Review on 🐠 Efficient Dosing Pump 12V Peristaltic for Aquarium Analytical Applications by Dang Esq

I ordered this pump for an Arduino project a while back. After reading a document on powering and controlling peristaltic pumps I gave it a try. I tried different circuits and power supplies, none of them worked. This is a very simple transistor diode resistive circuit with a separate power supply that I can easily use to control many other pumps and motors. With this step and 12V supply it initially worked for a few seconds and then switched off. After reading all the other comments I really don't blame anyone but myself. Take my advice and everyone else, don't buy this junk. Buy a pump from a company that has enough decency and modernity to provide a damn specification.
