A method for automatically adjusting an antenna and the system thereof are provided. The method includes driving the motor to rotate the antenna at first, so as to receive multiple first digital signals and record the position corresponding to the multiple first digital signals; comparing the multiple first digital signals to obtain the strongest first digital signal among them; driving the motor to rotate the antenna to the position corresponding to the strongest first digital signal; driving the motor to adjust the pitching angle of the antenna to receive multiple second digital signals and record the pitching angle corresponding to the multiple second digital signals; comparing the multiple second digital signals to obtain the strongest second digital signal among them; and driving the motor to rotate the antenna to the pitching angle corresponding to the strongest second digital signal.

Method for automatically adjusting antenna and system thereof

A flashlight lamp circuit with automatic light adjustment includes a flashlight charging unit for controlling charging of a main capacitor, a flashlight activation unit activating the flashlight lamp to project a flashlight on the photographed object according to a flashlight control signal, a light sensor receiving and converting a light from the photographed object into an electric signal, an integral circuit receiving the electric signal and having an adjustable circuit resistance. When the amount of flashlight reaches a required light exposure, the flashlight control unit extinguishes the flashlight lamp.
