Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

Arduino-fanciers Oomlout have put together a neat control box for the popular prototyping board, complete with five potentiometers and three switches. There's also a software app that can monitor the ...

マイコンから制御できる電子ボリュームは何かないかと探していたところ、aitendoで三菱のM62421FPという安価なチップが目にとまりました。ボリュームだけでなくトーンコントロールもできるようです。 ネットで検索するとルネサスのデータシートは日本語な ...
