Arduino Mega 2560 Code to that supports a standard Ethernet Shield .

i.e. Drive Relays hence outputs to MFJ-993b.

Supports Up and Down for manual L and C Tuning, Autotune On/Off, Antenna Selection 1/2 and 100ms Short /1000ms Long for Tune.

Op Note 1: You may need additional power for the 5V relay board; sometimes you can power the 5V relay board from the Mega 2560 - but reset/start the device first and then connect power to the relay board.

Op Note 2: You will need determine pinouts to the MFJ-993b DB9 yourself. This is easy to determine; refer to the manual at https://mfjenterprises.com/products/mfj-993b#product-manuals

*Note for ESP32*

See https://github.com/dl9sec/MFJ-993WWRC for working with ESP32 modules. It works very well with the MFJ-993B and is a great project! Opto-Isolators are recommended rather than FETs ! Enhancements to this may appear that include additional functionality that this project incorporates.
