Embedded Systems
Never heard of Zigbee? By the end of this guide you will understand it completely — device roles, mesh routing, the stack, clusters, security and battery life — and you will have built a real, working Zigbee sensor network whose data flows into MQTT.
Embedded Systems
The complete, practical guide to Industrial IoT — from sensors and the ESP series to protocols, edge computing, data, security and predictive maintenance. By the end you will understand the entire IIoT stack and have built a real, connected industrial node yourself.
Embedded Systems
Know nothing about OPC UA? By the end of this guide you will understand it deeply — servers, the address space, nodes, subscriptions and built-in security — and you will have built a real, working OPC UA server and client in Python, ready for industrial use.
Embedded Systems
Know nothing about MQTT? By the end of this guide you will understand it deeply — brokers, topics, QoS, retained messages, security — and you will have built a real, working project with command-line tools, Python and an ESP32.
Embedded Systems
From hardware roots of trust and cryptography to TLS, secure firmware updates, key management and IEC 62443 — a deep, practical dissection of how to make embedded communication genuinely secure, from zero to expert.
Embedded Systems
From RS-485 and Modbus to CAN, OPC UA, MQTT and cellular IoT — a deep, practical guide to every layer of embedded communication, and the proven ways to make a decades-old machine speak to your network.
Embedded Systems
Most factories still rely on machines built long before the internet. Embedded systems are the fastest, most cost-effective way to give that legacy equipment network connectivity, remote control and real-time monitoring — without replacing it.
