Device for touching a touch screen? Answered

I need a type of solenoid/servo device capable of moving a few millimeters at a fast speed. I am building a device that will tap a touchscreen for me via an electric signal (In this case, and arduino.) they need to be relatively cheap and small. I will have four of them evenly spaced over four inches (They need to be no wider than an inch, would much prefer they be less than a half inch in width. Height isn't important, and length should also be under an inch.) They also need to be fairly weak, i dont want one of them punching a hole in my tablets screen by accident. Doesn't need to be controlled by PWM, either off (Not touching) or on (Touching) will work fine. Please do leave links along with the name of the device/part.

Drawing With A Touch-Screen?

My brother loves drawing and he has a friend who has something called a bamboo pad.  It doesn't have a screen which is why I found it questionable.  So we thought we might look for a touch screen he could use.  We had very little luck finding one that seemed like it fit the purpose.  Even those bamboo peoples' didn't look like they would do anything other than lines.  So we have a question.  Is it actually fairly easy to use a bamboo pad, and if not, what touch-screen could he use.

Touch screen Keyboard

Hey :) i have a sweet idea of building a touch screen keyboard that's separate from the monitor. i kno their are already some on the market but it be way cooler if i could build one myself. after doing some research i found the easiest way with the most versatility would be to have a touch screen ontop of a display and have the display then attached to a chip which would relay the image of the custom keyboard. the keyboard then would be hooked up to the computer and would function like a normal keyboard but soundless. :D the problem in all this planning is 1 i don't know how to put everything together, even though Ive been reading up , my knowledge of hardware design is minimal and 2 i don't know how to write programs, but if its any consolation im teaching my self simple programming like C++ but i doubt that will help. anyways , any suggestions Thanks a million Justin

Controlling a motor with a touch screen ?

So i am trying to control a motors speed using PWM (running through a transistor). I know how to make that happen but i am unsure how to use a touch screen to control the motor,  I have one of the test codes that is a touch pad 0-9 with enter and clear. I was wondering if there was a way that i can punch the number in push enter and have the motor run at that speed(starting with just 0-255) The touch screen is 3.2LCD TFT Touch Screen SD Reader http://www.ebay.com/itm/SainSmart-Mega2560-3-2-TFT-LCD-Shield-Touch-Screen-SD-Reader-4-Arduino-2560-/280930557613?pt=LH_DefaultDomain_0&hash;=item4168c41ead The code is // ITDB02_Touch_ButtonTest (C)2010 Henning Karlsen // web: http://www.henningkarlsen.com/electronics // Modified to work with UTFT on Mega w/Arduino 1.0.1 (C)2012 Otmar Ebenhoech, // // This program is a quick demo of how create and use buttons. // // This program requires the ITDB02_Graph library (8bit mode) // or ITDB02_Graph16 (16bit mode). // // It is assumed that the ITDB02 module is connected to a // ITDB02 Shield, a ITDB02 Mega Shield or that you know how // to change the pin numbers in the setup. // #include #include // Declare which fonts we will be using extern uint8_t BigFont[]; // Uncomment the next line for Arduino 2009/Uno //UTFT myGLCD(ITDB32S,19,18,17,16);   // Remember to change the model parameter to suit your display module! //ITDB02_Touch  myTouch(15,10,14,9,8); // Uncomment the next line for Arduino Mega UTFT myGLCD(ITDB32S,38,39,40,41);   // Remember to change the model parameter to suit your display module!

Hello, I'm currently trying to use a touchscreen that has 4 wires but 8 pins. I have a connector with 8 outputs, but I read some topics about touchscreens and everybody uses just 4 of them. So, right now, I'm using just 4 pins (It works with some noises) and my question is: If I use the 8 pins it will be better? If yes, how to connect them?

Want to find capacitive touch input for project

Hi there, I am working on a personal project and would like to find a capacitive touch input device which is roughly 5x30cm in size and will give me a x,y value for one or two fingers. The resolution does not need to be brilliant - 7 bit range in the x direction and maybe 5 bit in the y direction would be fine. Serial interface which I can use with my Arduino. I would also like to get a "pressure" for each - I know this is asking a lot but the "pressure" can roughly be guessed at not by actual pressure but by perhaps an increased/decreased capacitance or the amount of the surface being covered. I only need this to determine which of the two finger inputs is pressing hardest so again it doesn't need to be precise. Would anybody know of such a device? I mean - there must be companies producing these, I'd not want to go and have a custom one made for price considerations but surely there is something vaguely close. I have looked into the possibility of making one for myself but it appears I would struggle to do something this complex with my Arduino alone and the only IC which will do this with a homemade panel (not that I have the ability to create a capacitive panel with this many pads) seems to be QProx QT1081 which only accepts 8 inputs. Any pointers or ideas would be very gratefully received :) Cheers, Adam

Help with Arduino code. Works fine, then ignores parts of the code.

Alright, a bit of a complicated question, so bear with me (if you dare) __Purpose of project:__ Build a robot that solves the game "Fastest King" as fast as possible http://www.youtube.com/watch?v=GwGBUKCoIBs Here is a video of the game being played. The object is to clear the descending squares as fast as humanly (or robotically, in this case) possible. __Method of attack:__ -Four servos with attachments that allow interface with capacitve touch screens are positioned above each button -Four Photoresistors detect when a square is in the bottom position, ready to be pressed. -Potentiometer to control the speed of the arms and how fast they return to the "unpressed" position (denoted in the code by "d" or the delay in between the servo write commands) -On off switch, of course -All I/O is controlled by an arduino nano 328 IMAGES http://imgur.com/a/EprMu apologies for the terrible image quality, can update with better ones if necessary. (seems simple enough, right?) __Description of problem:__ Everything works swimmingly, except the game doesn't "remove" the square as soon as the correct button is pressed. this causes, when "d" is sufficiently low (100-75ms), the servos to press more than once for each square, causing mistakes within the game, slowing the overall time down. __Attempted fix:__ I attempted to implement some code that would cause each if statement checking for the square to also check that it hadn't pressed earlier within a certain time "doubletapdelay" effectively adding a delay in between doubletaps but leaving the rest of the servos free to activate. the odd thing is, the code i put in, (visible below, relevant parts bolded and commented) works well, but sometimes is completely ignored. even with the doubletap delay at 1000 ms while testing it, it would occasionally run as if it wasn't checking for double taps at all. If you think you can help out, or have a better idea for a way to do anything in this project, feel free to let me know. also, i can post any information you would like about this such as additional pictures or video, (though video is a bit difficult since my phone is inside of the machine whilst operating.

The angle would be easy, figuring the distance of the finger from the camera would be trickier... You might not get amazingly good resolution, but it should be enough for iPhone type scrolling sweeps and simple button pushing etc. Thoughts?

Make any monitor a touch screen!

Has anyone had any experience in taking a web cam, attaching it to the top of a monitor, then programming it to recognize face and hand movements, sort of how digital cameras today recognize faces, so it can be used to control a mouse. It would be sort of like having a virtual touch screen on any monitor and if someone could do this, I'd bet they'd make a lot of money.

Driving a Nook Simple Touch screen

Hello, I recently disassembled a Nook. I was going to fabricate a new case, root it and write a custom program, and present it as a prototype. However, the touch part of the touch screen no longer works. I have a few questions; answering any one of them will make me happy. 1) How can I hijack the touch interface? If I override the (broken) infrared touch input with a pen input, then that would be acceptable. However, I'm not sure whether the screen itself is broken, or if I broke something on the board from static discharge. 2) How can I troubleshoot and fix the touch interface? Speaks for itself. How can I get this working again? 3) Where can I find information on how to use this screen separately? My last option is to separate the screen and the touch completely, and build another tablet from scratch. Much appreciated! ~Ryan

LCD screen works from touch?

I was taking apart a small department store card reader and as i was doing so i noticed that the LCD screen would kinda  work from my fingers touching it.  Some parts of numbers and indicators glowed as I ran my fingers across it.  Is this from static electricity is my hands?  Or just residual power in the display.   All wires were removed from it so no capacitors to power it or anything.  I did notice that the silicon-rubber-carbon? thing on the top and bottom of it were attached.  Can someone with a knowledge of how these displays work please explain this phenomenon.

Pin-screen

Hi, I want to make a scanner, or maybe a "modeler". Background info keywords: https://www.youtube.com/watch?v=lvtfD_rJ2hE   <- NOTE THIS PROJECT IS WAY WAY MORE ADVANCED, I WANT A HIGHLY SIMPLIFIED VERSION OF THIS. https://www.physicsforums.com/proxy.php?image=http%3A%2F%2Fi.dailymail.co.uk%2Fi%2Fpix%2F2014%2F01%2F15%2Farticle-2539962-1AAFD4DD00000578-400_306x317.jpg&hash;=18c044d58272f31902c0c6194ba64eba   <- PICTURE OR JUST GOOGLE IMAGES:  PIN SCREEN Pin-screen. I want to make something that detects where each position is on a Z-axis (their x and y coordinates are fixed). So just a third number per-pin would allow me to map out the entire layout of the pins. I am not too sure if this has been done before or not. If anyone knows of a product that does this I would really appreciate more info. Anyways, THE ARDUINO PROJECT: - Something that takes feedback from each pin and maps it out in the computer. THE QUESTIONS: - How to read the feedback? (what sensor can I use, note that there will be hundreds of these sensors, so they have to be preferably small. Are there some very small linear position detectors? is an optical detector better? (I WOULD PREFER IT TO BE STURDY, i wanna play with it). Im thinking it should be something similar to how TVs work, with a pixel-matrix but instead this would be a matrix of position feedback, and I think it would be simpler than a TV since each channel only gives out 1 feedback (Z-position) instead of an RGB code (3 codes per pixel).  Anyone have some ideas on how to develop this project. Thank you!

Capacitive touchscreen - easy to hack via Arduino?

I have successfully hacked a 4-wire resistive touchscreen overlay, via Arduino, but the touch data is very noisy (mechanical not electronic noise). I'm considering a capacitive screen as a solution: are such screens hackable, using just an Arduino and basic circuit-building skills? Brendan

Changing old touch screen desktop into desktop monitor

So I have this seriously old touch screen desktop from FEC. I've been browsing around and found how to turn laptop LCD screens into monitors using controller boards, finding them by looking up the model number of the screen. I could probably use find the monitor stuff by myself, but when it comes to the touch screen interface, I'm clueless on what to look for. These are the pictures that I took of the boards and model numbers, and I'm assuming I would need something to either connect to the middle board, or something to replace it. I'm willing to take on the task, I just don't know entirely where to go from here as this is the first time I've really dug deep into something like this. The model number and barcodes are from the back of the monitor. At the end of the think white wire there are a ton of connections that go the the old motherboard of the computer. Is there anyone that might be able to give me a hand on what to find? Number on the large center board:............................RG9000PB0880   V1.0                              Below the number there is another number: 0821 Number for the small connector on the far right:.....RG9000PB0260 There's USB1 and AUDIO1 connectors on the large board in the center, and I'm assuming the long board at the bottom is power. mini-update: Could it also be possible to change the touch screen controller, run it into my computer via USB, and then find a controller for the LCD screen?

Arduino capacitive touch sensor help

So I have been messing around with the Arduino Capsense library with the immensely helpful guide; https://www.instructables.com/id/How-To-Use-Touch-Sensors-With-Arduino/  (many thanks to DangerousTim!)   using the code provided, i managed to get a relay to operate with a sensor.  It worked great and I was able to adjust the distance and sensitivity.  But when i tried adding another sensor and relay, it stopped working.  I've been trying to isolate the problem for a while now and have gotten nowhere.  I'm hoping someone can help me, here's the original code for the single sensor and relay; #include #include                                           //change '42' to any desired pin... long time = 0; int state = HIGH; boolean yes; boolean previous = false; int debounce = 200; CapacitiveSensor   cs_4_2 = CapacitiveSensor(4,2);  // To add more sensors... //CapacitiveSensor   cs_4_6 = CapacitiveSensor(4,6);        // 10M resistor between pins 4 & 6, pin 6 is sensor pin, add a wire and or foil //CapacitiveSensor   cs_4_8 = CapacitiveSensor(4,8);        // 10M resistor between pins 4 & 8, pin 8 is sensor pin, add a wire and or foil void setup()                    {    cs_4_2.set_CS_AutocaL_Millis(0xFFFFFFFF);    pinMode(13, OUTPUT);   } void loop()                    {     long total1 =  cs_4_2.capacitiveSensor(30);            if (total1 > 60){yes = true;}     else {yes = false;}            // to toggle the state of state         if(yes == true && previous  == false && millis() - time>debounce){              if(state == LOW){          state = HIGH; }     else state = LOW;     time = millis();     }                     digitalWrite(13, state);            previous = yes;                 delay(10); } and here's the code for the two sensors and relays #include int led = 13;     int led2 = 12;    long time = 0; int state = HIGH; long time2 = 0; int state2 = HIGH; boolean yes; boolean previous = false; boolean yes2; boolean previous2 = false; int debounce = 200; CapacitiveSensor   cs_4_2 = CapacitiveSensor(4,2);        // 10M resistor between pins 4 & 2, pin 2 is sensor pin, add a wire and or foil if desired CapacitiveSensor   cs_5_7 = CapacitiveSensor(4,6);        void setup()                    {    cs_4_2.set_CS_AutocaL_Millis(0xFFFFFFFF);    cs_5_7.set_CS_AutocaL_Millis(0xFFFFFFFF);  //Calibrate the sensor...    pinMode(led, OUTPUT);    pinMode(led2, OUTPUT); } void loop()                    {     int total1 =  cs_4_2.capacitiveSensor(30);     Serial.println(total1);     int total2 =  cs_5_7.capacitiveSensor(30);                     if (total1 > 60){yes = true;}     else {yes = false;}    if (total2 > 60){yes2 = true;}     else {yes2 = false;}           // to toggle the state of state     if(yes == true && previous  == false && millis() - time>debounce){                    if(state == LOW){          state = HIGH;        }        else          state = LOW;          time = millis();      }                          if(yes2 == true && previous2  == false && millis() - time2>debounce){                   if(state2 == LOW){          state2 = HIGH;        }        else          state2 = LOW;            time2 = millis();            }                 digitalWrite(led, state);       previous = yes;       digitalWrite(led2, state2);       previous2 = yes2;                  delay(10); } Any suggestions are always helpful.

Repurpose laptop to household touch screen calendar?

A few years ago I had come across instructions on how to repurpose an older laptop into a calendar for all in the household to use. The laptop would only run a calendar program (perhaps one or two more) where those in the house could post and update appointments or other commitments.  The original laptop screen was replaced by a touch screen while retaining a functioning keyboard.   I was certain that this had been an Instructable, but I have not found such a project on the site.  I have not found a hard copy in my file drawer or a soft copy on my backups.  Does such a project ring a bell to any of you?  If so, please let me know.
