Okay, so be prepared - anyone with an iq above 10 will be going
or
within a few lines of this question, but im a at loss, and need some help here.
I have an alarm on my moped... so far so good. I want to make a red LED flash, like on cars, to show the alarm is active. I want it to blink for like 10ms and stay off for like 2 sec or something like that (didn't calculate the exact values yet). I'm using an astable configuration, with a diode going across R2, to get a lower duty cycle than 50%. Everything seems to be working BUT the led dosn't shut completely off, it dims to about 10% maybe. Why is this, and how to fix it? I tried using higher resistors, and running at 5v and not 12v, but it still dosn't turn off... I must be missing something.
I have it set up like this.
