Arduino relays and pumps

Hello! I am new in using Arduino. I am having trouble solving a problem on my project. I want to test if I can control an industrial vacuum pump using an Arduino Uno board and use relay modules for the connection since the pump requires more input voltage than the Arduino. But I still am not sure if it'll work.
My project works in a way that if I press a button, the vacuum pump will suck in 5 seconds then stops. I am just not sure how to control the pump with Arduino without frying the components.

You need to share more information.

Show us a good schematic of your circuit.
Show us a good image of your ‘actual’ wiring.
Give links to components.

I think you have to design a millis()-based timer to do this job.

For an overview of relays see How to Add Relays to Arduino
for millis() timers see How to write Timers and Delays in Arduino
also checkout Multi-tasking in Arduino which will simplify things for you will need once you start using millis() timers

Oh Okay. Thank youuu. I'll be sure to add that here :slight_smile:

Thank you so much!

@jennicx, your topic has been moved to a more suitable location on the forum. Installation and Troubleshooting is not for problems with your project :wink:
