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 ...

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 ...

アンプやフィルターなどの製作をしているが、チェックの際にノイズの混ざったリアルな電気信号を使いたいということで 今回作成するのは擬似ノイズ信号作成装置である。 今回もChatGTPにすがりつきながら製作していく。 大まかに次の3つからなる ...

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 ...

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 ...

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 ...
