Hi, I am new here, and I was hoping you guys/gals can help me in a small circuit. I made a flashing LED circuit as per this circuit diagram from this site. http://www.kpsec.freeuk.com/projects/flashl.htm I works well. But I want to place a Nichrome coil replacing the LED and it should glow. I tested the Coil directly with 6 volts, and there was enough amps to heat it up and make it glow. When I placed this in the circuit replacing the LED(and removing the 470 ohm resistor), it wouldnt heat very much enoguh to glow (the heat was very small, nearly neglegible). And also i think it is damaging the output pin on the 555 Timer. Can someone help me with my circuit, or am i taking the wrong approach? If so, can you show me the right circuit. Remeber I need the circuit where I can adjust the duty cycle.:) Thanks for any help.
