Have you ever ever puzzled why smartphones are referred to as smartphones? As a result of they’re sensible, proper? They do some jobs mechanically, intelligently. That is the brief reply. For instance, cellphones have an computerized brightness management system, which may be very helpful. However for unknown causes, computer systems don’t have an computerized brightness management system. To alter the brightness, every time it’s important to press some buttons (operate keys). And on some computer systems, some key combos work (often fn + operate key).
To beat this drawback, a easy system has been designed that may be related to any PC and the brightness of the PC will likely be managed mechanically, similar to our telephones.
The system was constructed on PCB however it’s attainable 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.
