"No
trouble mate" - I've got it - it's working - from Android app, from command line, from crontab, browser, program. YaaaHooo! Thanks to the person(s) who did some earlier posting on this subject. Owe ya a beer. Thanks
Some of you will look at this and "not like my code" - then modify it. My end goal is to be able to take a standard electrical outlet box, a 110-usb module, this relay board, a duplex outlet and supplement/replace my X10 modules in my hydroponic greenhouse.
Now the STC15F104 (SOP8 = package type) chip works by sending 4 bytes to pin 6(?) saying +voltage on pin 7 or ground to pin 7. But that whole chip, 4k flash, 128 bytes ram .... I'm thinking there's got to be more than just "on"/"off". Status? Delay? There's prob 2 people in the world that know.
My testing: on, sleep 3, off, sleep 3 - works as expected. Changing sleep to 1 works, to .1 works to .01 not so much - think the .01 kinda out runs the relay.
Code: Select all/*
* This sketch demonstrates how to set up a simple HTTP-like server.
* The server communicates with the relay board via the Serial port
* http://server_ip/on will turn the relay on
* http://server_ip/off will turn the relay off
* There are no Serial.print lines of code
