Hi All,
I have put together a basic LED flasher using a 555 and 4017 chips. It works just fine powering 4 yellow LEDs (alternating 3 pulses each). These are rated 20mA each.
I wanted to make it brighter and purchased 3 watt LEDs that are rated 700mA each.
My question is this...
What is the best way to power the larger 3w LEDS? Is it possible to increase the output of the 4017?
I borrowed an LED Driver (Velleman vm143/3w) and simply replaced the small 20mA LED with the driver and connected it to the 3w LED... as Im sure you guessed... this did not work. The LED is very dim.
Any suggestions?
SHould I scrap the original schematic and start from scratch? Can I use the same design (555 and 4017) but power 3w LEDs?
Im very new to this and enjoying learning and reading about it. Any pointers would be great!
Thanks again
