DIY Relay module

The reason i come up with this tutorial is last week i needed to make a project so fast(its a urgent project for my college) i needed a relay module to finish the last stage of the project, unfortunately i screwed . there is no relay module left in my garage . So, i went to a local store to buy one but there is no 5 volt or 6 volt relay module.But fortunately they have the relays , i bought so many(hope i can use like this situation in future :D) .then made one myself. Its cheap and easy , you can save a little bit money by making these Diy relay module . At the same time you can use this relay module like a ordinary relay module. I made a single channel but you can make more on a same PCB.”
