Check your display to make sure that it is the same as the image below. The first and most important thing to note is that some of the displays may have the GND and VCC power pins swapped around. How to connect the Geekcreit 0.96 Inch 4 pin white I2C OLED module to Arduino How to Connect the Geekcreit 0.96 Inch I2C OLED Display to Arduino These libraries are installed in this tutorial. Libraries are available that make it easy to start using the display right away to display text and graphics. This interface is sometimes called TWI (Two Wire Interface).Īt the very lowest level, the Arduino Wire library is used to communicate with the display.

The data connection is I2C (I☬, IIC or Inter-Integrated Circuit). The display connects to Arduino using only four wires – two for power and two for data, making the wiring very simple.

Libraries are then installed and some example programs run which show how to use the display in an Arduino sketch. The function I'm using is as follows.In this tutorial a 0.96 inch monochrome OLED display from Geekcreit is connected or interfaced to an Arduino. However when the headingFiltered variable is at 359 and the car turns to Zero,the headingFiltered becomes to 0 via all the values between 0 and 360 rather than just becoming 0.This causes my car be constantly steering side to side when heading in this relevant direction.Īlso if there is anyway that this function could be improved,I'm open to suggestions.

I am using the HMC-5983 magnetometer module to obtain the compass heading of a autonomous car I am building using the arduino platform.I'musing the
