Add to code below so specifications are met:

Frequency of Data: Readings must be taken once every 30 minutes, and the readings must be incrementally stored in a JSON file. To clarify, each reading must be added to a single JSON file so that a flat file of readings is stored over time.

Output Visual Using LEDs:

*Green LED lights up when the last conditions are: temperature > 60 and < 85, and humidity is < 80%

*Blue LED lights upwhen the last conditions are: temperature > 85 and < 95, and humidity is < 80%

*Red LED lights up when the last conditions are: temperature > 95

*Green and Blue LED light up when the last conditions are: humidity >80%
