As depicted, the system is divided in four units:
1. Electrical/mechanical unit of the infusion pump;
2. Module with a stepping motor and its controller
and alarms (buzzers and syringe presence led);
3. Arduino module controlling the operation of the
pump;
4. Display LCD for visual feedback of the
information.
Introducing all the control parameters in the web
interface, the information is processed in the
microcontroller and the pump is set to work as defined.
