Is there a better way, with minimal components to blink LED L1 when control pin pulled LOW via an Arduino ?
It can be byredrawing it to be active HIGH which i don't wish to. I was thinking of using this Logic NOT gate to invert the signal and with a feedback from pin 4 via the resistor and cap C3 i could blink the LED. First time with logic gates so, does logic gate default to LOW when powered or is it HIGH at the output ?
