I'm just starting on learning electronics, and made a 555 astable oscillator/pwm based off
h**p://www.sentex.ca/~mec1995/circ/pwm555.html
Rather than the transistor, motor R2 and Schottky diode i have 2 leds hooked up. One from V+ to pin 3, and one from pin 3 to ground. This flashes them alternately. But the led sourced from pin 3 fades up, rather than blinking on...
The only other change from the above circuit is a 10μf cap for C1, to adjust the frequency.
Basically, how can i get the second led to turn on sharply, rather than fade up?
Thanks for any tips...
