秋月の格安太陽電池(ETM250-1.5V)300円を2個使ってLEDを点灯させる実験です。数mA程度で光る高輝度LEDでないと満足な明るさは得られないようです­。
I tried to connect Akizuki cheapest Solar battery module to LED.Please make sure LED's Brightness
and Room's Brightness.

  • 僕もこれもってます。前に初めて太陽電池を購入したときに、とり­あえずテスト程度に買ってみました。

    自分の眼で電流計や電圧計を見て確認したので、より一層ベストを­尽くす見解が出来上りましたね。
