Arduino Tutorial : Controling 4 relay module for use with a 5 volt water pump

In this video I used the following supplies to control a 4 relay module with a arduino
- Arduino uno
- Bread board
- 5-volt water pump
- jumper wires
- 1-4 relay module
- Fish tank tubing

The code is below

byte pump1 = 7;
byte pump2 = 10;
void setup() {
while (!Serial);
pinMode(pump1, OUTPUT); // variant low/high
digitalWrite(pump2, LOW); // variant input/output
}
void loop() {
digitalWrite(pump1, HIGH); // pump1 deactivated
//pinMode(pump2, INPUT); // pump2 deactivated
delay(2000);
digitalWrite(pump1, LOW); // pump1 activated
//pinMode(pump2, OUTPUT); // pump2 activated
delay(2000);
}

I thought it was and old video and disregarded it, turns out this was the best option. Thanks!

Thanks mate, your explanations has helped me clear my confusion on completing my project using 5v water pump.

[veervanshajwadehra]

thanks, bro i was frustrated but now my connection is done because of you
thanks, buddy

[yp]

Thank you so much!!! I was so frustrated because I couldn´t get the pump to work. A shame I can only give 1 like :/

[ShahrukhFakrudeenK]

This was exactly what I was looking for. Thank You!!!

[antonnipies]

thank you Sir! This video healped me a lot in my project!

[layton]

It needs a sensor to tell the archive the glass is empty so the pump turns off

[archietiongson]

Thanks bro.. I thought i need to buy battery to use my water pump

[joshuavillaver]

Thank you for sharing your knowledge, bro. This is a great help for my capstone project.

Ty so much this video solve my problem using water pump and relay

[cal]

nice ive always wanted to control water pumps

[cjdelphi]

You're using the 5v usb rail and when current gets drawn the relay drops out, the pump requires way more current than you're providing

[WithinandThroughout]

Don’t you have to have a kickback diode so to block against back emf to your Arduino? Anything when you break the magnetic field sends a electron dump from cathode to anode (+ to -)

[PakistanYouth]

how can we install ultra sonic sensor in it

[VortexGamer-oufn]

When would you use the “normally closed” vs “normally open”?

[AadeshKulkarni]

Hey, can I power the 5v relay from the main power supply instead of Arduino ? I'm new to this and don't want to burn down my house accidentally.

[josep]

Where would you add a separate power source(9v battery) for the pump? I'm making an alarm clock and will like to add the pump...

[ivndkoq]

Thanks!
Can you add the make and model of the pump?

[brandonly]

Hey, what is the model of water pump? And did those tubes come preinstalled on that pump? Or was that another diy thing you had to do?

[NickyAndre]

hello did you have the stl file of those pump black plastic?
