Re: Rasperry pi3 Can not login after installing tight vnc se

I have now even removed tightvncserver from pi through putty and rebooted still it shows login screen? tightvncserver was not causing this? Why it still asks for username and password and cant login using same username password as putty does?

LED on gpio

Hi, I am a software guy with very less knowledge of electronics. This is not a question about Raspberry but general electronics.

What will happen if I connect a 2 volt LED to 3.3 v and GND pin without a resistor? Will that damage my pi or LED? I dont care if that damage LED. :p

Thank you
Sachin

Re: Keyboard problem

But then why it works well when I test it on my laptop with windows os?

Do you mean this has something to do with os configuration?

I have latest noobs rasbian and I have not modified any settings in rasbian. Then?

Raspberry Pi power cable

Where do I get good power cable at reasonable cost? As pi3 has unique power requirement that none of mobile or other devices requires so can not use any mobile charger because they are providing either less or more current than 2.5A with voltage of 5. paying Rs 1000/- for charger is not worth as com...
