I am trying to make a small strobe project using an LED. I need the LED to flash at a fast rate (about 10 times per second). I can also use two or more LEDs instead of just one to get the same effect if that is possible. What is the easiest way of doing this? Thanks,
-Mike

 

10 Hz flash rate would be ideal for a 555 timer. You may have an issue with the current sourcing/sinking capability of the 555, so an external transistor would be needed on the output. You would connect the LED's anode to Vcc, and cathode to a resistor (small value) which then connects to the collector/drain of the output transistor.

A decade counter may be another idear, or even a microcontroller if you want to get fancy.
