Smart flashlight unlocking and message system

The invention relates to a smart flashlight unlocking and message system, in particular to a method for setting the brightness of a flashlight by using an APP program on a smart handheld device, converting into a Universal Asynchronous Receiver/Transmitter (UART), and at the door. The front end of the lock is a light sensing module that converts the light signal of the flashlight into an electrical signal and transmits it to the smart flashlight unlocking and message system of the system.

Pressing, forgetting to take the key and being troubled is a common experience. If you can use the items close to life, it is better. The mobile phone can now say that there is a manpower. If you can combine the unlocking with the mobile phone, you can Save the need to bring a bunch of keys.

It is also known that the general door lock only has the function of unlocking and locking, and has not heard the function of having a message. For example, students sometimes go to school to find a professor at school, but when they go to the office, they find that the professor is not there, but they don’t know where to look. They can only wait, contact by mobile phone or come back next class, but often come back next time, so If you can leave a message on the door lock to inform the professor that there is something to find him, you can skip the class time without waiting there, and save time, save time and convenience.
