Installation

1. Click on the Clone or download button and select Download ZIP. The file will download as D1M-WX1-APRS-ThingSpeak-master.zip.
2. Unzip the file. The unzipped folder will contain a LICENSE and README.md file and a folder D1M-WX1-APRS-ThingSpeak. Copy this folder to your Arduino sketchbook folder. If you need to find your sketchbook folder, open the Arduino IDE and use menu File | Preferences. The first line tells you where the sketchbook resides on your computer.

Add these Libraries to the Arduino IDE:

• BME280 by Tyler Glenn https://github.com/finitespace/BME280 - download as zip and use menu Sketch | Include Library | Add .ZIP...
• hp_BH1750 by Stefan Armborst - use menu Sketch | Include Libraries | Manage Libraries... and search for hp_BH1750. The reference for this excellent, but complicated, library is at https://github.com/Starmbi/hp_BH1750
