Beginner Arduino Basic LCD + rotary encoders

New to Arduino, attempting to get basic programs working. Whats the best way to include multiple sensor readings to appear on a LCD Arduino screen for user feedback. So the sensor readout on the LCD would switch to the most recent change of rotation. Code to examine or help in the right direction would be appreciated. Thanks

sudden infant death syndrome, baby breath monitor

Hello everyone, I am a first year Mechatronics engineering student. Well, I don't know where to ask about such stuff, but my question is: As a new oncle, I see my brother & wife worried about the sudden infant death syndrome, so like the baby stop breathing when his sleeping, so like every time he coughs or so, they get really stressed. For such a reason, I want to develop for them a 'breath monitor system' For that, how shoud I proceed ? should I use pressure sensor under him, to know if he is breathing or not, then if he isn't, make an 'alarm signal' ? Or.. some t-shirt / 'chest wearable' he wear, to see if his chest is moving, or not ? is it simple enough that I can learn about arduino / sensors & do it alone ?  I had many questions.. hope I ll get some answers Many thanks !

After long time of searching, without success, i would like some help. I purchased one Sm-s4303r servo motor. My questions are: 1.How can i do it work for 3 seconds at normal speed and to stop it for example 12hours. To work 2 times per day. 2.What will be the suitable servo which can do 180° in every movement. I mean 180° now and the second (to complete the cycle 360) in 10 hours..

We are LIVE!!! - Knex Flux - General purpose Knex forum

Knex Flux is live now, you can visit it here: http://knexflux.net So, I randomly had that idea and Sandro likes it too and stuff, so yeah, is there any demand for a general-purpose knex forum uniting all the parts of the knex community under one hood? Of course such a forum would need people who actually use it, thus me asking if it would be used ^.^ I could do the hosting, I know my way around such stuff :) This would be in particular good for sharing progress, which isn't really possible on instructables, sharing small projects you don't think are worth a whole new instructable, helping others out and of course all just having a fun time together!

Anything but Knex...

I understand that knex are kinda cool and they have their place here on instructables. But to me it's getting kind of ridiculous. Just trying to browse through the instructables and find a useful one is pretty difficult now. I find a few useful ones here and there but in between them all are knex instructables. I think it's rather irritating to have to scroll past hundreds of instructables all for a different way to make a knex gun. Is there any way to browse with everything but the knex instructables? To be fair.. yes i'm exaggerating it's probably more like a 50/50 knex/non-knex ratio.

Structure advice needed for future teaching sessions of an AS child

Here is my dilema:  I haven't a lot to spend, nor do the parents of the child I am mentoring (Asperger's Syndrome).  Kits and puzzles are great, but can range in price from a few dollars to over $100 a PIECE.   I have been trying to go through Instructables and pick out "low cost", made from scratch, projects that would be suited for an 8 year old (soldering is out, but squshy circuits look good, etc), and would keep her engaged.   My biggest problem is not knowing "what" to look under.  I haven't a critiera idea on how to get to what I want quickly (I don't always have a LOT of time on line). I would like to make plans for at least 4-6 months ahead of time, so I can start on "putting together" what is needed for those projects. ANY suggestions will be helpful and I would be very grateful for any help in this matter.   Those experienced in teaching may have the best ideas, but all others are welcome too.  Out next session looms and the kit I got is a bit too advanced for the present situation;  so I am "projectless" other then a few small things like showing her how I made my Bristle Bot, and etc. So far, shes constructed 2 soda can bots,  a skeliton of a T.Rex excavated from a block of  P.O.P. (I think), a hex bot, a few T.Rex models, the Hadogenes Troglodyte puzzle her and I built,, a model of the solar system, etc and etc. She is going to be a real challange for me to find new and engaging things to create.....

Simple question 230v to 12v 50w/5a timed output

Hi, know a lil about electronics and electrical just want to make sure i'm not being a dummy or if there are any other better alternatives. Problem: A timed output circuit has gone bang on an piece of work equipment, wont go into detail as it may confuse the situation but it all works apart form the timed lamp button, I can see components on the lamp circuit disintegrated etc... So I wish to make the lamp part sort of stand alone. plan is to convert a 230v suply down to 12v 5a as the lamp it needs to power is 50w. Resolution: I was going to get this https://www.amazon.co.uk/200-250V-Halogen-Light-Electronic-Transformer/dp/B00CXK30UW and http://www.ebay.co.uk/itm/DC-5V-12V-24V-Infinite-Loop-Cycle-Timing-Timer-Time-Delay-Relay-ON-OFF-Module-/192106941494 Build accordingly and place in a project box with a push button on the project box also. Can anyone see any issues with this?

Advanced Helmet

Advanced Helmet By: Arseny Ratnikov I want to create a helmet that looks like a sci fi helmet (mass effect, titanfall, halo, etc.) and that; **Want to make cool helmet, need help with having multiple camera feed output to multiple screens** * Protects my head (able to decrease force from impact by significant degree) * Can filter the air I breath (does not need to be super extreme filter, just filter out general junk, the better the filter the more pleased I am, but if it becomes too bulky/expensive then it is unnecessary)(Optional/Most Likely) * Has a HUD with my vitals on it. I would wear some sensors, such as HR monitor to have some cool biofeedback, maybe also include other information.(option) * Maybe even have it be a digital display where there are cameras on the front and maye back of the helmet that then are displayed on the interior screen, where I have voice commands setup for some different things. * Have the helmet be as sound proof as possible and have microphones where my ears would be, then inside the helmet speakers, so that I can modify the noise around me to be how I want it to be. I understand this would be rather difficult (at least including all of the bullets) and that it could even be a touch silly. Yet, I find this a rather intriguing pursuit and think it will help contribute to becoming a cyborg. Any tips would be greatly appreciated as I don't really know where to start for this. I can imagine a lot of the work might be done on an arduino, but I simply don't know the feasibility of modifying noises of the world around you and having the cameras on the helmet. So here's a little prioritization sheet I worked out, it is not exactly in order, and maybe you all have some suggestions on what might be more critical to design and functionality. Prioritization 1. Functionality a. Head protection a1. Padding/Inertia dampener a2. Sturdy/solid b. Control of phone through bluetooth b1. In helmet speakers b2. In helmet microphone b3. Voice control c. Control of other systems such as screens c1. Voice control of screens c2. Screen modification c3. Screen HUD and other functions (maybe GPS map, time, etc.) d. Camera view d1. Camera live to screen with little to no latency d1a. 360 degree view compressed to 180 degree screen (maybe) d2. Computer control of camera feed d2a. Visuals, different HUDs e. Sound modulation e1. Sound cancelling e2. Sound reproduction at low to no latency e3. Sound modification e3a. Changing pitch e3b. Change decibel levels e3c. Change relative level of external sounds f. The HUD f1. Display of vitals f1a. Heart rate, oxygenation, etc. (Requires some monitor) f2. Display of time and other running interests f3. Display of current location on google maps/GPS system g. Air Filtration g1. Filtration of air, relatively high quality g2. Seal on head or seal over mouth and nose or full body suit that connects to helmet h. Extra Features 2. Style a. Look good b. Look like popular sci-fi media c. Does not interfere with functionality and accents functionality How should I do this? I am planning on using some old phone screens if I can for the screen part and multiple cameras. I plan on using a raspberry computing system (might need multiple) to modulate the output from the cameras. How could I make multiple camera outputs lay onto multiple screens that looks good at three to five inches from the eyes? Also how can I make the raspberry pi control my phone and computer via voice, or at least change a screens properties? Thanks
