The OLED screen is a powerful tool at every stage of a project build:

• When prototyping, writing and troubleshooting code it allows easy visualization of sensor data.

• When designing a final build it can be used as part of the UI.

The OLED screen uses the I2C protocol (pronounced “I squared C”) which allows for the connection of multiple I2C compatible devices through the same port.

SAMPLE PROJECTS USING OLED SCREEN

Theodolite

A math teacher combined coding with geometry and used this Theodolite for students to map their campus taking measurements using the readings from the accelerometer. The simple code on this device shows the readings from the accelerometer (pitch and roll) as well as the data from the compass. Students would record the data they gathered then calculate distances manually. An extension of this project is to have the students program the device to calculate distances.

Visualizing Forces

The micro:bit and bit:booster were placed inside a ball that was swung like a pendulum. The OLED graphed the data from the accelerometer as the ball swung back and forth.
