duino - How to make this I2C OLED screen work? (probably
I have an Arduino Mega and would like to change the SDAA15. So that I can control an I2C LCD from there, I have the library but I don't see where the pins a. . .

Bei dem MEGA2560 R3 Microcontroller gibt es ftigt man eine Library welche noch nicht im Arduino Programm vorinstalliert ist. Wir verwenden in dieser Anleitung die „LiquidCrystal I2C“ Library.

Arduino Mega 2560 has onboard pull-up resistors. The Arduino Mega 2560 has 10k pull-up resistors on the SDA and SCL line to 5V. Therefore it is less compatible with a 3. 3V I2C bus. A level shifter is recommended for the Arduino Mega 2560 to protect 3. 3V sensors connected to the I2C bus.

Another illustration that demonstrate how to wire the i2c 162 LCD on ESP8266 12 Known as NodeMCU, as you can see the diagram below the SCL as Arduino Analog Pin A4 is connected to D1 on NodeMCU at the same time the D2 as the SDA represent as Analog Pin A5 on Arduino Board, As you may notice that the sketch code that we used it is not LUA script it is actually standard Arduino C compiled
How do you set other pins for SCL and SDA? - Arduino Forum
Parts you will need. The OLED Display; An Arduino, (Arduino Mega in this tutorial)Power source, Powerbank, Battery, or USB cable. Wires. The Circuit. The circuit is very simple. First, connect the GND with Arduino GND, VCC with 3. 3V or 5V on Arduino, SCL with SCL, and finally SDA with SDA pin.
Arduino Nano: I2C 2 X 16 LCD Display with Visuino
/6/2017A small oled screen and a rtc (real time clock) module which both use SDA,SCL,VCC,GND. VCC and GND isn't a problem, however SDA and SCL is. Using the adafruit gfx library there is no way to tell the arduino which pins to use.
