After building and exploring in Minecraft, I chose this sticky piston mob grinder to learn about redstone - which may have been a bit too ambitious, as I'm having problems with the loop which sends pulses to the sticky pistons.
I have set it up like this, and the circuit lights up when I step on the plate, and stays on constantly when I step off, until I break it by removing some redstone.
What I think should be happening when I step on the plate is that the circuit should activate, sending current round the loop, each time round sending a pulse out to the sticky pistons (which I'm fairly sure are wired up correctly, as they do move when they receive current) - and that this should continue, even when I step off the plate.
I've been fiddling around with this for 2 days, and just cannot figure out what I'm doing wrong. Any thoughts would be much appreciated!
