Previously, he came across several projects in which this microcircuit is used, but he did not know exactly how it works. To better understand the principle of operation of the microcircuit, he decided to make this simple device.
The NE555 Timer IC is an extremely reliable and stable 8-pin device that can work in a variety of devices, as a very accurate monostable, bistable or unstable multivibrator for various applications such as one-shot or delay timers, pulse generation, LED and lamp flashers. alarms and tone generation, logic clocks, power supplies and converters, etc., virtually any circuit that requires some form of timing control.
In this project, the master is going to manually control the “trigger” circuit in the NE555 timer with 2 buttons. One button turns on the trigger circuit and lights the LED, the other button resets the trigger circuit by turning off the LED.
Tools and materials: -Ne555 chip; -2 tactile switches; -LED; -470 ohm resistor; -9V battery; -Battery connector; Pitch first: connect button
The round dot in the upper left corner of 555 timer shows pin number 1. Below will be pin 2 and so on.
Simple NE555 diagram You need to solder a button between pin 1 and 2. This button will turn on the LED.

To protect the LED, a 470 Ohm resistor must be soldered to the third leg.

Now you need to solder the LED between the button and the resistor. The anode (+) of the LED is soldered to the resistor, the cathode (-) to the button. It is advisable to bite off the protruding legs of the LED.
