1  Using Arduino / Installation & Troubleshooting / Re: Work around required for none opening Arduino IDE on: Today at 01:33:50 am
The only thing I can suggest is as you have a D: drive, download and extract the zip to that drive and run the arduino.exe from that folder on D: Don't put it in C:\Program Files (x86) as I think you can get file permission errors with programs in that folder. AFAIK the zip version of the IDE is self contained and the only files it writes external to itself are the Arduino sketch folder (normally in My Documents) and the preference folder/file stored in your logon accounts AppData\Roaming\Arduino folder.
This may be different on 8.1.
Other than this I have run out of ideas. I don't think you need to disable the Firewall and Defender though but try without first.

The file setup_Arduino_ERW_1.0.5_20130524_no-java.zip you tried to install does need a version of Java to work. The no_java on the end of the filename means it does not have java files included in the download (making the download file smaller) and relies on the user already having a version of Java installed.

The only thing I could suggest is you remove all previous installs of Arduino IDE and ALL java SDK's and updates just in case they are effecting the installed IDE. Download the zip file version of the current Arduino IDE from here and extract the zip file to a folder. The downloaded zip includes an *internal version of Java for running the IDE and should work fine without having a full version of Java installed. Once the zip is extracted navigate to the extract folder and open the arduino.exe
If that does not work then I can only assume the problem is with 8.1, file access permissions or some other software like anti-virus, anti-malware running in the background and preventing the IDE from launching/running.
You could also try running the arduino.exe in compatibility mode (if Windows 8 still has such an option).

Don't see the relevance of CRT link.  smiley-confuse

Are you using the EXE or the ZIP version of the file? I have never used the installer version and zip has always worked fine for me.
Maybe your anti-virus/malware is blocking something or if you have the full version of java installed it is messing with the inline version in the full install. Certainly the zip install should not need any administrator rights access and should run as limited user (nothing pops up for me on Vista & 7).

Datasheet says default baud rate is 9600,8,N,1 and your code is using 4800 baud try changing it and see what happens.

Well oil beef oct.  They've only gone and done it smiley
Must be a local dialect as I always knew it as 'Whale oil beef hooked'  smiley-grin

Have you installed the IRremote.h & IRremoteInt.h libraries correctly (if at all)?
8  Using Arduino / Sensors / Re: Read PWM light signal with TSL250 sensor only when PWM is high on: September 30, 2014, 01:45:01 am
To be sure the problem is from the sensor you should try driving the LED(s) from a simple voltage divider and steady power supply so you have no PWM signal and see if the results settle down and behave as expected on the sensor. If they do then maybe using RC circuit on the LED(s) instead of on the sensor is the answer or at least you would know the digital pot route is more likely to work.
9  Using Arduino / Project Guidance / Re: Is Teensy the answer for video processing ? on: September 30, 2014, 01:23:18 am
This looks promising, but too much hoopla (TV?)  and little tech stuff.
I'll take a closer look at forums, they tell the real story.
Care to translate this into English please.  smiley-confuse

I am basically trying  to do object recognition , not just movement. I got is started on PC, now I need to "scale" it down to some portable device.
What software are you using on the PC (maybe OpenCV) as it has Linux versions that may compile on a RPi and the RPi has camera.


10  Using Arduino / Project Guidance / Re: Is Teensy the answer for video processing ? on: September 29, 2014, 10:22:18 am
For video processing (and possible camera connection) I would think the Raspberry Pi would be a better option but to be certain you will need to expand on what video processing your expecting to do and how quickly you expect to do it.
11  Using Arduino / Project Guidance / Re: Is it possible to make a color sensor out of an RGB led and phototransistor? on: September 29, 2014, 02:00:50 am
I want to build a simple color sensor, can i do that with and RGB led and a phototransistor?
 Any tutorial or suggestion?
As an exercise probably an interesting thing to do/learn but from a practical point of view a colour detector can be very cheap
12  Using Arduino / Project Guidance / Re: ATTINY45, Solution/Substitution for FreqCount Library? on: September 24, 2014, 04:55:09 am
The code you have should be doing what you want. The only reason I can think the values vary so much is the pin is floating, the signal is not a clean TTL level or not a constant 50% duty cycle. You could try either a pullup or pulldown resistor on the input pin to see if the results stabilize. Pullup could be done on the chip by using pinMode(pin, INPUT_PULLUP); instead of pinMode(pin, INPUT); but you will maybe need to use LOW in the pulseIn instead of HIGH. For pulldown use the same code you currently have (INPUT) and put a 10K resistor between the input pin and ground.

How long will the timing period be for? You can use microseconds instead of milliseconds but the value will overflow after about 70 minutes.
14  Using Arduino / Project Guidance / Re: ATTINY45, Solution/Substitution for FreqCount Library? on: September 24, 2014, 01:30:52 am
Code:
// the loop routine runs over and over again forever:
void loop() {
  duration = pulseIn(pin, HIGH);
  // read the input pin:
 // int pulse = digitalRead(pin);  //<<<<<<<<<<<<<<
  // print out the state of the button:
  //Serial.println(pulse);  //<<<<<<<<<<<<<<<<<<<
  Serial.println(duration);  //<<<<<<<<<<<<<<<<<<<
  delay(1);        // delay in between reads for stability
}
Your reading the pin using pulseIn and doing nothing with the result but then read the pin using digitalRead and print that result.

Well done to everyone who helped solve the "birthday present" problem. smiley
