Module Duration: 2 sessions (30 minutes + 90 minutes)
Module Objectives:
This module aims to help students understand the integration of IIoT-enabled 3D printing services with blockchain technology, focusing on the connectivity between the Raspberry Pi and smart contracts deployed on a local blockchain network. Students will be able to connect these components using the Ethers.js library, implement decision-making logic based on smart contract data, and conduct comprehensive testing to ensure the system functions as designed, from blockchain transactions to initiating physical printing processes.
