lcd screen animation factory
This project focuses on the basics of animation using arduino and a 16 by 2 lcd. However this project can also be extended to lcds of other dimensions.
First we will start with the wiring of the lcd to the arduino, then with simple printing of a message to the lcd. Then we are going to move on to animation.
If lcd does not light up, check your soldering, wiring(recheck) and if it still does not light up it"s highly probable your lcd is corrupt, so you need to replace it.
After this upload sample code#include
If still nothing happens, do not lose hope, if you have seen the bottom row light up in the first part, it means that your lcd screen is OK. play around with the circuit and the soldering untill it works.
If you see the message "Working", then you have succesfully wired your lcd and finished the second part of this tutorial. Leave your circuit as it is, we will not mess with it anymore, all we have to do now will be in software.
This line declares an lcd object with interface pins as provided in the arguments. Now all your lcd interfacing will be done through this "lcd" object.( note that you can name this anything you want but maintain that name all throughout).
Well, we printed a message to the screen, but it isn"t very attractive to sit staring at that same message, moreover it does not serve any purpose. Thus we will in this section print a message which will scroll from right to left as in the advertisement boards. Only the setup() and loop() functions will differ, thus I"m showing only those functions, rest all remains same.void setup(){lcd.begin(16,2);}void loop(){int n;char message[]="scrolling text!";n=15;char* ptr=message;while(n!=-14){lcd.clear();lcd.setCursor(n,1);if(n<0){ptr++;}lcd.print(ptr);n--;delay(250);}}
Then we set a pointer ptr to hold address of message. This pointer value will be incremented in order to fit the message in the lcd window even after the characters slip out of view to the left. We do this for the left extremity and not for the right as the LiquidCrystal library can handle it for the right extremity(text scrolling out) but cannot handle negative column addresses as is required for our program.
Then we have a while loop which will display the message at various locations left to right thus giving the illusion that the text is moving. Note that the delay() at the end is to make sure that we can read the text and it does not whizz right to left at unreadable speeds. If the animation seems too slow or too fast, you can change th delay value.
For all the uses oflcd.print() function, we cannot display, say a dinosaur, in the lcd screen. However we can do this using a feature of the LiquidCrystal library called Custom Characters.
This is a custom character, which will display a dinosaur in the LCD screen. You can create your own characters here:https://maxpromer.github.io/LCD-Character-Creator/
After this we need to display them. However, these characters cannot be displayed using the normallcd.printmethod; we need to use this:void setup(){lcd.createChar(0,dino);lcd.begin(16,2);lcd.setCursor(0,1);lcd.write(byte(0));}
With this code, we create a custom addressable character out of our arlier defined dino[] byte. Our custom character"s address is given by lcd.createChar() method which defines character 0 as dino[]. We will then refer to this character as byte(0) which returns the address of our custom character, and finally print it on the screen using lcd.Write() method.
This program will finally teach you how to animate using lcd screens, read this carefully.#include
Here we use three custom characters to simulate an arrow. The rest is familiar to you. While running this on your lcd, you may notice a trail behind the arrowtail making it look longer than it is, do not woory, it is only the residue of the earlier arrow position.
That"s it! You have finished your first animation with Arduino and LCDs! Play around with the code, and combine this with button inputs to transform this into a full-fledged game!
This is actually an extension of the eariler arrows animation, thus I"m going to include only the parts which have changed.byte man[] = {B01110,B01110,B00100,B01110,B10101,B00100,B01010,B10001};void setup() {// set up the LCD"s number of columns and rows:lcd.createChar(0,arrowhead);lcd.createChar(1,arrowbody);lcd.createChar(2,arrowtail);lcd.createChar(3,man);lcd.begin(16, 2);attachInterrupt(0,buttonin,CHANGE);randomSeed(analogRead(A0));// Print a message to the LCD.//lcd.print("hello, world!");}int n;void loop() {// set the cursor to column 0, line 1// (note: line 1 is the second row, since counting begins with 0)://lcd.setCursor(0, 1);// print the number of seconds since reset://lcd.print(millis() / 1000);n=15;int rnd;rnd=random(15,25);while(n!=-1){lcd.clear();delay(10);drawman();lcd.setCursor(n,1);if(n==1){if(level==1){stopgame();continue;}}lcd.write(byte(0));lcd.write(byte(1));lcd.write(byte(2));lcd.setCursor(10,0);lcd.print(score);delay(100-rnd);n--;score++;if(level==0)score--;}}void drawman(){lcd.setCursor(1,level);lcd.write(byte(3));}void buttonin(){if(digitalRead(2)==LOW){level=0;}else{level=1;}}void stopgame(){lcd.clear();lcd.setCursor(0,0);lcd.print("Game over");lcd.setCursor(10,0);lcd.print(score);level=1;score=0;n=15;delay(3000);return;}

ESP chips can generate various kinds of timings that needed by common LCDs on the market, like SPI LCD, I80 LCD (a.k.a Intel 8080 parallel LCD), RGB/SRGB LCD, I2C LCD, etc. The esp_lcd component is officially to support those LCDs with a group of universal APIs across chips.
In esp_lcd, an LCD panel is represented by esp_lcd_panel_handle_t, which plays the role of an abstract frame buffer, regardless of the frame memory is allocated inside ESP chip or in external LCD controller. Based on the location of the frame buffer, the LCD panel allocation functions are mainly grouped into the following categories:
Drivers for some LCD and touch controllers are available in IDF Component Registry. The list of available and planned drivers with links is in this table.
Commands sent by this function are short, so they are sent using polling transactions. The function does not return before the command transfer is completed. If any queued transactions sent by esp_lcd_panel_io_tx_color() are still pending when this function is called, this function will wait until they are finished and the queue is empty before sending the command(s).

According to a report from Wisconsin’s Division of Executive Budget and Finance, not only has Foxconn not purchased any of the necessary manufacturing equipment to make LCDs, but it’s currently using the facility as storage. If manufacturing were to happen in the building, it would only be able to accommodate the final assembly of components—LCDs and other phone parts would be shipped to the facility and then assembled there.
In an interview with The Verge, Wisconsin Secretary of the Department of Administration Joel Brennan said that this industry was new to Wisconsin, and there was “justified criticism of the [former Governor Scott] Walker administration for entering into this contract.” No outside experts were consulted, and it appears there wasn’t any thorough discussion around how a contract like this would affect the community, nor if it was particularly viable considering LCD manufacturing wasn’t something that hadn’t really been explored in Wisconsin before.
TFT displays are full color LCDs providing bright, vivid colors with the ability to show quick animations, complex graphics, and custom fonts with different touchscreen options. Available in industry standard sizes and resolutions. These displays come as standard, premium MVA, sunlight readable, or IPS display types with a variety of interface options including HDMI, SPI and LVDS. Our line of TFT modules include a custom PCB that support HDMI interface, audio support or HMI solutions with on-board FTDI Embedded Video Engine (EVE2).
A small LCD screen can be extremely helpful with small microcontroller projects. Not everything needs to communicate to a fancy server using an ESP8266. However, if the simplicity of the character …
