555 Hi Voltage Osc 555 Multivibrator w/ diode 7555 Monostable, meant to drive a lightweight motor from a low voltage source. Dice Oscillator

This circuit will oscillate at max speed using standard 555 calculation before slowing down and stopping.  This will create a dramatic effect for game circuits such as dice or heads / tails. 555/556 Design Data and Schematics

Includes the math and schematics needed to design with these chips.  Lifted out of the data book for the most part. 555 Fader 03 555/556 Design Data and Schematics Page 2

A basic shift register approach to sequencing. 555 hetrodyne Sequencer Bar Graph Style 02

How to use a 4017 and 4071 to do this job. 555 no variation oscillator w duty cycle 555 Flashing Police Lights V11 555 Flashing Police Lights V20 LED Flashers, Group 1

These are basic 555 LED flashers.  All of them alternate between the red and green LED.

Flasher 1 - This configuration of LEDs will work on all 555's.  There are LEDs where both these colors are in the same package, in which ca
