MOSFETのピンの順番は、必ずデータシートで確認する必要があります。 Pay attention to the diodes, MOSFET, and the relay: the diodes are polarized, the MOSFET must have the flat side facing the right way, and the relay needs to have the stripe at the proper end for everything to work. ダイオード、MOSFET、リレーに注意してください。ダイオードは極性があり、MOSFETは平らな面を正しい方向に向ける必要があり、リレーはストライプが正しい端にないとすべてがうまく動きません。 If you look at Figure 8-5 and Appendix D, you’ll notice that some components, like resistors, light sensors, and (some) capacitors, have circuit symbols that are symmetrical, in that you can flip them upside down and they look exactly the same, while other components, like LEDs, diodes, and MOSFETs, are not symmetrical. Resistors, light sensors, and(some) capacitors are unpolarized, meaning they work the same regardless of which way the current flows through them, while components, like LEDs and diodes, are polarized, meaning they work dierently depending on which way the current flows through them. Similarly, MOSFET pins have very specific functions, and can’t be used interchangeably.
