Can you remake this for 4 pin ssd1306 or ssh1106 screens? thanks

What do you mean by 4 pins? Current ssd1306 is supported using SPI interface. Since no data is sent from the display to the mcu only 3 out of 4 pins are used.

Sorry for the late join, I only just found your project; I believe the query is for the I2C screens rather than SPI, there are two common types of ssd1306 screen available, one has 4 pins and is I2C (2 pins I2C plus 2 pins power/ground), the other does SPI and has 7 pins (not sure of the layout). Most arduino comments recommend the 4pin for I2C for simplicity, so if you have one of those on hand already you can't use it with an SPI-based code
