LED controller with bluetooth

A LED controller with Bluetooth, comprising:

• a mobile terminal for issuing the manipulation instructions;
• and
• a control module with Bluetooth, which is wireless communicating with the mobile terminal, so that the manipulation instructions from the mobile terminal are converted to a control signal that is output;
• and
• a driving circuit connected to an output terminal of the control module with Bluetooth, controlling of turn on or off a control signal provided by the control module with Bluetooth,
• also comprising an input module, which alters the modes of a string of flash lights of the loaded LED lights and is used to reset a password of the control module with Bluetooth, the input module is electrically connected to the control module with Bluetooth;
• the driving circuit is a bridge driving circuit, which including a first transistor, a second transistor, a third transistor, a fourth transistor, a first resistor, a second resistor, a third resistor and a fourth resistor;
• a first base of the first transistor is connected to a collector of the fourth transistor by the first resistor, and the base of the first transistor is connected to a output terminal of a DC power supply by the second resistor, and a collector of the first transistor is an output terminal, and a base of the fourth transistor is connected to the output terminal of the control module, and an emitter of the fourth transistor is electrical grounding;
• a base of the third transistor is connected to a collector of the second transistor by the third resistor, and the base of the third transistor is connected to the output terminal of the DC power supply by the fourth resistor, and a collector of the third transistor is an output terminal, and a base of the second transistor is connected to the output terminal of the control module, and an emitter of the second transistor is electrical grounding;
