+## 2025.11.11
+
+### Added
+
+- Designed kernel and enhanced interfaces for the Artifical Neuron component
+- Created an abstract class for Neuron (NeuronSecondary), implementing both common and secondary methods
+
+### Updated
+
+- Changed design to include queues representing each set of weights and inputs
+- Fixed naming of interfaces to better match the convention
+- Changed some data types within methods in order to better execute the component's function

+I believe that the artificial neuron is the one that is the most interesting to me personally, and I also believe that, minus some need for research on machine learning algorithms, the component would likely be fairly simple to implement. At the most basic level, it essentially functions as a calculator; evaluating values based on a pre-set formula and outputting a result.
