ok im having trouble wirinng my 7555 chip, and figuring out the
capaictor,, i wish to run 4 led off 7555 which works when i/o pin 13
of my bs2 tells it to , i plan a mercury switch to tell i/o 13 to
turn on or off, so how do i wire the 7555 inorder to make 4 led
orange ones that come with kit, blink aprox every second 1 sec on 1
sec off, ive read the schematics ive found on 7555 , which is cmos
version of 555. and can get 2 lights to light up and stay on i
suspect my capacitor was issue, if i unpluged the cap light went off
but if i pluged it in it stayed on i used a 1 mfd cap, (which is 3
years old off a breasdboard)
so what im asking for again,,
how do i wire up 4 led, orange ones from paralax kit to 7555, to
blink every second for one second on one second off, and how do i
figure out the math for next time
how do i connect it to bs2 inorder to have a mercury switch turn it
on i/o pin 13 is the mercury switches output
