You can not control switching on/off your home lamp or laundry directly with arduino or microcontroller. To do that you need relay module.
This relay module consists of 2 relays. Each relay is connected to a current buffer so that you can connect them directly to a Microcontroller or Arduino.
Using these relays you can easily control high power devices or appliances using arduino or microcontrollers, the relay is rated for 230V 10Amps. The Module has 5 LED's, one for power and 2 for indicating relay signals.
Specifications
Rating: 10A (250V AC or 30 V DC)
Input (Control) voltage: 5V DC
