Controlling 220v using arduino relay board
Sumber : http://browse-tutorials.com/tutorial/controlling-220v-using-arduino-relay-board Controlling 220v using Arduino relay board This guide shows how to control 220 / 230 V using relay board. This is very general relay board, you can find it in ebay, amazon and even in some local stores. This is a general board 5v relay that can control 250V AC, 125V AC, 30V DC or 28V DC. I live in Europe so my household electricity runs on 230V which fits nicely in the 250V limit. The board relay says it is up to 10A, but I wouldn't use that much on it. In this example I am trying to switch a lamp or if to be more exact a household socket that runs on 230V and you can put any item you have in your home to work on it. My board has 2 relays, but in this example I am going to use just 1 relay. You can modify the code on what ever amount of relays your controller can bare. Relay boards are available with 1, 2, 4, 8 and even 16 relays. The amount of relays you control is not restric
