How to classify data with a Perceptron Neural Network? [closed]

I created a perceptron neural network to understand the concept well. My goal would be to define what an orange is, by its numbers of chemical elements and what is an apple by the same formula. Is it a neural network of just one layer , would I have to use a multi-layered network to perform this process? Could anyone show a practical example? It would be nice to talk a bit about.
