Crazy Multicolor Flashing LED Globe!

Crazy Multicolor Flashing LED Globe!

Nowadays, single-color and multi-color flashing LEDs are easily available, which obviates the requirement of external chips to produce fascinating lighting effects. What can we do with one piece of such a single color flashing LED, and two pieces of multicolor flashing LEDs? Here is an ultrasimple circuit of an LED Globe wired around the evergreen timer chip IC 555. One advantage of this LED Globe is that it is a voltage-controllable flashing device, ready to work together with any microcontroller chip. This allows you to control the light pattern to a certain extent in tune with the output signal from an external microcontroller, too!

Schematic of the Multicolor Flashing LED Circuit

Note

Set jumper J1 in open position when you are using an external control voltage
R2-C2 values used here is not very critical. Start your own experiments with various values
If you want to use multiple LEDs at the output, try to use suitable driver circuits based on bipolar transistors/mosfets
If you have another simple solution for achieving this effect I’d love to see it. Please use the comment box
