The button S3 on Explorer 16 board is connected to a pin of the Microcontroller. Mention the name/names, number of that pin, and the purpose of that pins.

The button S3 is connected to RD6, pin #83. Other Rows?

Some other ROW pins that are connected to buttons on the Explorer 16 board include:

- The button S6 is connected to RD7, pin #84. The purpose of this pin is to read the state of the button S6.
- The button S5 is connected to RD13, pin #89. The purpose of this pin is to read the state of the button S5.
- The button S4 is connected to RC14, pin #60. The purpose of this pin is to read the state of the button S4.

The button S3 on the Explorer 16 board is connected to the RD6 pin of the microcontroller. RD6 is pin number 83 on the microcontroller. It serves as a general-purpose input/output (GPIO) pin, which means it can be configured to be an input or an output by programming the microcontroller.

To find out the names, numbers, and purposes of the other pins on the Explorer 16 board, specifically related to the buttons, you can refer to the board's documentation or user manual.

Typically, such documentation provides a pinout diagram or a table that describes the functions and attributes of each pin on the board. This information will help us identify the names, numbers, and purposes of the other pins related to the buttons.

If you have access to the Explorer 16 board documentation, you can find the pinout diagram or table that corresponds to the microcontroller and buttons. It will likely have details about which pins are associated with buttons and their functions.

Please consult the documentation related to your specific Explorer 16 board to identify the names, numbers, and purposes of the other pins connected to buttons.
