Intro: How to Use Relay Module With Arduino
Hello dear friends;
In this project i have tried to explain how to use Relay module with arduino. This module very usefull and IMPORTANT for us.Because,it is very common component for home automation.You can use with 220V just from your electricty socket.
IMPORTANT NOTE: If you going to use with city electricty(220V OR something like dangerous) take your own precautions.DO NOT TRY TO ATTEMPT USE IF YOU DON'T KNOW HOW TO USE 220V(or something like dangerous).Otherwise it may cause DEATH!!!!!
However,i have used 9V 850mA adapter and SIMPLE LED.My purpose in this video and article is how can we use relay module with arduino. After this article u will be learned how it works and understood basic working ideas of relay module.
Relay module means it is OFF or ON State.When its ON ,current will pass through the relay and system will work.When its OFF, current will not pass through the relay and system will not work.
Also i have used 1 simple button in order to show you guys how to controll LED with RELAY .
x1 Arduino UNO
x1 Relay module(Just like in the video it is very cheap and common )
x1 9v (500-1000 mA ) adapter.
All the codes(arduino) and circuit diagram (fritzing) has been uploaded here and on github(some kind of Turkish letters if you use github link): https://goo.gl/0S28cF
If any question or suggestion, here or on YouTube channel please... Good Luck,Have Fun!
Sorry for my English if i made mistakes :/
