Hello all, First my name is Ziad Ahmed Amer, I am from Egypt, I am 12, Today, In this world, you will see the most common command used to send a redstone signal to a lamp, I have dug the blocks under the command blocks so that u will know that I didn't connect them, click on the command block to know what is in there ;)
Way to do
Place a command block, and place and activator( lever, button etc.. ) and set the command to "setblock <x> <y> <z> redstone_block" the x y z must be the co-ordinates of the block beside the thing u wanna send Wi-Fi to, this will be the "enabling block", the disabling block will be the same thing except "setblock <x> <y> <z> air" the co-ordinates will be the same as the first one, so that when u activate the first one, it places the block near the redstone u want to activate, while the other one replaces the block of redstone to air which doesn't send signal which deactivates it( deactivates the redstone and Wi-Fi ) ;) 5 downloads for the redstone 8-bit screen which can be edited ;)
