This allows you to send and recive redstone!
To use more than one, replace all the recive with recive0, and send with send0.
For another, replace revive with recive1 and send with send1 in the command.
And for more, continue that.
Problems: Can only send to a redstone dot
Fix: place a observer on top of the redstone, running into a t-flip-flop (or a sideways facing sticky piston with a redstone block on it's face)
Also, it send a signal strength of 15.
If you have a improvement to make to this command, please let me know in the comments.
also, for whatever reason, I can't help but say that I typed the command by hand.
