Sorry, i have tried searching, but looking for simple code to turn on and off the relays with "A" for on, "a" for off. 8 channels so, a thru h. have Total Control app and ATC lite, but the examples have inputs that i don't need, and can't get sketch to upload after i try to take the inputs out of the code. relay board does not have High/low designation. Bt06 bluetooth. thanks!
Sounds like you just need to know what to Google
and you might find the following background notes useful
Thank you Nick, that helps! i wasn't sure what to search for, and i am finding i am horrible with code :( i am able to connect with the bluetooth, but need to clean up the code so it is only the 8 functions on/off, no inputs.
