Thread: Java Installation

-

how know if version of ubuntu has java installed?

, if find not, how install it?

open terminal (applications->accessories) , run following:

dpkg -l | grep java

show versions of java packages have installed, if any. if nothing shows up, run 1 of following:

sudo apt-get install sun-java6-plugin (firefox plugin, installs jre)
sudo apt-get install sun-java6-jre (just jre, can run java stuff)
sudo apt-get install sun-java6-jdk (installs jdk in addition jre, can compile java stuff)

there closer-to-foss alternatives (openjdk-6-jre , variants, icedtea6-plugin) if sun eula bothers you, i've never tried them.

hi community, in last days working on project using arduino mega 2560. on planning pin using found bugs in atmega2560-arduino pin mapping . if right there labels (such pwm) in 'mapped pin name' @ wrong row ( mixed pin numbers right one...) in attachment openoffice calc , pdf file corrected table. ( hope ;-) ) i post here tab separated table : code: [select] arduino mega 2560 pin mapping table atmega 2560 pin out arduino mega function nr name function function function mapped pin name function function datasheet 1 pg5 oc0b digital pin 04 pwm 2 pe0 rxd0 pcint8 digital pin 00 rx0 (usart0 receive pin, programming data input or pin change interrupt 8) 3 pe1 txd0 digital pin 01 tx0 (usart0 transmit pin or programming data output) 4 pe2 xck0 ain0 (usart0 external clock  input/output) 5 pe3 oc3a ain1 digital pin 05 pwm 6 pe4 ...

Crossfader Arduino Tutorial

(brightness , color mixing) code: [select] /* * code cross-fading 3 leds, red, green , blue (rgb) * create fades, need 2 things: *  1. describe colors want displayed *  2. list order want them fade in * * describing color: * color array of 3 percentages, 0-100, *  controlling red, green , blue leds * * red red led @ full, blue , green off *   int red = { 100, 0, 0 } * dim white 3 l...
