Steps to make an LED Blink to Music Having a Transistor

For any simple electronics project, making an LED blink to music having a transistor is all about as simple as they are available. If you have your soldering iron and solder, it's also an affordable project using the parts you'll need usually costing under $5 at any electronics parts supply store. After you have your parts, you may be finished in under an hour or so.||LED driver Module

        1

        Run electrical wire in the positive terminal from the 9-volt battery towards the positive leg on among the LEDs by hooking up an alligator clip towards the terminal and running the wire in the alligator clip towards the positive leg from the first LED.

        2

        Connect the LEDs in series by wiring the negative leg from the first LED towards the positive leg from the second LED, then your negative leg from the second LED towards the positive leg from the third LED.||LED Light Module


        3

        Wire the negative leg from the third LED towards the middle pin from the Tip31 transistor.

        4

        Wire the best pin from the from the Tip31 transistor towards the negative terminal from the battery while using alligator clip as pointed out in Step One.

        5

        Prepare the earphone cable by clipping the cord before it reaches the earphones. While using wire strippers, strip the rubber or plastic coating back about 1 " to reveal the 3 wires inside.

        6

        Connect the red-colored or whitened wire in the earphone cable 'either works' left pin from the from the Tip31 transistor. Then connect the floor wire right pin in which the link with battery can also be situated.||LED Panel Light

        Solder all of your connections.

        8

        Plug the earphone wire right into a seem-producing source, switch on the background music and revel in.

Tips & Alerts

    Each LED requires 3 volts to operate. If you want to include more LEDs, you should also improve your energy size consequently.

    The quantity of electrical wire you'll need is dependent how far apart you need to space the LEDs.

    Change things up with various color LEDs.
