hi guys i need help for some edit to my sketch
I need show word (HOW)on display with the first click on the button , with the next click on the key of the word (ARE)with the next click (YOU)will be displayed with the next click (TODAY) and with the next click this cycle will start again from (HOW)
any one can help me for add this 4 word Separately in my sketch?
this is my sketch
thanks
#include <Adafruit_GFX.h>
#include <gfxfont.h>
#include <Adafruit_SSD1306.h>
const byte buttonpin = 8;
const byte OLED_RESET = 4; // not used / nicht genutzt bei diesem Display
Adafruit_SSD1306 display(OLED_RESET);
void setup()
{
pinMode(13, OUTPUT);
pinMode(buttonpin, INPUT_PULLUP);
// initialize with the I2C addr 0x3C / mit I2C-Adresse 0x3c initialisieren
display.begin(SSD1306_SWITCHCAPVCC, 0x3c);
Serial.begin(9600);
display.clearDisplay();
display.display();
delay(2000);
display.clearDisplay();
display.setTextColor(INVERSE);
}
void loop()
{
if (digitalRead(buttonpin) == LOW)
{
display.clearDisplay();
display.setCursor(41,20);
display.setTextSize(1);
display.print("");
display.setCursor(32,20);
display.setTextSize(0);
display.print("HOW ARE YOU TODAY");
}
else
{
display.clearDisplay();
}
display.display();
}
Take a look at the StateChangeDetection example in the IDE. It will show you how to detect when a button becomes pressed which allows a variable to be incremented each time
Use the value of the variable to control what is printed. For bonus points put the text in an array and use the button press counter as an index to the array of words thus making the code much shorter
I could, but I am not going to. You will learn more by doing it yourself
read the button input
has it changed since last time ?
if it has changed is the button now pressed ?
if yes then it has become pressed so increment a counter and take action based on its value
save the current state as the previous state ready for the next test
keep going round this loop
I searched a lot on the net but did not find the right result
If anyone can please take a look at my sketch and modify it
So I can use it as an example
thanks
Start with the example I pointed you to. The value of buttonPushCounter is printed each time it is incremented.
If ithe value is 1 output word 1, if it is 2 then output word 2 etc
i put full my effort but i cant be successfull
i have 4 kinds of mode in my project
i want showing the word mode1 at the first on display without press any button
by pressing buttonPin = 8; mode 1 replace to mode 2 and by clicking again change to mode 3 and 4 and by clicking again turn back to mode 1
please edit my sKetch I am not very familiar with arduino coding
thanks
this is my scetch
#include <Adafruit_GFX.h>
#include <gfxfont.h>
#include <Adafruit_SH1106.h>
const int buttonPin = 8; // the pin that the pushbutton is attached to
const int ledPin = 13; // the pin that the LED is attached to
// Variables will change:
int buttonPushCounter = 0; // counter for the number of button presses
int buttonState = 0; // current state of the button
int lastButtonState = 4; // previous state of the button
const byte OLED_RESET = 4; // not used / nicht genutzt bei diesem Display
Adafruit_SH1106 display(OLED_RESET);
void setup() {
pinMode(buttonPin, INPUT);
pinMode(ledPin, OUTPUT);
display.begin(SH1106_SWITCHCAPVCC, 0x3c);
Serial.begin(9600);
display.clearDisplay();
display.display();
delay(2000);
display.clearDisplay();
display.setTextColor(INVERSE);
}
void loop() {
// read the pushbutton input pin:
buttonState = digitalRead(buttonPin);
// compare the buttonState to its previous state
if (buttonState != lastButtonState) {
// if the state has changed, increment the counter
if (buttonPushCounter == 1) {
buttonPushCounter++;
{
display.clearDisplay();
display.setCursor(32,20);
display.setTextSize(0);
display.print("MODE1");
}
} else {
}
// Delay a little bit to avoid bouncing
delay(50);
}
// save the current state as the last state, for next time through the loop
lastButtonState = buttonState;
// turns on the LED every four button pushes by checking the modulo of the
// button push counter. the modulo function gives you the remainder of the
// division of two numbers:
if (buttonPushCounter % 4 == 0) {
digitalWrite(ledPin, HIGH);
} else {
digitalWrite(ledPin, LOW);
}
}
No .Mode 1 is displayed on the screen SH1106 without hitting any key. With the first click, Mode 1 is deleted and Mode 2 is displayed. With the next click, Mode 2 is deleted and Mode 3 is displayed. With the next click, Mode 3 is deleted and Mode 4 is displayed. with the next click,again Mode 1 is displayed in sh1106. And this cycle continues
Unfortunately, I do not know much about Ardiono coding
And I could only write code here
#include <SPI.h>
#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>
#define SCREEN_WIDTH 128 // OLED display width, in pixels
#define SCREEN_HEIGHT 32 // OLED display height, in pixels
// this constant won't change:
const int buttonPin = 2; // the pin that the pushbutton is attached to
const int ledPin = 13; // the pin that the LED is attached to
const byte OLED_RESET = 4; // not used / nicht genutzt bei diesem Display
Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);
// Variables will change:
int buttonPushCounter = 0; // counter for the number of button presses
int buttonState = 0; // current state of the button
int lastButtonState = 0; // previous state of the button
void setup() {
// initialize the button pin as a input:
pinMode(buttonPin, INPUT);
// initialize the LED as an output:
pinMode(ledPin, OUTPUT);
display.begin(SSD1306_SWITCHCAPVCC, 0x3C); //Start the OLED display
display.clearDisplay();
display.display();
display.setTextSize(2);
display.setTextColor(WHITE);
display.setCursor(30,0);
display.println("WELCOME");
display.display();
}
void loop() {
}
You have a sketch that prints the value of the button press counter and you have a section of code that tests the value and if it equals 1 then it prints "MODE1"
Add more tests and for each value of the button press counter print what you want for that value
