In exploring the use of analogWrite() and digitalWrite() on the Raspberry Pi Pico using Arduino, I have discovered some strange behaviors when switching between those modes on the same GPIO pin. This ...

前回に続きNucleo Board STM32F303K8とArduino IDEの組み合わせでの使い方を覚えていこうと思います。今回はPWM出力です。 使い方 普通のArduinoと同じようにanalogWriteが使えます。 ひとまず、LEDが接続されているD13ピンにデューティ0x40で出力してみました。 void setup ...

When multiple PWM converters are connected in series (or in parallel) in a power electronics circuit, it is appropriate to run all converters at the same frequency but with certain phase shift among ...

Arduino UNO R4互換ボードでモジュラーシンセのVCOを試作したので備忘録。 背景 2023年にArduino UNO R4がリリースされた。 他のマイコンボードと比較して、処理速度や価格で劣るため、少し使いにくい感じもする。 一方で、入出力が5Vに対応しているため ...

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 ...

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 project we will develop a tone generator using Arduino Uno. We will have buttons interfaced with the UNO and each one of them generates different intensity of tone. The frequency of tone ...
