Here we have a USB Logger. We can talk to the Logger using any terminal program such as BlueTerminal. When we press Enter, we can see the menu. We can press A to select 5 channels to log. We can press P to set the log period time to 5 seconds, and then we can press V to start logging voltages. We can adjust the trimpots to see how the voltages change. In BlueTerminal, we can select TimeStamp and Log to start logging.
