As discussed a transistor will act as an Open switch during Forward Bias and as a closed switch during Reverse Bias, this biasing can be achieved by supplying the required amount of current to the base pin. But this junction breaks by applying a proper biasing voltage across transistor pins. This is a tone control circuit, the small-sized. https://youtu.be/mSfb-NLDgKQ2: Top 5 Arduino Writing Machine 2018 | Homework Machine For Students :( https://youtu.be/2SOU9_VYqTs )     3: Base electronic tool kit from Amazon at just Rs 499.https://youtu.be/i2H6K1PARbo4: how to make a touch switch using 555 IC Diy.https://youtu.be/1r3EtzAzH_w5: how to make a LDR darkness sensor circuit Diy.https://youtu.be/qA_QBdQCTlQ6: How to make a touch switch using Irfz44n MOSFET. A better alternative for switching applications will be 2N2222. The equipment that use to replace such as Q1 = 2N2222 use other numbers can replace almost be finished request a kind NPN alike enough such as BC549 or BC337 or C1815 or C945 etc. C945 is a general-purpose NPN transistor that widely used in a variety of commercial and educational electronic circuits.
