注意点 電源：リレーが消費する電流に注意してください。必要に応じてArduinoよりも高い電源をリレーモジュールに供給することが必要です。 電気的ノイズ：リレーを使用する際には、電気的ノイズやスパークが発生することがあります。適切なスナバーやフィルターを使うことでこれを抑制 ...

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 ...

IN - This pin is also called the control pin because it is used to control the output of the relay. COM - is connected to the device you intend to connect. NC - terminal is connected to the COM ...

The concept of automation is getting popularity among people these days and many of them control their lighting, climate, etc remotely at their homes. Several microcontrollers or microprocessors can ...

An Arduino nano and relay module with 4 relays (see picture above) was used to simulate and replace the guitar 3-step switch. The project for Arduino is in PlatformIoClamp15. Node-red was used to ...
