Hello folks, nice to see you again guys!!! Today in this project, we will create Door Bell PCB using IC NE555. This project works by pressing either both of the push buttons or one of them. In this project, we use NE555 as IC. Before that, I will explain the IC NE555.

Now we go on and I will explain what is NE555?

NE555 is one of the most common chips used in the timer circuit. The NE55 IC is an 8-pin chip with 2 inputs and outputs. So basically IC NE555 can be used in many circuits and projects. Most projects are by adding capacitors and resistors to produce a CIRCUIT known as DELAY circuit time and the chip has pin-detection and amplifier (also called Power Amplifier) for output products. read more
