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. The post ESP32 hardware interrupt the easy way appeared first on FritzenLab electronics .
Let's dive in the ESP32 timer interrupt, a way of controlling your programs that is simple and straightforward. We will implement the blink of two LEDs independently, without one interfering on another. The post ESP32 timer interrupt the easy way appeared first on FritzenLab electronics .
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. The post Which temperature sensor to pick? appeared first on FritzenLab electronics .
TSAQM - The smallest air quality monitor. It is an Arduino gadget based on the Attiny85, which uses na AGS10 sensor to assess air quality. The post TSAQM The smallest air quality monitor appeared first on FritzenLab electronics .
Let us make an e-paper display gadget with ESP32 and Arduino code. It will feature a SHT21 temperature and humidity sensor and currency conversion (you pick which one). Also there will be an Youtube subscriber live counter. The post Amazing gadget with ESP32 appeared first on FritzenLab electronics .
Have you ever had the need to use the BMP180 sensor with MicroPython? this post is for you. We will use a RP2350 microcontroller. The post BMP180 sensor with MicroPython appeared first on FritzenLab electronics .
We will implement a decorative WiFi binary thermometer, using WS2812b LEDs and an ESP32. Temperature in degrees Celsius will be shown in binary format in six RGB addressable LEDs. The post WiFi binary thermometer appeared first on FritzenLab electronics .
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". The post One button Arduino game appeared first on FritzenLab electronics .
ESP32-C3 has an internal temperature sensor, readable via Arduino code. All you need is a bit of code and the Arduino IDE serial monitor. The post ESP32-C3 internal temperature sensor with Arduino appeared first on FritzenLab electronics .
