Be careful not to connect any other red power cables to the one leading to the battery, as it transmits higher voltage, which, while harmless to us, can still fry your controller and LED lights. Once you solder the connection between the battery and the voltage regulator input 9V terminal, connect everything else in this project to the regulator's 5V output pin.
