This tutorial provides sample circuits to set up a 555 timer in monostable, astable, and bistable modes as well as an in depth discussion of how the 555 timer works and how to choose components to use with it.  The 555 timer is a chip that can be used to create pulses of various durations, to output a continuous pulse waveform of adjustable pulse width and frequency, and to toggle between high and low states in response to inputs.  By wiring the 555 timer with resistors and capacitors in various ways, you can get it to operate in three different modes:

This video demonstrates constructing a basic circuit with a common integrated circuit/microchip, the 555 timer. This versatile device can be configured to control servo motors, create music or support many functions controlled by pulses. The video introduces pin numbering conventions for DIP devices and demonstrates reading a simple circuit diagram.
