Have you ever ever puzzled why smartphones are referred to as smartphones? As a result of they’re good, proper? They do some jobs mechanically, intelligently. That is the quick reply. For instance, cellphones have an computerized brightness management system, which could be very helpful. However for unknown causes, computer systems haven’t got an computerized brightness management system. To vary the brightness, every time it’s a must to press some buttons (perform keys). And on some computer systems, some key combos work (often fn + perform key).
To beat this drawback, a easy gadget has been designed that may be related to any PC and the brightness of the PC can be managed mechanically, identical 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.
