this paragraph Seven key dimming and color adjusting band wireless desk lamp programme , Master chip acquisition use DLT8T02S series Touch chip , The package model is 8 Pin SOP, By designing the circuit , The following functions can be realized ：

Plug in the power socket , Buzzer 1HZ The frequency rings three times , All white indicators light up for three seconds and then go out , Enter standby mode ; The power on nixie tube does not display completely

（1） Touch the switch button , Buzzer 1HZ The frequency rings three times , The corresponding white switch indicator light stays on , The digital tube is always on “00”,

Enter the power on state ,

If the two mode keys are not operated in the startup state , be 30S Rear buzzer 1HZ The frequency rings three times , The white switch indicator light goes out , The nixie tube goes out , Enter standby mode ;

When the function mode or working state is selected , Touch the power switch again and the buzzer rings , The function indicator light goes out , The white switch indicator light is on for a long time , The digital tube is always on “00” , Enter the power on state

（ If you do not operate the key in the startup state , be 30S Rear buzzer 1HZ The frequency rings three times , The white switch indicator light goes out , The nixie tube goes out , Enter standby mode ）

（2） In the power on state , Touch fruits and vegetables 、 Grain function button , Fruit and vegetable indicator 1HZ Frequency flicker 3S, The buzzer rings , fruit

The vegetable indicator is always on , The nixie tube lights up “10” The generator starts working , Nixie tube countdown ;

If in 3S Touch fruits and vegetables again 、 Grain function button , Then switch to grain indicator 1HZ Frequency flicker 3S, The buzzer rings once

The sound , The grain indicator is always on , The nixie tube lights up “08” The generator starts working , Nixie tube countdown ;

（3） In the power on state , Touch the meat and seafood function button , Meat indicator 1HZ Frequency flicker 3S, The buzzer rings , meat

Class indicator is always on , The nixie tube lights up “12” The generator starts working , Nixie tube countdown ;

If in 3S Touch fruits and vegetables again 、 Grain function button , Then switch to seafood indicator 1HZ Frequency flicker 3S, The buzzer rings once

The sound , The seafood indicator is always on , The nixie tube lights up “15” The generator starts working , Nixie tube countdown ;

（4） After the countdown , All indications are off , Generator does not work , Enter standby mode .

（5） Two generators can work at the same time , The operation of the two function keys does not affect each other . When the generators on both sides are turned on at the same time , Nixie tube and corresponding indicator 5S Switch the display .
