Color and Frequency
The frequency of flash is calculated by the ratio of the current CPM value to the current CPM5 value. As the CPM value increases the frequency of the Neopixel flash increases.
The colour is based on the ratio of current CPM to the 5-minute average CPM5, giving a visual indication of how the radiation level is changing.
