- Sayedur commented on Tarantula3's instructable OLED I2C Display Arduino/NodeMCU Tutorial
Really great post, although I couldn't get my display working with either of the Arduino Nano or NodeMCU. Just a question though: in step 8 your have described and shown in figure that OLED's VCC be connected to Arduino's 5V, but in the same fritzing wiring image you have actually connected to 3V3 of Arduino Nano (looks like one). I have read somewhere that this OLED has to be connected to 3v3, and not to 5V, can you please confirm that?
