Before you continue, remember that if you will connect the relay to High Voltage then incorrect connection or improper use could result in serious injuries or death. So be very caution of what you are ...

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 ...

This device enables generic loads (here: valve actuators) to be controlled by TCP/IP. The power for the relay card and the Arduino Pro MINI is derived by a POE 802.3af ethernet switch. A Texas ...

In this project, we are going to build something very simple project, a temperature controlled relay that is used to turn on a dc fan. You can actually change the DC Fan to other electrical devices ...

In electronic and industrial automation systems, relay modules play a crucial role by allowing low-power control signals to switch high-power devices. Selecting between a 5V relay module and a 12V ...
