I bought a pump (Anself brushless DC Pump DC5V 2.3W) with USB-Male-connection to get power. It runs, if connected to any USB-Port. I'd like to turn the pump on and off with arduino UNO. But how can I connect Arduino UNO with the Pump?
Do you know how much current the pump requires? You can buy USB to screw terminal adapters but Arduino can only control a pump, not power it.
EDIT: Oops, just noticed power is 2.3W or about 500 mA + start surge so you need a 5V, 1 Amp power supply besides Arduino, might be able to cobble some connectors and a switch transistor into a small box or use something like this to switch pump power.
Thanks - I have a power module (700mA max) that might be suitable - the main Problem is, how to connect the USB port. My best idea so far is to cut off the USB and hope there are two cabels with different colours inside.
