It was the first step in building a framework to prepare, prevent, and respond to multi-sector cyberattacks on major cities. Jack Voltaic was a research experiment in the form of a cyber exercise that involved players from multiple sectors, including first responders, emergency management, transportation, telecommunications, power, water, finance and healthcare.

The exercise included two parallel tracks consisting of: 1 an on-range network defender versus attacker live-fire exercise LFX , and 2 a facilitated table-top exercise TTX among sector leadership focused on events occurring in the virtual range play.

Jack Voltaic 2. Making cities resilient: Houston takes a cyber stress test. This will give us higher resolution on the bit reading, which consequently is from 0V In the next section, the Arduino code used to measure voltage and current in real-time is introduced and explained.

The code was developed using the Arduino IDE version 1. These four variables will help us determine what is happening with the system over time during charging. Similar values should give confidence that the user has wired the components correctly, uploaded the code properly, and is following along closely with the expectations of the experiment. In the next section, a Python code will be presented that reads the serial outputs shown above and plots them in real time.

Later in the code, the outputs will be saved for analysis and post processing. At this stage in the experiment, the user should have a constant stream of voltage and current values being outputted by the Arduino board. In this section, a Python script will be used to read the Arduino serial data and plot the values in real time.

Python 3. The Python code for reading and plotting in real time is given below:. We expect to see several stages of the charge curve: a startup stage involving a rapid change in cell voltage, a constant current stage where the current is steady and the cell voltage is slowly changing, and finally a constant voltage stage where the cell voltage reaches an asymptote and the current decreases [read more about charge curves here ].

Typically, the maximum cell voltage is set to 4. The script above will create a visualization of the charge curve for the V25 battery.
