kellybs1 11:45465d7cff1f 2 This program:
kellybs1 11:45465d7cff1f 3 - connects to a LoRaWAN by ABP/MANUAL
kellybs1 11:45465d7cff1f 4 - reads light data from an analogue Light Dependent Resistor
kellybs1 11:45465d7cff1f 5 - reads temperaure and humidity from a DHT22 sensor
kellybs1 11:45465d7cff1f 6 - sends the recorded data onto the LoRaWAN
kellybs1 11:45465d7cff1f 7 - sets the mDot to sleep
kellybs1 11:45465d7cff1f 8 - repeats these operations in a loop
