Hey! Aris9834 here! Today I will show you how to be a good redstoner. So you will need redstone repeaters to keep the redstone going.
0 = redstone. X = repeater

0000000000X0000000

Or if u want to make a piston door use redstone torches.
Well, im not good with command blocks.

Or you can make up your own way.
You can use this way for other things such as TNT, redstone lamps, dispencers, and more!
