If anyone feels up to it, I would like to see a 555 timer circuit to compare with mine. Unfortunately, I seem to have messed something up, seeing as I blew an IC and a transistor this morning.
I need a time of 5 μs, so the timing capacitor is .01 μF and the resistor is 460 ohms. The timer is used for an array of LEDs. The LEDs draw 140mA, and eventually I need to get them to 1000mA. I had no resistor between the NPN transistor and the output of the 555, so I'm assuming that's why my transistor literally blew up and my 555 fried.
Please don't give me a link to the 555 section or LED section, I've read them enough to know that reading them again isn't going to fix it. I think I just need to see the circuit made properly before I ruin any other components.
Thank you in advance to anyone willing to help.
