-// If you're using a GPS module:
-// Connect the GPS Power pin to 5V
-// Connect the GPS Ground pin to ground
-// If using software serial (sketch example default):
-//   Connect the GPS TX (transmit) pin to Digital 3
-//   Connect the GPS RX (receive) pin to Digital 2
-// If using hardware serial (e.g. Arduino Mega):
-//   Connect the GPS TX (transmit) pin to Arduino RX1, RX2 or RX3
