graphic display on lcd

Hello I used a processing sketch that shows a graphic form of information recieved from a pulse sensor. I would like to take that information and display it on an lcd screen. I don't know how to take that data and send it out of processing and into the lcd, so I could really use some help! thanks

Paid LCD Project

Hello instructables, I have an idea for a device but not the skill to build a prototype.  I am in need of someone with technical skill in microcontrollers and LCDs. The device I aim to create is basically an LCD watch or bracelet. Rather than time which is numerical, I need the watch to display words. It will be wearable on the wrist and therefore use a battery. No buttons or input are required for this project. I also don't need to make the case. I just need the working parts. I envision that this will require an LCD screen, a microcontroller chip, memory, and a battery for power. If you are interested, I will be happy to pay you for your help. If interested, please PM me so we can discuss what I am trying to make further. I am flexible on the design and hopefully it would be a fun and easy project a willing participant.  Again, I will pay for your time and components but this should also be a relatively fun and straightforward project for anyone who's worked with LCDs (e.g Nokia screens) and microcontrollers before. I look forward to hearing from you.  Take care.

Arduino and scavenged LCDs

Hey guys i've recently received an Arduino Uno (tech-mas gifts !) and have started trying stuff out, i also had 2 old cellphones that i hadn't used for years, so i scavenged the vibrators and screens and left the rest untouched(no ripping appart, worry not) now i see that the screens both have a plastic thing with a lot if very tiny pins sticking out of them, and i wonder if there would be any way i can connect these to the arduino and use them as displays (was thinking of a smart-not-phone, wich does all the funny stuff a smartphone does without the phonecalls), please keep in mind i have a very basic set of tools (the arduino, a breadboard and the "starter pack"(with leds resistors ect...), plus a soldering iron, and would like to keep this project salvage based if possible (no money for smart-not-phones) info i could find on the displays: 1st one is a LMS240GF12,(non touchscreen) i couldnt find any info on this model but a few similar displays with lms241 or 242 names exist, so i guess the specs should be similar ? 2nd one is the touchscreen that came with a HTC Wildfire phone, and i think the display serial would be A3333 G8 but i'm not sure, none of the information is labelled and internet has been of little help as of now ^^. If you have any tips or need more info i'll be glad to receive them

broken lcd?

I'm building a little teleprompter, and I remembered my family had an old "broken" portable 7" dvd player. It turns out that just the little powerbrick was broken, BUT the display seems really washed out. Like, I hooked up an old Gamecube, and if you view it at an angle, you can see the little cube dancing around and everything, but if you look at it straight on (like most people), it's just a lot of bright white. Is it broken, or is there anything i can do to fix it? The color and brightness buttons do nothing.

Problem with LCD backlight

Hello everybody,  I'm here to ask a question I'm not able to solve on my own. I'm not good at programming, so it may be a silly question, but I can't find a solution. I'm building an Arduino based humidity and temperature monitoring system, with three DHT-11 sensors and a display to show readings from them. I'd like to be able to toggle LCD's backlight on with a pushbutton and have the code switch it off after a while. I can't  figure out how to make Arduino do it.

LCD Swappems

Hello creative tech people, This is my first post so I hope I got it in the right section, and I did a lot of research before creating this post. I've been researching this for a bit, and I've gotten a sudden fascination with LCDs (mostly of the full color display variety) and I've been planning on making  custom tablet style PCs based on old laptops just for fun and experimentation but in my planning I hit a bit of a snag in regards to the screen. Since much to my dismay they weren't swappable and relied on a controller intertwined in the motherboard. There's also the inverter which I'm not sure how relevant it is to the project, This is a real issue for me because I wanted to use a variety of screens from big ones to tiny ones from smartphones or mp3 players. I was wondering three things: 1. Can you make a monitor connect to a different motherboard through the magic of soldering? 2. (if #1 is a yes) will the controller handle the different signal or does each one have a different driver format and all that aggravating frippery? 3. Would taking apart a standard vga flat screen monitor and using that instead of a laptop screen avoid the issue altogether? Or would it bring up new problems?

Neotech NT7086 display and arduino?

I found a couple of these older looking dot matrix LCDs in some electronic logbooks that didnt work. it was a 14 pin connector, so i figured why not try it out. i found the pinout of each pin using the chips that were on board, but i don`t know where to go from here, or if i should even bother. the display was made by or for hantronix, and they have a touch layer that could be used as well. each display has 7 of the NT7086PQ chips on it, a 74HC74D, a 74HC40103D, and an LM324. it was originally connected via a flat flex cable, but it had a convenient place for headers to plug it into a breadboard. the 74HC40103D is an 8-bit synchronous binary down counter: http://www.nxp.com/documents/data_sheet/74HC40103.pdf the 74HC74D is a Dual D-type flip-flop: http://www.mouser.com/ds/2/302/74HC_HCT74-225071.pdf the Neotech chips are LCD display drivers: http://www.crystalfontz.com/controllers/NT7086.pdf upon inspecting the physical properties of the display I can see there are the rubber/carbon edge contacts on two sides and a ribbon on one end. The pinout i figured out is: 14 is GND 13 is base on SOT23 transistor     (connected to 12 on parent board) 12 collector on a SOT23 transistor 11 gets pulled low at some point (pulled low on parent board) 10 is power 9 is cl2          (unactive high?) (on one set of neotech chips, assuming the edge contact drivers) 8 Clock input (74HC40103D) 7 does nothing 6 is d4 on one chip? 5 is display off  (active low) 4 is d4 3 is d3 2 is d2 1 is d1 So i would appreciate any input people have. I would ideally like to drive this using an arduino/atmega, and although i have not read the neotech datasheet to much depth it would appear to work similar to the popular parallel displays, but maybe with different syntaxes. so is this a possible thing, or is it a fruitless endeavor? thanks in advance.

LCD Display, button and buzzer. Arduino?

This would be my first electronic project, and I'd like to get the advise of the instructables community. I want to build a gadget that when you press a button, a 2 digit number displays on one display (or one section of a display) and a countdown clock displays on another (or the other section of the 1st display). When the timer reaches 0, the buzzer goes off, or if the user pushes the button again, a new number is displayed and the countdown clock starts over. Seems pretty simple. I don't need a fancy display, probably a 4 bit clock radio type display. I would program the logic to display the number and how much time it will count down. Is an arduino the best application for this type of project? It seems a little overkill for what I'm trying to do, plus the cost of the arduino and parts would make making a bunch of these very expensive. If the arduino would be good for prototyping this, could it be made cheaper in a semi-mass produced fashion? Thanks for your help.

Toggling LCD Backlight with arduino ?

Hey, I'm working on a project where I need my LCD to toggle between On/Off.  By default, the LCD is OFF showing nothing. When button is pressed, LCD should be ON. When the button is pressed again, the LCD will display a “shutdown” warning message at which the user can confirm or cancel. Right now, I just need the ON/OFF function to work (without warning message). This is the code I have been trying, but it doesn't work properly. #include #include const int Temp = 0; const int Press = 1;      const int Noise = 2;          const int Settings = 3; const int ON_OFF = 8; const int LCD_LIGHT = A4; int buttonState0 = 0; int buttonState1 = 0; int buttonState2 = 0; int buttonState3 = 0; int buttonState4 = 0; bool isLcdOn = false; LiquidCrystal lcd(12, 11, 4, 5, 6, 7); void setup() {   Serial.begin(9600);   lcd.begin(16, 2);   lcd.noDisplay();   pinMode(Settings, INPUT);   pinMode(Temp, INPUT);   pinMode(Press, INPUT);   pinMode(Noise, INPUT);   pinMode(ON_OFF, INPUT);   pinMode (LCD_LIGHT, OUTPUT);     } void loop() {   buttonState4 = digitalRead(ON_OFF);   if (buttonState4 == LOW)   {     isLcdOn = !isLcdOn;     if(isLcdOn){       lcd.clear();       lcd.setCursor(4, 0);       lcd.print("WELCOME");       lcd.display();       digitalWrite(LCD_LIGHT, HIGH);           }   }     else{       lcd.noDisplay();       digitalWrite(LCD_LIGHT, LOW);     } delay(2000);   }

Where can I learn about display signals for color LCD screens such as these:?

I want to play with LCD screens on an Arduino, but I'm having trouble finding resources on generating display signals. I want to use color screens such as these:http://preview.tinyurl.com/c5n6ew?http://preview.tinyurl.com/d9d2vo?Or even regular LCDs such as these:http://preview.tinyurl.com/crm2wthttp://preview.tinyurl.com/2g5k24
