Very new at all this stuff and I’ve been trying to learn over the last couple weeks; and while I have come far; I am in need of your help…
How do I actually send my sensor data?
I have a Wireless Stick v3 with a sound sensor hooked up.
sound_analog = A4
sound_digital = 47
Basically when sound_digital goes to 1, I’d like the stick to wake up and send “Sound Sensor” or something…
I keep reading different things, but since I’m learning, I’m getting lost… Any input would help greatly! Sorry there is a bunch of extra stuff in this code, I’ve been trying all kinds of crazy things.
