5号機のネジ留めに苦労したので、NANOとディップスイッチを基板にのせたバージョンを作ってみた。ずい分楽にはなったが、もっと楽にならないか。 BDアダプタ等への出力と赤外線リモコンセントへの出力ができる参号機の設定を少し変えて実装してみまし ...

O. What is RelayModule Library? If I use it, how easier life will be ? If you have made some Arduino project with Relay Modules, you probably wrote some scattered code for relays. Scattered Code ...

Normal: Manual control of each relay All ON: Activate all relays All OFF: Deactivate all relays Alternating: Alternate between odd and even relays Sequential: Activate one relay at a time in sequence ...

Overcurrent relays with inverse definite minimum time (IDMT) characteristics are widely used in power systems to protect ...

Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi with an ESP8266 ESP-01 module. With ...
