MATEOEMILIO:
Starting code of CrazyVito1. - Album on Imgur I've do it and the red led's of the arduino had blinked, then i've tryied with the code of the OLED and nothing goes on working on the screen nor nothing appears on it.
The code doesn't display anything on the display, it only scans the I2C bus for devices.
You need to run the code with the serial monitor open, it shows the devices it found there (unless you connected it wrong).
I first just want to make sure the display is available on the bus before we try anything else, so run the code and post what it says inside the serial monitor
