Web Browser Arduino Simulation: In this instructable we're making a led chaser using 123D Circuits.io's breadboard virtual protyping and Arduino simulation.

UPDATE Instructables user mattpbooth has updated the code and is hosting it on github: Thanks Matt! UPDATE Replaced a println with print (derp). UPDATE Remade all code from scratch.

Remade 'ible code section; Now includes a 'Processing COM port config for dummies' Ladies and gentlemen, I proudly present 8bit pleasure. Yours for the grabbing! Whether you use GNU/Linux, Mac OS X, or Windows the USB NES controller is compatible.

Will this in any way alter the controller? Nope, the controller will stay the same so you can still use it on a real NES But I don't have an arduino;_; You can use the parallel port: Buy an arduino: Or a retrozone NES kit. UPDATE Instructables user mattpbooth has updated the code and is hosting it on github: Thanks Matt! Hey guys, I've completely rewritten the code and it should work now flawlessy. The only adjustment you might need to make is to the Processing Sketch; you need to adjust which COM port it should use. To do this please follow these steps carefully! Steps 1 ) Disconnect the Arduino if it's connected.

2 ) Run the Processing sketch, it WILL(!) display an error. Installibng usb adaptor for mac book pro. 3 ) Check the console (black box with text at the bottom of processing) 4 ) In the console will be a list of active COM ports; Serial list WARNING: RXTX Version mismatch Jar version = RXTX-2.2pre1 native lib Version = RXTX-2.2pre2 [0] 'COM3' End of serial list 5 ) As you can see currently COM3 is active and is the first COM port at the moment (denoted by '[0]') 6 ) If the Processing sketch ran without displaying an error, press the stop button. 7 ) Hook up the arduino.

8 ) Run the Processing sketch again. When installing visual studio for mac what do you need for c++. 9 ) Check the console for active com ports; Serial list WARNING: RXTX Version mismatch Jar version = RXTX-2.2pre1 native lib Version = RXTX-2.2pre2 [0] 'COM3' [1] 'COM5' End of serial list 10 ) As you can see COM5 suddenly appeared in the list after we connected the arduino.

11 ) We now know that the arduino has COM5 and is the second COM port (denoted by '[1]') 12 ) We know adjust our code; Replace: arduino = new Serial(this, Serial.list()[?], 9600); // ATTENTION!!! With: arduino = new Serial(this, Serial.list()[1], 9600); // ATTENTION!!! 13 ) Save the program. 14 ) Load the arduino sketch unto the arduino.

15 ) Start the Processing sketch! Let your imagination run wild!

I put my arduino into an old printer adapter I found and I think it looks pretty good =) I did this by gutting the adapter and only saving the 'nipple'. I removed the 'nipple' from the cable by cutting into one side with a knife, after which the original cable could be pushed out and replaced by my USB cable. The adapter had a small hole (which I used for the usb cable) and a big hole which I used for the NES controller. The big hole however wasn't big enough so I cut some away with a saw (very sloppy) after which it was too big, I temporarily fixed this by putting some sticky tape around the controller plug. I've currently ordered a broke NES to harvest the controller port from in order to make it more. I currently don't have a camera at hand so here is a short desktopmovie of me bashing some buttons on the controls. If you get an error file saying java wasn't found you'll need to install it (again) In case anyone is wondering why I made a batch file; I was too lazy to reinstall java and made a small manual fix.

Btw, to play a NES game on your computer you will need an emulator: [windows] (If you're running vista, use FakeNes) [Mac] [Linux] And you will need some games(ROMS) ofcourse but these are illegal to download (Yes, even if you own the original) so whatever you do don't download them and especially not from this site because that one is the most illegal of all *GASP* Attachments •. More details Inside the NES controller is an 8bit shift register. By putting the latch pin high for a few microseconds I'm telling the chip to start spitting data at me. When it does this, the first byte becomes available to read over the serial pin.
