Have you ever ever puzzled why smartphones are known as smartphones? As a result of they’re sensible, proper? They do some jobs robotically, intelligently. That is the brief reply. For instance, cell phones have an automated brightness management system, which could be very helpful. However for unknown causes, computer systems don’t have an automated brightness management system. To vary the brightness, every time you need to press some buttons (operate keys). And on some computer systems, some key mixtures work (normally fn + operate key).
To beat this downside, a easy machine has been designed that may be linked to any PC and the brightness of the PC will likely be managed robotically, similar to our telephones.
The system was constructed on PCB however it’s potential to simply construct it with exterior jumpers given the simplicity of the circuit. That is made up of an Arduino Professional Micro, however you should use the Nano or no matter you need, an LDR photoresistor and a 1KΩ resistor.
