PROGRAMMABLE CODE

PROGRAMMABLE CODEIn technical literature there are many publications on improvised electronic code locks — variety of complexity and management that is performed on chips as small and medium scale integration and microcontrollers. Unfortunately, most of the first it is impossible to quickly change the code, since it is necessary to solder a jumper, or make other changes to the installation. In others, although provides for reprogramming of the microcontroller, but a very limited number of times. Furthermore, these modifiable combination locks consume in standby current of approximately 1 mA, which makes pay attention to the selection of source of energy when you use the above devices in both local (field) conditions where it is impossible to use network adapters.
