Oled i2c Display Interfacing with Arduino Uno Circuit Diagram:Īs you can see the circuit diagram is really simple. So, now let’s have a look at the circuit diagram. But there are situations when both the i2c addresses are not working, so when you end up in a situation like this, then you will need to use the i2c scanner, which I will explain in the programming section. But if you remove this resistor and solder it on the other side then the i2c address will become 0x7A. This small resistor is the i2c address selector. This display Module has a total of 4 male headers which are clearly labeled as VCC, GND, SCL, and SDA. This Oled display module can be powered up using 3.3 to 5 volts due to which it can be easily used with 3.3 volts supported controller boards like Nodemcu ESP8266, ESP32, etc and 5 volts supported controller boards like Arduino Uno, Arduino Mega, Arduino Nano and so on. But in this tutorial I will only focus on the Oled display modules that support i2c communication. There are other types of the Oled display modules, which are available in different shapes and sizes, some are using i2c communication protocol, there are also other Oled displays that support the SPI communication. Unlike the 16×2 liquid crystal display module, the Oled display does not require backlight, which results in a very nice contrast and moreover the Oled display consumes less power when compared with other displays.

Which I will tell you in a minute how to find this. Only by looking at the Oled display it’s really hard to tell whether this is SSD1306 or SH1106 model. There are two different models of the same Oled display module which are SSD1306 and SH1106. OLED stands for Organic light emitting diode.
This is a monocolor, 0.96-inch with 128×64 pixels Oled i2c display module. The Oled displays are the kinds of devices you’ll see on items like mp3 radios and smart watches and they’re very nice These things have a lot of excellent properties to use with an Arduino as a display, they are very easy to read, they take a very small current and you can read them from different angles. Screen, but very small one as you can see in the picture below.

These were developed during the 20th century the very first commercial device to use old LEDs was a Kodak camera in 2003 in 2013 Samsung became the first company to release OLED televisions and they’re now the biggest manufacturer in the world of OLED television screens now, the Oled we’re going to be using is not as big as TV I would appreciate your support in this way! Oled Technology: I may make a commission if you buy the components through these links. Note: For step by step explanation and practical demonstration, watch the video given at the end of this article. Without any further delay let’s get started!!!
