This LED DIMMER is an Arduino Uno based PWM (Pulse Width Modulation) circuit developed to get variable voltage over constant voltage. The method of PWM is explained below. Before we get start building ...

The creative adventures with ATtiny series microcontroller are awesome if you know how to play them. ATtinys — especially the ATtiny85s — are all around us, and by using one, we can shrink the size of ...

ArduinoでDCモーターの回転をPWM制御で行うところまではできた。 問題は、実際のターンテーブルが、できるだけ正確に、そして安定して33.3回転を回ってくれる事が大事である。 ところが、実際に回してみると、どこかで回転のロスが出ているのか、抵抗が不 ...

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 ...

The 16-channel 12-bit PWM/Servo Driver, PCA9685, is an ideal module for precise control of multiple PWM outputs that are commonly used to control servos, LEDs, and other devices in applications such ...

Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using the ...

もっと使うゼ!!Arduino!! 前回に引き続き、今回もArduinoについて。前回はArduinoの基本の“キ”あたりをご紹介したが、今回は基本の“ホ”あたりを。前回紹介した作例より、ちょっぴり高度なものをいくつかお見せしたい。 イタリア生まれのマイコン（AVR ...

今回は、Arduinoでの赤外線リモコンの使い方についてご紹介します。 赤外線リモコンとは、身近なもので言えば、TVやエアコンのリモコンです。 赤外線リモコンを使うには、リモコンから送られてくる赤外線信号を受信するための、赤外線受信モジュールが ...

As more complex calculation and check inside ISR are introduced from v1.2.0, there is possibly some crash depending on use-case. You can modify to use larger HW_TIMER ...
