There is one component, rx, which has no outputs (and is of the bespoke Output component subclass). The explanation is going to be longer than the code, I think. Print ('Part 2:', lcm(*feeder.input_flipped.values())) So this essentially tests to be sure your circuit is working for part 2. Part 1 wants us to press the button a thousand times and determine the product of the high and low pulses that were sent by any component. We count the number of high and low pulses, because that is what part 1 wants. We loop, sending pulses to components, until there are no more.

We start things off by sending a low pulse to button, which will pass it along to the broadcaster and get the party started. Signals are sent by adding them to the pulse_list, something every component can do. It lastly connects the button and the broadcaster together.ĭef push_the_button(component_dict: dict, counts: dict):Ĭomponent_dict.pulse_in(None, State.LOW, pulse_list) First pass creates the components, second pass connects the inputs and outputs. button isn’t in the puzzle input, so I add it explicitly. read_data first makes all the components. Today’s was pretty long, so not going to put in all the code, like the component classes. # Connect button to broadcaster as a special caseĬomponent_dict.add_output(component_dict)Ĭomponent_dict.add_input(component_dict) And this was definitely going to be implementing an adder.Ĭreate_component(ins, name_dict, component_dict)Ĭonnect_components(ins, outs, name_dict, component_dict) I was going to need to make a common component class and subclasses for the different behaviors. The problem description was pretty clear. Pressing the button fills up the queue and this continues on until the queue is in a settled state, at which point, the button can be pressed again. All components, including the button, send their pulses by using a FIFO Queue (first in, first out). Pressing the button sends a pulse to the broadcaster. A flip-flop switches its state when it receives a low pulse and passes that along to its outputs.A conjunction saves the last pulses sent by its inputs and when the saved values for all its inputs are high, it sends a low pulse to its outputs.

A broadcaster takes a pulse from input and sends it to all its outputs.A button sends a low pulse to its outputs.There’s a few components you need to use: The elves don’t have much to do today, as the puzzle wastes no time getting to the meat: it wants you to build a digital circuit, and then run it.
