![]() ![]() Since the OLED display has no reset pin, therefore this -1 is used so that no pin Arduino would be utilized as the reset pin. Then, create an Adafruit_SSD1306 object display and send -1 to the constructor. Include those libraries along with the wire and SPI library for external communication.Download and install the Adafruit_GFX and Adafeuit_SSD1306 libraries.Turn on the circuit and observe the OLED display. Open the Arduino IDE and write the above-mentioned code. To Interface OLED Graphic Display Module with Arduino connect the circuit according to the given diagram. ![]() Moreover, the module has 1KB GDDRAM, which stands for graphic display data RAM, having 8 pages from 0 to 7, each has 128 columns, and each column can store 8 bits of data.ĭisplay.begin(SSD1306_SWITCHCAPVCC, 0x3C) ĭtTextColor(BLACK, WHITE) // 'inverted' textĭisplay.print("0x") display.print(0xFF, HEX) ĭisplay.startscrolldiagright(0x00, 0x07) The module operates from the voltage range of 1.65v to 3.3 V. Also, modules draw an average current of 20mA. Since the display requires no backlight, hence reduces the extra power requirement and cost. The OLED display modules come in different sizes and can be swappable. Certainly, 12C requires more input/output pins than 12C, but it is also faster. OLED module has the single-chip CMOS OLED driver SSD1306 which can interact and communicate with the microcontroller using a 12C or SPI interface. So, in this tutorial, we are going to interface ” OLED Graphic Display with Arduino UNO”. Hence, it also has better and improved image quality, lower power consumption, and better durability. ![]() Since, the display requires no backlight, therefore, more efficient than the simple LCD. Basically, OLED is a flat light-emitting technology made up of organic thin films between two conductors. Now, this time make your project a little entertaining, mesmerizing, and fascinating by using an Organic light-emitting diode, abbreviated as OLED. In most of the projects that need a display, you have used a simple LCD every time.
