I2C Scanner - No devices found I connected an OLED display to SDA and SCL Pins of Arduino UNO. However, I cannot find the adress by using the Arduino I2C Scanner.
All of the wires are connected correctly and the display has power. What else could be the problem?
Edit:
Have you used the pull-up resistors SCL and SDA need to be pull uped using 5V. Try this and check if it is working have you connected SCL to A5 and SDA to A4
