This video shows the LED behavior that corresponds to the plot for the PI system. In the video you will also notice an important hardware detail: the PCB we are using for this project actually has two USB connectors, one for power and one for data. A typical USB port cannot supply more than 500 mA. Thus, to get the higher current we need for the heating element, the board includes the option of taking power from a separate connector. So one of the USB cables is connected to a USB charger that can supply something like 1200 mA, and the other is connected to a USB port on the PC.
