Why do you think a 9V circuit will electrocute the user?
Btw, the LEDs should have current-limiting series resistors.
Why do you think a 9V circuit will electrocute the user?
Depends on how sensitive the LEDs are and how bright you want them to be. A CD4017 can source only a few mA. A 74HC4017 can sink a higher current. Which one are you using?how many ohms should the resistor be?
You can get way more than 2mA. The current specified in the datasheet is for the output voltage to be within the valid prior voltage range
Thanks guys for all your responses!
Herschel Peeler the trigger i want is the actual game, the steady hand game. Like this:
View attachment 29086
How can i do this?
What metal should i use?

This is more difficult. I would use a piece of wooden dowelling or broom stick.
I have the facilities to slit the dowel down and cut a groove in one side, then glue back together. Long drills are available but are expensive and difficult to hold to run down the center.
How far are you from Whatstandwell (Crich)?
Guys why is that when i add resistors (as current limiting resistors for the LED's) on the electronics software application, that they don't work?
