If you really want feeding to happen at the same time, you will need a RTC (Real Time Clock) module. There are other threads on this forum discussing that.

You can use ‘delay’ node to have the dispenser fire after X seconds, and repeat, but Arduino clock loops around every few days, and even without that, repeating every X seconds is likely to drift over time. The traffic light example [New guide article: Simple Traffic Light Example](https://forum.xod.io/t/new-guide-article-simple-traffic-light-example/186) will show you how to use delay and loops.

You will only need 2 of the 3 delay nodes from the traffic light example. The first is your delay between feedings, the second is to give the servo time to open, then restart loop. delay-ACT of 2nd delay node should feed an if-else-COND. if-else-T will be position of servo to dispense food. if-else-F will be position of servo between feedings. Output of if-else feeds to servo position pin.
