サーボモーターの角度はPWMで制御します。 PMW Period: パルス信号の周期(SG90の場合1秒間に50Hz) この周期の中でHIGHにしている時間を見てサーボモータの角度を調整しています。 Duty Cycle: 周期的な現象において、"ある期間" に占める "その期間で現象が継続さ ...
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 ...
サーボモーターを動かしたいとき、ライブラリを使用すれば簡単にそれが実現するが、ライブラリである以上何かしらの制約が存在する。例えば、Arduino UNOではピン9と10のPWMが無効となってしまう。また、他のライブラリとの競合が発生してしまうかもしれ ...
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 ...
Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...
This project can help a R/C model maker or robotic enthusiast to check and select the best servo testing it's power consumption and behavior before using it into a ...
Building IoT projects with touchscreens used to be a headache, involving numerous components, messy wiring, and endless troubleshooting. But the ESP32-S3 Box-3 makes things way easier. It is an all-in ...
