hai,i have been trying with virtual reality glove project https://circuitdigest.com/microcontroller-projects/virtual-reality-using... since 5 days, and i am not able to get the clicks, i mean i made all the connections right in their position, but when i take magnet to sensors, there is no response in processing UI like "key one pressed" or "key two pressed"... and i noticed that my HC-05 bluetooth module led light is blinking same even after sucessfull connection with my laptop, its blinking the same even before connecting to my laptop. please help me with this as i have to show my demo tomorrow,
thank you so much in advance (i am using arduino uno instead of nano)

HC-05 not connecting with Laptop

You are on the right track, the probelm is that HC-05 is not getting paired with your laptop. You can easily say that by the way your LED blinks. Trying paring it to your phone to check if the blink rate chages this will help us make sure the bluetooth module is working fine. 

Then try to figure out why exactly it is not paring with your laptop. If you still cannotmake it, then may be the probelm is with your laptop bluetooth driver which does not allow you to pair with HC-05. In that case you either try finding the right driver or use a USB cable instead of bluetooth for the communicating your clicks to laptop
