Version 1.0

Version 1.0 and Its Subversions

Version 1.0, "V1" incorporates basic functions of the Arduino modules used to manifest the robot.

1.1

Using the measurements made by the ultrasonic distance sensors, v1.1 uses basic logic to dictate the voltages written to the motors. Trial and error will be required to find what voltages make a motor move a certain way, but other than that, this is a straightforward sketch.

1.2

V1.2 builds upon v1.1 by intorducing PWM control to the speed of the motors. However, this sketch does not change the speed motors as the conjunction of digital and analog write functions was sufficient to make a PoC for later versions.

1.3

V1.3 adds an SD card to v1.3 for the intended use of logging actions taken by the logic code. The SD card is also intended to be used in later versions for diagnostics.

1.4

V1.4 is the "smarter" version of its precedents as it introduces dictation of PWM. This sketch essentially produces more fluid robot movements in comparison to v1.1 and v1.2.
