Can someone please help me out here? I am trying to build a flashing LED using an ultra bright LED. I am getting conflicting results from various online calculators.
I am using an NE555P and trying to drive an ultra bright 3.4V 20ma led from a Vcc of 12vdc. I want the led to flash at a rate of approx 600 times a minute to emulate machine gun fire. Will the below circuit with the values of RA 56K, RB 56K, C 0.001uF and LED resistor 470R work ?
I would also like to be able to drive 12v solenoid from the timer with the option to activate the solenoid at the same time as the led and also opposite timing to the led.
