Submersible Pump with an Arduino and relay and Arduino

I purchased from Sparkfun:

  1. Arduino Uno

  2. SparkFun Qwiic Single Relay

  3. Wall Adapter Power Supply - 9VDC, 650mA (Barrel Jack)

  4. Amphibious Horizontal Submersible Pump

However, I am not sure if the Arduino with the wall adapter can power the pump. How can I get help?

Thanks

You can power up the Arduino with the 9V wall adapter. The pump you’ve chosen runs at 3-6V DC. You have to connect the Arduino’s 5V pin to the NO terminal of the relay. And positive terminal of the motor has to be connected to COM. Thus, when you switch on the relay, NO and COM will be shorted and the motor will start running.

By the way, since you’re not using a QWIIC board, you could choose a simple 1 channel relay. The coding part could be easier and you could save more money. However, your chosen relay board will solve your purpose no doubt.
