Sequencers: PLC sequencer performs ON or OFF output patterns using sequencer instructions. The sequencer output instruction is used for controlling the output devices. Programmable Logic Controller (PLC) sequencer instructions are used for controlling machines which provides a stepped sequence of repeatable operations. It simplifies the ladder program by allowing the user to use a single or pair of instructions for performing complex operations. Various sequencer instructions can be programmed based on the PLC manufacturer.

Java Graphics (Bonus In this lab, we'll be practicing what we learned about GUIs, and Mouse events. You will need to implement the following: A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: O о о ○ An input button to register your mouse to the drawing panel. A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels. " The x position of the points cannot go further than the You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel containing the buttons, and a GridLayout to hold the drawing panel and button panels. Regardless of how…
