Hi! You can make it using a method very simple. Add in ferduino tab: unsigned long interval_feed_millis = 0; int interval_feed = 10; // in minutes boolean feed_mode = false; Add on loop: if(feed_mode == true) { if((millis() - interval_feed_millis) > (interval_feed*60000)) { feed_mode = false; ler_ti...

If you put 3V on PCF8575 the output voltage will be 3V probably. 3V can be insufficient to activate some relays. ...
