Oscillator Relaxation

[madamerotten]

The unijunction transistor symbol lead with the arrow is called the "emitter," the other two leads are called "base one" and base two."

Do you want them sequential or all at once?

This was a reply to a pretty specific question. If what you want is just to flash some leds, there's a chip designed specifically for that and all it takes is the chip and a capacitor or resistor to drive a large number of leds. If you want to drive them sequentially then I would suggest looking at an lm3914 bar graph and put one of these oscillators on its input and bammo, you got ten leds zipping back and forth. Plenty of info here on either one.
