A lot of engineering students know this feeling. The code uploads without any error, the laptop says everything is fine, and then the actual project does almost nothing. The motor does not spin. The sensor value jumps around. The board resets for no clear reason.
That is usually when the real lesson starts. Good engineering is not only about writing code. It is also important to know what the circuit is doing when the code reaches the board.
Code Can Look Right While the Hardware Fails
Most small engineering projects need code now. Arduino, Raspberry Pi, ESP32, and STM32 boards all depend on it. But the code is only one part of the project. Once it reaches the board, the wiring, power, and parts all have a say too.

Connecting inexpensive edge hardware to robust cloud architecture is the foundation of modern engineering projects. The ESP32 microcontroller has become a staple for developers due to its integrated Wi-Fi capability and low price point. However, capturing data locally on your workbench is vastly different from streaming data securely to an enterprise cloud system.
While this tutorial will help you build a functional prototype on your workbench, companies looking to securely deploy thousands of these IoT nodes across a smart factory often team up with a Microsoft solutions partner to architect a highly scalable and secure Azure environment. For our purposes today, we will focus on bridging the gap between physical hardware and the cloud by settin ...
