# Purpose
# - transmit the following to RPI4 using binary:
#   - CPU temps (low <30°; medium 30°<x<45°; high 45°<x<60°; panic >60°)

# - receive the following from Arduino using binary:
#   - used current of RPI 4
#   - used current of RPI 1.2
#   - uptime
#   - cpu usage (core #0 - #3)
#   - cpu frequency
#   - cpu temps (RPI 4)
#   - ram usage
#   - am capacity
#   - swap usuage
#   - disk usage
#   - disk capacity
#   - disk used
