TGS2602 air quality sensor on a breadboard

TGS2602 air quality sensor – odorous gases

Let me present you a small yet powerful sensor, capable of assessing air quality. The TGS2602 is capable of reacting and detecting odorous gases like ammonia and hidrogen sulfide.

ESP32 hardware interrupt the easy way

Using the ESP32 hardware interrupt is a piece of cake, given you know the right commands to use. Let us dive into that and learn how to harness hardware interrupts the right way.

four temperature sensors comparison

Which temperature sensor to pick?

Today’s post will be all about temperature sensor comparison. I have picked four different ones to show you how they behave and function. We will learn how to interface them to Arduino UNO and ESP32.

ESP32 and push button on a breadboard

One button Arduino game

In this post we will implement an one button Arduino game, using exactly one button, one ESP32 and Arduino IDE. The ideia is to implement a game that I call “one second game”.
