Yet another Logic Gate Kit to let you play with binary gates like those used in computer construction. The real innovation here is the use of flexible "wire" elements that simplify hooking up the gates.
I've modeled a binary adder circuit for you to play with. Click on the rectangular switches to turn them on or off. All elements are draggable so you can make other circuits. It's easiest to work with in presentation mode.
The signal color is red which is transmitted from the inputs (sensors) of each gate to the output according to the usual truth tables.
Each wire consists of two sprites that communicate using the new Scratch 1.2 features. The wires are NOT bi-directional, make sure the green (sensor) end is placed on the signal you want to transmit. Also be careful that sensors from different elements don't shadow each other; try not to stack them on top of each other.
If you want to change the direction an element is pointing, hold the mouse over it and use the arrow keys.
Let me know of any suggestions or errors and, as always, comments are welcome.
Thanks to SimpleScratch for his inspiration.

Nice! I could only make one that did 1 or 2 as your awnser.
where are the NOR and NAND gates?
I didn't give you any...but you can make them up from NOT and OR, AND, XOR, etc.
(view all replies)what do you do. its still cool
You can build what are called logic circuits...which are used in computers (very low level stuff!). Check out Wikipedia: http://en.wikipedia.org/wiki/Logic_gate">http://en.wikipedia.org/wiki/Logic_gate
I love electronics!!! I made a project about resistors! Can u look @ it plz?
I made a similar project, "not-so-simple circuit"
ell p2s as you might have read on my reply to richiepoo i know know whgat resitors and capacitors do and know whast logic gates bacically do
That's cool - electronics is a fascinating field of study!
(view all replies)Amazing, most impres are I about the resizeable wires connecting
oh that's Super easy to do
clever! I like how it allows you to move the wires! simple Boolean logic is always a fun thing to fool around with.
Logan, if you mess with electronics and don't know what a resistor does than what do you mess with. lightbulbs? Im not saying this to be mean, I just want to know because I "mess" with electronics too.
yeah well i'm only 11 and only messed with swichwes and LEDs (and i know what LED stands for) but just recentally found out how to use resistors and capacitors and i know what logic gates do
(view all replies)WOW this is really cool whats more i can actually understand it =)
i mess with electronics(i still need to learn about reisisters and capacitr and that stuff) but this dosent really make sence at all
cool game ps . thanx for the advice on my game - ball play - sure to do that in v2!
WOW Great job!!!
WOW, Paddle! You have make so much fun here on scratch!
could you teach me how to do string art
Very nice!
Excellent.
It's on the Show and Tell Forum now under New Technique - Flexible Wires for Toolkits. Let's take the discussion over there. (link to forums)">(link to forum)
If your project is ment to be run in non-presentation mode and the flashing bothers you, you could try removing the Wait in the Wire Drawer. Or, you could make it update when you do your heart beat but then the wires wouldn't follow the wire terminal sprites as they were dragged around.
I prefer the forums for chatting about projects because I think it gets a wider range of people involved in discussion - did you post any message about your version there?
They probably are but too fast for the eye to see. I think presentation mode runs faster because it doesn't have to show you all the program blocks executing and such.
I wonder why the wires don't flash in presentation mode!
Love the flexible wire!!!! (But where have you hidden the code so I can use it back in my version?) :-)
that is so awsome i love it:)
Added the ability to turn the gates in different directions. Hold the mouse pointer over the elment you want to turn and use the arrow keys.
Well, they are not perfect, but they do make constructing networks much easier. It would be nice if they had a frozen mode so they could be dragged around as a unit instead of one end at a time. I'd also like to be able to position the mid-section manually at times to make it easier to see the connections. That would be tough to do, though, as the mid-sections are really just lines drawn by the pen and are not selectable by the mouse. All things to work on but I'm glad you like them!
Wow, the flexible wire connectors are really something else! They make this the first logic kit in Scratch that's actually usable as a piece of 'stand alone' software.
Could be. If there is enough interest, I'd be happy to add more gates in, NAND, NOR whatever. I'm a mechanical engineer so I don't really have a good feel for what EE folks like or want.
? Wow! very unusual! I couldnt figure this out, but this obviously was very well worked on! Good job yet again!
To brainy!Can't figure out!Beep!
very interesting, Paddle2See! Useful for teaching electronics!
