What the 555 Timer Does
In monostable mode a trigger starts one output pulse whose length is set by an external resistor and capacitor; larger values give a longer pulse, which makes a simple time delay. In astable mode the output keeps switching between high and low by itself, so the chip acts as an oscillator, for example to flash an LED. Used as a flip-flop (bistable), it holds its output high or low until it is told to change. Derivatives put up to four timers in one package.
Handling DIP Chips
Pin 1 sits next to the notch or dot on the top face, and the pins are numbered anticlockwise from there when the chip is viewed from above. Insert it the right way round into a breadboard or IC socket, with the pins straight, and check the supply connections before switching on, as a reversed supply can destroy the chip.
