I'm not sure i'm on the right board, but any way This picture is just the générale representation of my idea that comes with a question. Al tough it's not SPI compatible yet I need a confirmation that the serial data that will come out will be ASCII compatible. I basically want the binary code to…

Cause it only require 4 extra wire so i save bit's plus think about it, With the '165 you need 4 Arduino pins, without the '165 you need 5, so granted it's an extra pin but the result is a lot simpler and more versatile. your Arduino will have to do this every time you press a key while my syst…

But any way's If you can do better good for you, your solution wouldn't probably not apply to my plan. And also, I have the 192 and the 165 and the 154 plus alot of 173 and 193 and 163 plus the not gate already on my breadboards, why would I wait for delivery time while i have every thing I need to…

N'est-ce pas butyfull 100% compatible [image]

In any instance Graynomade, the only point of the keypad is to enter the value of 2 angles, on a lcd screen, what would be the point to use &h3A to &h3F?

by the end, what i want to do wont require a Arduino board, I'm only using the Arduino to test the SPI bus So that's an entirely different arrangement to the original circuit. I merely pointed out that you could do the original function a couple of different ways all of which required a lot less …

Without using a processor? How do you plan to do that without some quite complicated hardware? I guess you juste dont know how to build a simple process with a few chips. Has I sayed before: Big lack of imagination here it's like saying "I'm not gonna use a hammer to build my house cause it's o…

This guy did it with one pin, but I'm not sure where ASCII comes into it: http://forum.arduino.cc/index.php?topic=19470.msg142584#msg142584

Yeah, but this would require a ADC to décode wich resistance has been used.

A 555, a few counter a few demux, a few register, few compartor and im on my way.
