The HMI allows machine designers to design control interfaces that are intuitive to the operator. The HMI is a critical component to the machine operator’s success in running the designated automation properly and efficiently. Therefore, the User Experience (UX) of the HMI is an important aspect of the machine’s operation. In this session, attendees will explore a method of automation control using Firmata. A desktop personal computer (PC) or laptop computer along with Firmata will allow attendees to read sensor data and control a Servo motor using this computer-based HMI software.
