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 ...

Note: Some pins are not connected on a standard Arduino Uno R3 but still listed so you can use them if you had a custom board. It might also be possible that your ISP header of the 16u2 is flipped 180 ...

ATmega328P/PBのレジスタをちょこっと変更して、任意のPMW周波数へと変更するための方法について、簡単にまとめます。 ATmega328Pには、3つのTimerが内蔵されています。Timer0, Timer1, Timer2の3つです。（328PBでは、Timer3, Timer4の2つが追加されています。） Timer0は ...

I myself own an Arduino Uno R3 and found that it can simplify my projects development and microcontroller programming, but sometimes I need to know the Arduino pinout. That is why I have written this ...

If you are planning on building a robot with DC motors then you will eventually learn that you need to control both the speed and direction of the motor if you want it to move it in a certain ...

LEDの明るさを変えたり、モーターの速さを調整したり。そんなときに使われるのが「PWM制御」という技術です。 この記事では、Raspberry Pi（ラズパイ）で使える2つのPWM制御方法「ソフトウェア制御」と「ハードウェア制御」について、初心者向けにわかり ...
