We are pleased to announce that Lesson 7: Transistor Pushbutton is now posted. While the video will be posted at a later date, you will have enough necessary instructions to build a simple circuit using a transistor (in this case, a NPN 2222 bipolar transistor).
Transistors are handy switches that don’t need a mechanical input but can activate (or deactivate) current flow based on a voltage based input. While this introductory lesson uses the pushbutton to control the input, you will be able to handle breadboarding with the transistor.
The next few lessons will then dive deeper into digital logic using transistors and subsequently NAND gates.
