Arduino integration program

Hi. I've got queries about integration of program. I had done some simple program to test/check various modules (LEDs, push button, switch and etc.) functionality. However, i wanna type a program that if i press keypad '1', it will run the LEDs program to check to LEDs. If i press keypad '2', it will run the push button program to check the push button functionality. And so on for other programs. Anyone out there can help me? If possible type it out for me because i'm really not an Arduino expert. I will upload those simple programs to test/check the modules. So please help me out. Thanks alot !

Integrating Highschool Sciences

Irene Duke, Kate Hoff, Lyndsay Carlisle and myself are participating in the MIT course 11.124, _Introduction to Teaching and Learning Science and Mathematics_. We have a variety of teaching interests: Irene hopes to teach chemistry, Kate to teach Physics, myself Physics or Mathematics and Lyndsay hopes to teach social justice / political history. Provided Make magazines as inspiration, we were tasked to design a joint activity, merging four high school classes of these topics for a period of weeks or months. We developed the ideas described in this first entry over the course of a class period. Hopefully, we'll take the time to expand each step into an instructable, possibly including trials by fire teaching 8th-11th graders. The material is structured by conservation of energy and resources, inspired by the articles of Tim Andersen. The final demonstration we envision motivates the particular material we wanted from each field. A bicycle wheel is drives an alternator transforming mechanical energy into electrical. The electrical energy is used to run a electrolysis process, rendering separate measurable quantities of Hydrogen and Oxygen. The Hydrogen and Oxygen are then combusted for the students. The amount of mechanical energy can be measured, as can the electrical. The binding energy of H_2O can be used to determine the chemical potential energy rendered. Finally, the combustion both demonstrates the energy's new form, and the difficulties in storing energy. The difference between power and energy underlies all of these experiments. Conservation of linear momentumn should be a familiar topic with the students. Conservation of angular momentumn can easily be introduced at this point, demonstrated with the bicycle and a fly wheel. Chaning the orientation of the wheel can be exteremely difficult. For the chemical portion of the experiment, stoicheometry should be familiar to establish the link between the amount of gas generated and the energy invested. The most appropriate mathemetical tools are statistical. Sampling, linear regression and averaging would prove useful throughout the experiments. Global economic relationships leading up from the colonial period would perhaps be the most applicable topic form history or the social sciences. Though not a technical detail, an important aspect of executing such an idea involves the actual deployment of resources. Students could, for example be broken up by their topic of interest, whether it be the physical, chemical or social aspects of the project. Next, new groups would be formed with one or two members from each subject area. These groups could then attempt to execute the design from the first slide, or one which is similar. Throughout, the students will present their thoughts or understanding to the teacher. This design project should perhaps be phrased as simply turning mechanical energy into hydrogen. Students with social scientific background might be responsible for estimating the costs of the implementation in different settings, and that would be used to drive a larger scale version. So, before getting started on building and documenting this project, do people have suggestions? What worked to combine the physical sciences for you? What might have worked?

How to control Stepper Motor with Integrated Controller, with Arduino

I salvaged a few big stepper motors from a large Laser printer. Unfortunately they all have integrated controller boards. I would like to control them with an arduino. I am aware that an option is to remove the PCB then use a regular contoller. I would prefer to use the integrated board. The boards have the following inputs: 24V GND P/S LD CLK +5 GND The high and low voltage and ground are obvious. CLK is the clock speed (which I half understand). LD is Load?? P/S is pulse?? The board has an SLA6024 with a nice heatsink. (perhaps that helps. I am after a wiring diagram and arduino sketch to control the motor for a CNC machine. Your help is appreciated.

Batch check the integrity of AutoCAD? Answered

We need a way to batch check the integrity of a lot of AutoCAD files and need suggestions or recommendations.  These files have been recovered from a raw data image so many of them are corrupt and will not open.  The option to move any undamaged files would be extra beneficial. The only program I have been able to find is one called SmartPurger but it does not work as AutoCAD will popup with error messages on corrupted files and stall the process.  There is an option in SmartPurger to auto accept the popups but it does not seem to actually work.  Been Googling for a few hours and it looks like it somehow may be possible with LISP or Script programming but I've got zero experience with these things. Thanks!

IDEA - IRC integration in Instructables.com

I just had an amazing (i think) idea....Instructables should host an IRC channel.it would allow people to ask specific questions (often not necessary to archive) and chat without the necessary delay that a forum presents... the forum would still be the way to communicate with the group (whether they're online at the same time as you or not) but the IRC channel would allow for higher speed exchanges as well, thereby improving the ability to collaborate on projects, ask questions, and share insights.The IRC channel should be moderated, and public transcripts should be logged on the site in an openly accessible mannerThis allows others to benefit from previous topics breached in the channel, helps keep it clean, and provides a level of protection for children / young teens who use the site. The logs would be slightly behind the active chat (updated hourly) to discourage lurkers.The IRC channel's current viewers should be posted on the site, as well as an IRC protocol ink to the channel.that way, people can see what sort of activity is present on the server before joining.I believe Instructables has a lively enough membership to support such an endeavor, and that it would enrich the community, and bring us all much closer. I welcome anyone else's input on this idea, and hope the 'Ibles staff will take it under advisement.btw, I'd love a job... the bay area is much nicer than VT for the creatively minded

Power Surge Fried my Integrated Network Card?

At least, it seems this way. I while ago we had a weird "power surge like thing". It was odd... It seemed to "restart" some electronics...I was on my computer when It happened, it was like a really close lightning bolt. Though after it scared the crap out of me and I looked at my screen, the computer was still on and everything was running. Then windows started to act like I had just unplugged everything and plugged them back in. It started to read my flashdrive, my printer turned back on and announced the black ink was low (stupid $35+ ink :P), etc. Since it was going nowhere I just held the power button and shut er off. Then, later, after turning it all back on I found that it didn't have an internet connection. I finally got one after unplugging my router (Which I could still get a connection through the wifi) and connecting my modem to my comp through usb instead. I think it fried my NIC. ...crap Think that's what happened, and I'll have to buy a pci adapter instead? Thanks,RX --This is odd too. I went upstairs and my PSP, and Zune were both turned on.

Building Audio System, Have Questions About ICs? Answered

So as the title states I want to design an audio system, I purchased an old shortwave radio someone gutted, but the case is in great shape and looks really cool, would make a killer looking amp.  So a little background, I want to make a stereo amp I can hook up several inputs to and my speakers; likely a turntable, iPod, radio, and whatever else I feel like.  The radio came with a nice little 5 position rotary switch for that.  The main problem I am facing is what ICs I want to use, and what order.  I have not dealt much with audio and at first I thought of buying a radio and just putting the guts into this unit, but I thought this would be a good project to dive into audio work.  You can't learn if you don't push your bounds a bit, am I right? The first IC question is about chips like the PT2322.  There are several I have looked at that use a microcontroller for control, and I am not against using an Arduino Micro in this unit, but I am unsure of how the acknowledgment bit works.  The data input seems to just be a shift register, data gets clocked in, then latched.  Data is fed in in 8 bit strings, but then it mentions an acknowledgement bit as a 9th bit.  Is this bit for the latch, or is there a 9th bit fed in before everything is latched?  Should it be hi or lo?  As well I was looking at the commands, several commands have 7 of their 8 bits written as a *, does this mean that those bits can be set hi or lo?  I am sure these aren't difficult questions and I glossed over something important in one of the many data sheets, and that I do not use these chips with any regularity, if ever, doesn't help either!  But I like that these ICs all seem to have a 3 band tone control and volume control built into them. If I were not to use an IC controlled by a microcontroller, I am looking at using a BA3812 for the tone controls, 5 band is a little more then I need, I really only wanted 3, not 2 but not more then 3.  Bass, treble and mid range.  But I could not find a 3 band IC without microcontroller inputs required for operation, and it was not for the lack of trying.  I can handle 5 bands though, however I am wondering, should I go preamp to equalizer to the main amp, or where would I wire in the BA3812?  This seems like a stupid question to me, I feel like an audiophile is going to come along and say, "You never put the equalizer after the preamp, it always goes here or there!" or something along those lines.  As well, regardless of where its going to get wired in, since I am doing stereo not mono, I assume I will need 2 BA3812's, but the datasheet supplies a circuit for 3 Chips as well.  Which would be suggested, 2 or 3?  I am wanting to control both left and right tone controls together, so using 5 pots instead of 10, and would also like to be able to have a balance control.  I didn't see anything about balance control in the BA3812 datasheet, would there be a good way of accomplishing that with these ICs or the use of a couple op amps maybe?  I didn't really look into balance, I should have before asking questions. For the preamp the LM1036 seemed like a good choice.  I was reading into preamps, and they seem more important for the turntable then anything else.  The way the grooves on a record are cut they boost the high frequencies so they don't fade awayat lower volumes or something like that.  Because of that a preamp that boosts bass and cuts treble is useful and improves sound quality when using turntables.  Should I use a preamp only for the turntable input or for all inputs?  If I adjust the equalizer for records is a preamp necessary or should I use the preamp and set it with trim pots to boost bass and cut treble a little, or should it be fully adjustable as well? As far as what to use for the final amplification I am at a bit of a loss.  A home theater system I have is 1500W and is adequately loud, but the system I have for my turntable right now think is only 250W I believe and it seems louder.  Never really understood wattages for "loudness"  or output on sound system.  I saw an IC (can't remember number, its a TDA though) dual 50W amplifier.  Not sure if 50W for each channel would be enough.  Advice would be helpful. As a side note, if I do go the route of a microcontroller, I found this NJW1186 with stereo input and 5.1 surround output which I thought would be cool. I really appreciate any help. Thank you

Is it possible to operate an integrated home network from a laptop?

A couple days ago I was walking around my house with my laptop in hand, catching up on some American financial news via Russia Today. Needless to say I made it to the kitchen without any mishaps and brought everything into the dining room. As I was eating breakfast, I was staring out the window at my bird feeder, with the news going, when the idea hit me. I'd seen other instructibles on digital picture frames which use computers and essentially integrate them in the house in a unobtrusive manner. Why should I have to walk around with my laptop when, theoretically, I could have a network of computer stepping stones integrated throughout my house. Is it possible to program a thin network where all the clients mirror one laptop? Is is also possible to use Johnny Lee's infrared fingers to turn on/ control a digital picture frame thin client in places where you don't want to use a touch screen? ie. the kitchen, workshop, or even in a hospital?... Could all this be done economically by re-purposing used school/uni computers, and freeware like Linux and Ubuntu and Cloud One?
