There are two kinds of 1.3” OLED that you’ll find:SPIandI2C. The SPI OLED has 7 pins while the I2C OLED has only four pins. This tutorial will primarily feature the I2C OLED because some users have trouble using it with non-Arduino boards. This is the front of the I2C OLED: The ...

Note that I used a 20 x 4 LCD display. If you have a different size LCD (16 x 2 is also common) you need to change line 20 toLiquidCrystal_I2C lcd(0x27,16,2);. If your LCD doesn’t have the default I2C address, 0x27, check out the complete I2C tutorial where I explain how...
