In the previous chapter, we learned about "functions," which allow us to give names to groups of processes. This time, we will learn how to make the Arduino remember its current state. Let's try ...

In the previous chapter, we learned about "arrays," which allow us to handle multiple values as a single group. As programs get longer, the same processes appear repeatedly, and it becomes difficult ...

ESPHome is the sole reason I was able to build several ESP32 smart sensors without losing my patience ...

Have you ever wanted to build your own IoT-based Weather Monitoring Station? Imagine monitoring real-time temperature, humidity levels, atmospheric pressure, rainfall detection, air quality index (AQI ...

Thanks to software frameworks and libraries that have become quite powerful over time, even with a compact and inexpensive system, it is possible to achieve complex functions. In this project, we use ...

The scanNetworks method can be used to survey what access points are available. It returns the number of APs available. This in itself isn’t of much use, but behind the scenes it fills in a table of ...

Overview: This section explores the fundamental concept of functions in programming with the ESP32 using Arduino and MicroPython. Functions are essential for organising code into reusable and ...

The following project is an update of Gary D. Patterson’s “Simplified CTC signals” in the July 1988 issue of MR. Bringing the project up to date was a large endeavour. The block control project now ...

If you’re new to Arduino and connecting Arduino to the internet, the process might seem complicated at first. Many beginners face challenges when it comes to internet connectivity while coding with ...
