The NE555 Delay Timer Relay Module is a time delay switch module based on the NE555 timer IC. It allows users to control the ON delay of a connected load with adjustable timing from 0 to 10 seconds. This module is ideal for automation projects, DIY electronics, time delay functions, and simple control circuits.

It works on a 5V DC supply and includes an onboard relay for switching AC or DC loads. The potentiometer allows easy adjustment of the delay time. Once triggered, the relay activates after the set delay period, making it a useful timing control device in various electronic applications.
