Uses a Circuit Playground board's built-in LEDs to diplay mood according to Galvanic Skin Response, Heartrate and Acceleration values.
The ChangeLog provides you with information about important changes.
The DevEnvironment explains setup of device during development.

Neopixel LEDs 0 and 9 on the Circuit Playground are used to indicate the current mood. Based on HFR, GSR and Accelleration values. Neopixel LEDs 1 to 8 are used to suggest interactions according to the currently detected emotion. The left PushButton (#4) is used to calculate a personal baseline. Start and Stop of calculation are indicated by a custom signal. Sensor values can be plotted during Development on the Serial Plotter if you set a flag to true.
- LED 0 and 9 indicate Emotion
- LED 1 to 8 indicate Interaction
- GsrSignal is a sliding average value over 10 seconds.
- Motion has to be present for a duration of at least 5 seconds in order to be detected.
- HFR value is correction factor for calculated EmotionLevel from GSR and Acceleration.
- Red LED indicates that HFR Signal was not found.
- Switch turns sound on and off ( mute when switch is on - side (right))
- LeftButton (#4) starts baseline calculation. Start and Stop indicated by custom signal. Any PushButton stops Calculation.
- Baseline is saved in EEPROM
