+This module includes an arduino sketch designed to run on the ESP32.
+
+The sketch takes simple input from serial (ESP32 microusb port), and converts the input to a duty cycle that can be used on servos.
+
+The protocol specification is as follows, assuming an array of bytes:
+
+
+| Byte Number   | Value Description |
+| :---------- |  ----------: |
+| 0 | 0 if Calibrating a servo. Higher values indicates channel number to set duty cycle on. |
+| 1 | If byte 0 = 0: number of servos to calibrate. Else, the new duty cycle value for the channel specified in byte 0. |
+
+When setting the duty cycle, the current min angle is 0, and the max angle is 255, which allows the entire byte to be used for setting the duty cycle.
+
+The table below describes the byte format for calibrating a servo. This array of bytes can be repeated for the given number of servos in byte 1:
+
+| Byte Number   | Value Description |
+| :----------   |  ----------:      |
+| 0             | Servo channel to set (this will be byte 0 when setting duty cycle, so don't use 0). |
+| 1             | The pin number to setup |
+
+The min/max pulse widths are hardcoded to 1000us/2000us respectively. 
+
+At the end of each loop, the entire array will be read, to flush any data that may cause issues later.
+
+Upcoming (TODO):
+- Use bit shift to allow 12 bits to be used for the duty cycle range, as there can only be a max of 16 channels anyway (4 bits).
+- Consider protobuf or msgpack for serialisation format, for more advanced use cases, and more maintainable communication formats (currently changing the message format will require changes to the entire protocol)

+
+This directory is intended for project header files.
+
+A header file is a file containing C declarations and macro definitions
+to be shared between several project source files. You request the use of a
+header file in your project source file (C, C++, etc) located in `src` folder
+by including it, with the C preprocessing directive `#include'.
+
+```src/main.c
+
+#include "header.h"
+
+int main (void)
+{
+ ...
+}
+```
+
+Including a header file produces the same results as copying the header file
+into each source file that needs it. Such copying would be time-consuming
+and error-prone. With a header file, the related declarations appear
+in only one place. If they need to be changed, they can be changed in one
+place, and programs that include the header file will automatically use the
+new version when next recompiled. The header file eliminates the labor of
+finding and changing all the copies as well as the risk that a failure to
+find one copy will result in inconsistencies within a program.
+
+In C, the usual convention is to give header files names that end with `.h'.
+It is most portable to use only letters, digits, dashes, and underscores in
+header file names, and at most one dot.
+
+Read more about using header files in official GCC documentation:
+
+* Include Syntax
+* Include Operation
+* Once-Only Headers
+* Computed Includes

+This directory is intended for PlatformIO Unit Testing and project tests.
+
+Unit Testing is a software testing method by which individual units of
+source code, sets of one or more MCU program modules together with associated
+control data, usage procedures, and operating procedures, are tested to
+determine whether they are fit for use. Unit testing finds problems early
+in the development cycle.
+
