The display is connected by utilizing the i. Which pins to use for this differs on some arduino models, but on the UNO and NANO you use pin A4 SDA and A5 SCL. If youre using another arduino, google the pinout and look for SDA and SCL pins. For example, google arduino mega pinout, and check the images. I first attempted to power my display from my arduinos 5v. This worked, but only halfway the display fired up, and started cycling the demos in the sketch we will see later on, and then froze after a few seconds. I then powered my display from my external 5v supply with common ground to the arduino, which did the trick the display is now working properly. The connections from the display VCC to external 5v. This looks like itll be quite useful though a write function that doesnt take a registerAddress might be nice. Exorcism Encounters With The Paranormal And The Occult Pdf S here.
