LED Circuits - Light Emitting Diode Electronic Circuits

Create alternating flashing LED's with this 555 timer based LED flashing circuit. Perfect for warning sign or model railroad crossing signal.
Uses an LTC3201 to provide an adjustable ultra-smooth supply current to white LEDs.
An interesting LED electronic circuit that works as a meter for measuring audio levels. The more LED's - the higher the audio volume!
This circuit uses a 555 timer and a counter/display chip in order to create the illusion of 8 randomly flashing LEDs.
