This video made by me shows you how to build the circuit that I use for almost all of my redstone projects, if you need any help building this please just let me know. Enjoy!
That is a decent circuit.
When you need to do things repetitively.
When you make a "circuit" it usually is meant to do something more than once.
You don't need a "circuit" to do it once just use reds tone trail and a button/switch.
