I want to send wav file stored in a SDcard to thingspeak using electron.
I am able to send sensor data to thingspeak, but don’t know how to send file from sdcard. Can you provide me helping example or link?
What have you tried so far, and where did you get stuck?
ThingSpeak stores numbers. Up to 8 Fields per channel.
Getting that to work with a .Wav file will be interesting.
