led

I have been looking for the ability to disable and enable the LED notification light through code. I saw this thread Disable/enable notification led , but it is quite old and I was wondering if the new API versions has some support for turning it off completely. I was wondering if the new API versions has some support for turning it off completely You cannot enable or disable the LED behavior through the Android SDK, except within your own app, where you control what any Notification does that you raise. You can only control the led if your app raies a notification when no other apps have

I'm trying to implement a 1 second red blinking at the front led whenever the user presses a certain button. But I'm having trouble finding documentation, tutorials or even code-examples on how to access and work with the front led (by that I mean the led located adjacent to the "selfie" camera and the touch screen). I've seen examples to work with the flashlight and Camera class (deprecated) but I believe that's not what I'm looking for. There is no direct access to the front L.E.D. You can schedule Notifications with custom colours for the L.E.D. Notification.Builder builder = new

I am trying to control 4 LEDs and getting analog input from 4 contacts. The program is written in java, so to gain acces to the functions of arduino, such as AnalogRead() and setting an LED to high or low, would importing the processing library let the program use those functions? I was also wondering, if the program, will be transferred to the arduino it self, or the java program will just pull the data from the pins? Update : My suggestion is to first try communicating the Arduino with Processing by youself. This is what I describe below. If you want to jump straight to controlling the

I'm trying to use a Notification that also uses the Notification LED on my S3, but for some reason the color will always be blue (I guess it's the default?). I tried to use different colors but nothing changes. Other apps (like Whatsapp, Gmail and Facebook have no problems with showing a different color light). Notification.Builder noteBuilder = new Notification.Builder(context) .setAutoCancel(true) .setPriority(Notification.PRIORITY_DEFAULT) .setSmallIcon(R.drawable.ic_launcher) .setContentTitle(ContentTitle) .setContentText(ContentText) .setLights(Color.YELLOW, 500, 500) ; Intent noteIntent

I've currently managed to get my LED to cycle through eight colors that I've selected. Everything is working correctly, except that I want to go for a more natural feel, and would like to fade / transition from one color to the next, instead of having them just replace one another. Here's my code so far: int redPin = 11; int greenPin = 10; int bluePin = 9; void setup() { pinMode(redPin, OUTPUT); pinMode(greenPin, OUTPUT); pinMode(bluePin, OUTPUT); } void loop() { setColor(250, 105, 0); // Yellow delay(1000); setColor(250, 40, 0); // Orange delay(1000); setColor(255, 0, 0); // Red delay(1000);

I have coded an App that can convert normal Text like : "Hello my Name is XY" into points and strokes ( ..-. ; --.- ; . ; - ; etc etc) Now I want to Convert these points and stroke into light flashes with the lenght of 0.3 sec for points an 0.6 seconds for strokes. also there is a pause with the length of a point after each point or stroke, a double pause after each Word, and a tripple pause/break after each sentences. The breaks are also implied into my code. The problem is now that the light strokes aren't different enough. Because the Idea behind it is to convert the Light flashes via an
