Download i2c library for arduino pdf converter
Follow the next steps to install those libraries.
In the loop() is where we read the sensor and display the temperature and humidity on the display.

LCD Display I2C Adapter for Arduino With PCF8574A: 6 Steps.
Please make sure that you have the SDA and SCL pins of the OLED display wired correctly.
Address 0x3D for 128x64.
The OLED display provides an easy and inexpensive way to display text or graphics using an Arduino.
The examples in the library are too advanced to grasp.
The code starts by including the necessary libraries.
It is too advanced for me right now, I keep it for when the time is right.
Thank you for sharing your time and knowledge with us.
That file contains the C array for the image.
Additionally, many of these modules already come with an internal pull up resistor, so you don't need to add one to the circuit.
DHT22 Humidity and Temperature Sensor With Arduino.
For example, if you have an LCD with 20 columns and 4 rows (20x4) you will have to change this to lcd.
Restart your Arduino IDE.
The Adafruit OLED library provides useful methods to draw pixels, lines and shapes.

For this project you also need two aditional libraries to read from the DHT sensor: the DHT library and the Adafruit_Sensor library.
The Library Manager should open.
Thanks for reading Steve.
Thanks for the projects!
IDK for how long.
The Adafruit_Sensor and the DHT libraries are used to interface with the DHT22 or DHT11 sensors.
Declaration for an SSD1306 display connected to I2C (SDA, SCL pins).
Arduino board (Uno or Mega).
Note: if you're using a module with a DHT sensor, it normally comes with only three pins.
Thanks for the guide.
For example, try to change message on first and second row.
Then, use a Image to C Array converter to convert the image into an array.
With I2C module you will be able to connect the LCD with Arduino board with only two cables!
Search box and install the DHT library from Adafruit.
In the setup(), initialize the serial monitor for debugging purposes.
I2C scanner sketch to find your OLED address.
Some of I2C LCD interfaces have pins (or solder pads) that can be changed to change the address.
Then, use the write() method to display your chosen character.
The (x1, y1) coordinates indicate the start of the line, and the (x2, y2) coordinates indicates where the line ends.

Thanks for your feedback Menel!
If you have an LCD 20x4 and you want to print a message to column five and third row you have to use: lcd.
After wiring the circuit and uploading the code, the OLED display shows the temperature and humidity readings.
You can find the I2C scanner sketch here.
Display Temperature and Humidity in the OLED Display with Arduino.
Thanks for the free Downloads.
Add a 220Ohm resistor in series with each column to avoid possible shorts between a HIGH and a LOW line when pushing multiple keys at a time.
LCD display with Arduino uno.
Wire scan in the constructor to get the device addresses dynamically and has methods that handle writing to each I2C OLED.
OLED display simple even for me.
Pass true as argument to invert the colors of the screen or false to get back to the original colors.
The i2c module has a built in potentiometer for contrast adjustment.
How to read Keypad with Arduino and I2C.
After installing all the necessary libraries, you can upload the following code.
Pause for 2 seconds.
For example, for 16 columns display max length is equal with 16 and for 20 columns display max length is equal with 20.
Excuse me, where can i get the libraries for the OLED display?
The I2C address for the OLED display we are using is 0x3C.
Download the code from here and open it with Arduino IDE.
