Design with Mono 0.96in 128x64 OLED with STEMMA QT in Cirkit DesignerThe Mono 0.96in 128x64 OLED with STEMMA QT is a compact display module featuring a high-contrast, monochrome OLED screen. With a resolution of 128x64 pixels, this display is capable of presenting text, graphics, and animations with clarity. The inclusion of the STEMMA QT connector simplifies interfacing with microcontrollers, such as the Arduino UNO, allowing for quick and easy prototyping. Common applications include wearable devices, user interfaces, and any project where visual output is required in a small form factor.
This circuit consists of an Arduino 101 microcontroller connected to a 0.96" OLED display via I2C communication. The Arduino runs a program that initializes the OLED and continuously displays an animated sequence of frames on the screen.

This circuit features an Arduino UNO microcontroller connected to an OLED 128x64 I2C Monochrome Display for visual output and two pushbuttons for user input. The Arduino runs a Pong game, with the display showing the game and the pushbuttons used to control the paddle movement. The display is interfaced via I2C (SCL and SDA), and the pushbuttons are connected to digital pins D2 and D3 for input detection.

Q: Can I use this display with a 5V microcontroller? A: Yes, but ensure that the I2C lines are level-shifted to be compatible with the display's logic level.
Q: How can I change the I2C address? A: The I2C address can be changed by altering the address jumpers on the back of the display module. Refer to the module's datasheet for details.
Q: What library should I use for this display? A: The Adafruit_SSD1306 library is recommended for use with this display and can be installed via the Arduino Library Manager.
