Can I use a relay with a single Servo Motor?

Hello there Arduino people!

I’ve been planning on doing an Arduino school project for the first time, I’ve been learning and gathering information for a while now, my project, in a nutshell, is an auto plant watering robot it simply sprays water at a specific time each day, I’m planning on using a 9G Micro Servo and I wanted to use a relay to control when the electricity flows through the circuit, I actually don’t know if I need it, you gotta know that this is all new to me and I don’t want to burn or damage any parts.

if you have any advice or tip please let me know

What does the servo do?

Yes, an Arduino can control a relay (using one pin) and a hobby servo (also using one pin). Why would you think that it couldn't?

Use digitalWrite() for the relay pin and the Servo library for the servo pin.

Note: Most relay modules sold for use with Arduino are "active low". Setting the output pin LOW activates the relay coil. Setting it HIGH deactivates the coil.

it moves I wire which's connected to the water sprayer
