Driving OLEDs with Arduino

Figure 1 

The project illustrates how to display images on 4D OLEDs with the use of Arduino system.

The type of OLED used was µOLED-128-GMD which is a nice device for making 4D systems. The images are loaded on the SD card during the start of slide show for an OLED. This will serve as a test run to check if the images are stored on the card properly. A micro SD to USB adapter is required for the images to be written on the card then the SD card will be inserted in the OLED card slot. Both pins on the back should be ensured with jumper connection before powering with voltage ranging from 3.3V to 6V

The image on the display can be controlled using an Arduino and downloading the library with functions. This library is specifically written for MicroOLED-160-GMD1 module but will work fine with other modules. Doing this, the transmitter pin of OLED should be wired to the receiver pin of Arduino while the receiver pin of OLED should be connected to the transmitter pin of Arduino but with 1K Ohm resistor in between. The power and GND are wired from breadboard to Arduino.
