So i want to go with the optical sensor in slotted (...)
Ultrasonic distance sensor is best suited for your project. - - - Updated - - - Ultrasonic distance sensor is best suited for your project.
Basically yes. As longs as you are able to detect a color change.

Since you are using a webcam, not all adapter would give the same RGB result for a single color. They might be just the same but they may vary by a point or so which makes detection of color very difficult. Hereby you have to go for a check of the red color ball for its corresponding RGB value. You may say this as a training (...)
Hi, I would like to ask a question on Tilt angle sensing. If there is an application which requires the device to be on the upright position, and should generate an error whenever there is an oblique angle between device?s top direction and the upright direction, what sensor should be used to detect it? I read some arti
hi.. can someone plz help me to detect the R-R interval in ECG in matlab? i really need help as im doing my final year project or you can just give any opinion on how can i do the coding.. thank you so much :) ---------- Post added at 07:01 ---------- Previous post was at 06:01 ---------- [QUOTE=man
you should measure the voltage of the batteries through ADC every 10-30s. You can use oversampling to increase the ADC resolution from 10 bits to 12 or 14 bits. So if the voltage is under some threshold you change the LED color. Also you need some algorithms to detect which kind of battery you have so you change the thresholds according to the type

Hi You will need to add a sensor who will tell you where is start point - like the QRD1313 And the then you can use encoder data to measure direction All the best BObi The microcontroller specialist
My first Thoughts are . This will demand very high resolution camera a lot of processing .Maybe you will have to concentrate in processing an area full of features that the color copiers can not duplicate !. Two or three of this regions will give you some idea od the validity or not of the bill.

Hi, as to the Gm simulation, you can use "DC" analysis to sweep input differential voltage, and detect the output current, and then use "deriv" function in the calculator. for Rout, use "SP" analysis, you can get parameters such as Z11, Z22, etc. and Z22 is what you want. Hope it helps! Added after 5 minutes:[/
