Below is a code that is written to get pixels to blink to my heartbeat. Currently it beats green to my heart beat. How would I get this code to blink green for heartrates 0-90 and blink red for heartbeats 90-200? Using Arduino IDE, Adafruit Flora, and this link to help (https://learn.adafruit.com/heart-rate-badge/program-it)
