Experiment 6 Using OLED to Display 3-axis Acceleration Value

Share for us

Description: In this routine, we will let OLED dynamically display acceleration values from 3-axis acceleration sensor ADXL345 with dynamic graphical effects.


SunFounder Uno R3 * 1

0.96 Inch OLED * 1

ADXL345 * 1

USB Cable * 1

Jumper Wires


First, connect the circuit

                      SunFounder Uno                  ADXL345                OLED

                      5V ----------------------------------- +

                      GND --------------------------------- “-“ --------------------- GND

                      3.3V ----------------------------------------------------------- VCC

                      SCL ------------------------------------SCL-------------------- SCL

                      SDA ---------------------------------- SDA ------------------- SDA

Second, program (please go to our official website www.sunfounder.com to download the example code by clicking LEARN -> Get Tutorials)

Third, compile the program

Fourth, burn the program into SunFounder Uno R3 board

If everything goes well, you will see the OLED dynamically display the values of X, Y, Z axis measured by 3-axial acceleration sensor in real-time, the physical diagram is shown as figure 26:
