Pi Pico W でブレッドボード上のLチカ
Pico W本体のLEDじゃなくてブレッドボード上のLEDを光らせたい。
できた。
スマホからオンオフできる（AROMA ONするとLED点灯）。
Pico W はこないだハンダ付けしたやつ
回路はこう。今回はLED1つだけにする。GPIOの16番とGNDだけを使う。
クルッとひっくり返してるのでオモテウラが逆なの注意。
Thonnyが一番シンプルで使いやすい。VS Code とか Arudino IDE とかだとPi Picoを認識させるまでがホント大変。
ThonnyだといったんBOOTSELで接続してファイルを送り込んだPicoなら、次からはUSB繋いだ瞬間に右下に認識してくれる。
Tonnyの使い方ざっくり
次はフルカラーLEDを試す。
