 ## Project Overview
 
 The **FlowCycle Pump** is an Arduino-based controller designed to automate precise cyclic timing intervals for laboratory pump operations. It was developed as part of a scientific study at the Center for Health Sciences (CCS) at the Federal University of Pernambuco (UFPE), Brazil.
