I have the following 2 components and a arduino Mega.
Pump: https://www.amazon.com/DC-12V-Brushless-Centrifugal-Submersible/dp/B00C6XNB50 (the pump here is 1.1a though) Relay: https://www.amazon.com/JBtek-Channel-Module-Arduino-Raspberry/dp/B00KTEN3TM
I was looking to turn on and off the pump at various intervals. Here is my progress:
Arduino - Relay: 5V - Vcc GND - GND pin7 - IN1
Relay - Pump: COM - Motor Adapter Live wire NO - Motor Live wire
Motor - Adapter: Motor -ve - Adapter -ve
I am not sure if I need a setup to prevent back emf and also, I am not sure how select and arrange those components (like while I may get solution for this here but where do I look up to calculate it other times)
I would appreciate any help in this matter. I have looked up but they are always for motors of similar but not same ratings, so I am a little worried to try.
My electronics skill is I know a bit of basics but I can follow instructions well. thanks.
