Introduction
In this article,we propose an overview of the Adafruit Circuit Playground Express (CPX) built-in sensors. This aim of this page is to show you how to leverage them in MakeCode. So, if you are not familiar with MakeCode, we advise to have a look on MakeCode page in this wiki.
In MakeCode, there are two means to read the code : through events or by reading live data:
- Events: code runs when an event is detected. For example, the
On shakeevent runs code when a certain type of shaking is detected by the accelerometer. - Live data: live reading of the sensor data without a particular event taking place. For example,
Rotationgets a immediate reading from the accelerometer.
You will find below the 2 style of programming with sensors : through events (left picture) and through live data (right picture).
Adafruit Capacitive touch
On the CPX, there are 7 capacitive pins (A1, A2, A3, A4, A5, A6 and A7). They can be used as buttons (like buttons A or B). There are two means to read the
