Arduinoでトランジスタを活用する方法はいくつかありますが、主にトランジスタはスイッチやアンプとして使われます。ここでは、スイッチとしての使用例に焦点を当てて説明します。これは、Arduinoのデジタル出力の電流が不足している場合に、より大きな ...

A teacher I know is stuck, with only npn transistors in the supply cupboard and the need to create a reversible motor drive for an Arduino project. Reversing ‘bridges’ have four switches (relay ...

The transistor is probably the most important invention in electronic engineering and the basis for nearly all integrated circuits (ICs). The transistor is a three-terminal electronic device that can ...

Manufacturing companies, particularly those that mass-produce electronic circuits, work pretty much around bipolar junction transistors, like PNP and NPN. However, choosing between these two BJTs can ...
