For advertising and promotion, light chaser circuits are used to produce lighting animation sequences to attract attention like the movie theater marquee. The device contains a lighting controller ...

The project uses a PIC16F684 microcontroller to control this LED chaser face wherein various patterns are followed by the LEDs. Different patterns can be made and added with the help of the SMD ...

Frank Hertel’s project: three individually dimmable LED lights. (Frank is the master of recycling; the wooden mounting pedestals are the panels from a decommissioned ATI console!) Thanks for your ...

Peter Griffiths - the man who made a lamp into a work of art and turned to LEDs for F1 gantry start-lights - returns with some LED chasing. This neat little circuit provides 8 LEDs directly driven ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...
