The system uses a pic processor. It is programmed for a delay time to turn things on and off. It can control just one mod or it can control as many as you want.
You can build it yourself or you can buy the HIVE from AcidMods. This is just part of what the HIVE mod will do.
If you want to write the programming yourself then I can make you a small schematic on how to do it.
You will need a programmer to program the PIC processor.
