Redstone Basics
Power levels, signal strength, repeaters, comparators
Redstone signal travels 15 blocks
Use repeaters to extend signal, each adds 1 tick delay
Comparator in subtraction mode
Place torch on side for subtraction, useful for inventory detection
Observer detects block updates
Outputs 1-tick pulse, use for instant farms and doors
T flip-flop toggle circuit
Single button press turns on/off, sticky piston with redstone block
Hopper timer for delays
Items moving between hoppers create adjustable delays
Zero-tick farms (patched)
Most zero-tick removed in 1.16+, use observer-piston instead
Logic Gates
NOT, AND, OR, XOR gates, T flip-flops, RS latches
