Use Case: Remote Motor Control

To demonstrate how our touch kits and panels can be integrated with common use cases, consider the following demo. The 2.71” Touch kit was integrated into a DC motor control system. The motor rotates in both directions at the touch of a screen button. An overview of the remote motor control system is shown below.

Overview

Using a modified PDLS-Basic-Touch library, two buttons are shown on the 2.71” EPD screen. An ON button sets the motor angle at the 0 deg position. An OFF button sets it at the 360 deg position. Switching from ON to OFF, rotates the motor clockwise once while OFF to ON does it counterclockwise. At the touch of either button, a command is sent by the ESP32 server to the ESP32 client. The client then drives the motor accordingly.

A detailed description of the hardware assembly is shown in the next page. Software libraries used are also discussed after.
