mclien were you succesfull on the keyboard attempt?

Awol
I'm sort of new on this , any specific Indexing and or table tutorial that you recommend. I'm guessing is some sort of variable that u can use a a flag right?

Ok Marco
Let me give a shoot this weekend.
3  Using Arduino / LEDs and Multiplexing / LED ONtime ≠ OFFtime WITHOUT DELAY on: September 12, 2012, 07:27:13 pm
Hello I'm Trying to do something like the signal below, but all the code that I have found
uses the same ON time for the OFF time using mills, What I have not found is a reference or code to handle them independently.
It's very easy to do it with the delay function, but I need to run something else, While the leds do this.
Not very experienced on this on using loops or while's yet, but anything goes.

//Activate LED's ON and OFF at independent time ONtime ≠ OFFtime.
//Start With LED1 and then LED2..
//Without USING DELAY..


int led1on= 500 // means that led1 will turn on 500ms
int led1off= 200 // means that led1 will turn Off 200ms
Int led2on= 400 // means that led1 will turn on 500ms
Int Led2off= 200 // means that led1 will turn on 500ms

For this specific tutorial  the diagram calls for a 220 ohm resistor but the sketch mentions it's a 10-kilohm.
Also the sketch has a led interface using pin12 that suppose to turn off when the switch is pressed, but the schematic
doesn't reflect this connection.

Also the Link on the Sketch is wrong
IS:
http://www.arduino.cc/en/Tutorial/KeyboardButton

S/B:
http://arduino.cc/en/Tutorial/KeyboardMessage

IS this Sketch the correct one?
