    USB Rx/Tx LED indicator

    No, he didn't. He only gave me some clues but it's not a complete solution to my homework. Without a circuit diagram it can't be that easy.

    USB Rx/Tx LED indicator

    Thanks! I know electrons flow but that was just a unofficial language of mine. I don't want to monitor the packets of the data lines but I jest need an indicator whenever there is a data transfer. So, do you know the circuit diagram for that? Can it be done using a MOSFET or is there any IC for...

    Fixing the 7-segment LED of Sony sound system In

    I have one Sony 5.1 sound system but its 7-segment LED display is not working properly because the numbers (volume level) are not showing up completely and all the segments don't light up. Sometimes, the whole display shows nothing at all. I have also noted that when I turn ON and OFF the...

    USB Rx/Tx LED indicator

    I mean the data lines (D+, D-), and whenever there is a data transfer, there is a voltage flow. So, I need a simple circuit that will make the LED glow when voltage will flow in the D- and D+ lines.

    Fixing the 7-segment LED of Sony sound system In

    I tried all that but didn't work. Here is a video of the problem. Every time I turn the system ON and OFF, the display code changes. https://drive.google.com/file/d/1ZAODA4ofbmZIdgiM70HkjAqu7zD6-s_i/view?usp=drive_link Please check the video on the above link.

    USB Rx/Tx LED indicator

    I need to make a LED light up whenever there is a data transfer between a USB storage device and the PC. During the data transfer the voltage in the Rx/Tx lines is about 1 volts. So, how do I make an LED light up after detecting that voltage? Can it be done using a MOSFET?

    That's okay but without earning money, life can't go on. I wonder how contributors are able to keep up their work without earning.

    Fixing the 7-segment LED of Sony sound system In

    I have one Sony 5.1 sound system but its 7-segment LED display is not working properly because the numbers (volume level) are not showing up completely and all the segments don't light up. Sometimes, the whole display shows nothing at all. I need to know whether the LED driver IC (PTC 6955) is...
