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 ...

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 ...

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 ...

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 ...

Relays are frequently used in our electronics applications specially when we need to drive high loads from microcontroller circuits. So in this DIY project, we make a 4-Channel Relay Driver Circuit to ...
