HI, i wanted to know how many Oled screens can be connect to Arduino uno, mega and nano individually ?
can i connect multiple displays to them or just one on each ? what is the maximum number of each type of LCD / OLED we can connect to each type of arduino board ? (uno, nano, Mega)
and how to connect multiple displays ?
i want to connect two to three displays to any one of them .
Please Help !!!
The number would depend on the type of display interface. It is a problem if the interface is I2C and the display address can't be changed.
Post links to the displays of interest.

If you are using I2C Oled displays then you can interface 3 OLED with Arduino Mega 2560. But it would be better if you use separate Arduino boards for each Oled. Using one Arduino will make the project too complex.
You can connect these Arduino boards with each other serially or can use a master Arduino board which will be controlling all these sub Arduino boards connected with OLEDs.
i connect two OLED to the board . 1 through the SPI communication and other with the i2c communication .it worked, thanks all
If you have several I2C OLED displays where the addresses can't be changed, you can bit bang I2C to use several at the same time.
