Hall sensors not detected, Bluetooth module light blinks continuesly and not being stable or any other state even after pairing

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
July 9, 2019 - 6:07pm

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

Bluetooth Module HC-05 Configurations
May 9, 2020 - 4:14pm

I think there is a problem with connection of your HC-05 and your laptop bluetooth module. For checking this, leave you circuit and just get HC-05 module and power it up with 5V power supply, can see the power LED turns ON, and there is LED start blinking which indicates that waiting for the bluetooth connection. Try to get access using your smart phone, if the HC-05 module is discoverable, if the module discovered and connected with phone, then you just need to update the drivers of bluetooth module installed in your system from device manager. Otherwise you can use external bluetooth module with your laptop/PC for this purpose. Here I recommend you to visit the SSLA platform for getting technical support from their technical support team regarding these kinds of issues.
