Contactless AC Current Tester | 555 Timer IC | Easy and Useful Project

Hey guys, welcome back to Prabha's Creative experiments. Have you ever seen a current detector used to find the flow of electric current in the wires? Sometimes an electric tester is also used to serve the same purpose but a problem associated it with is that we need to touch its tip with the wire. It needs physical contact between the tester and the conductor which is sometimes not possible due to the insulation of wires. So in this article, we are going to make an AC/DC current detector circuit using IC 555. Please follow the steps carefully to make your own current detector
