I'm bored alright?... See Inside and replace the "Buffer" block with any logic gate block! Press 1 to set input a to 1 Press 2 to set input b to 1 Letting go will set them to 0 Buffer: Input A - 1 | Output - 1 Not: Input A - 0 | Output - 1 Input A - 1 | Output - 0 And: Input A - 0 | Input B - 0 | Output - 0 Input A - 0 | Input B - 1 | Output - 0 Input A - 1 | Input B - 0 | Output - 0 Input A - 1 | Input B - 1 | Output - 1 Or: Input A - 0 | Input B - 0 | Output - 0 Input A - 1 | Input B - 0 | Output - 1 Input A - 0 | Input B - 1 | Output - 1 Input A - 1 | Input B - 1 | Output - 1
