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.
ESP32 timer interrupt the easy way
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.
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.
TSAQM – The smallest air quality monitor
TSAQM – The smallest air quality monitor. It is an Arduino gadget based on the Attiny85, which uses na AGS10 sensor to assess air quality.
Amazing gadget with ESP32
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…
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”.
ESP32-C3 internal temperature sensor with Arduino
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.
Control LED brightness the fancy way
Learn how to control the brightness of an LED with feedback from a sensor. It is called an LDR, light dependent resistor and brings control to your LED.
Generate random numbers with ESP32
Have you ever needed to generate random numbers with ESP32? then this post is for you. We will use ESP32’s built in capabilities to create random number.
Random blinking lights with ESP32
Let us program random blinking lights with ESP32, using the Arduino random() function and two 5mm LEDs. ESP32-C6 and Arduino IDE.
Indoor weather station with MQTT, V2
I just created and Indoor weather station with MQTT, V2 with ESP32, ENS160 and BME280. Programmed with Arduino code and using Adafruit.io
Algorithm to LED blink with microPython
I will show you how to implement an Algorithm to LED blink with microPython, using the Raspberry Pi Pico 2 and Thonny IDE.
Master Buttons and LEDs with microPython
Learn how to control buttons and LEDs with microPython, not using any delay (time.sleep()), making non-blocking code Raspberry wit Pi Pico 2
Track Anything with Confidence: An Easy ESP32 GPS Guide
I will teach you how to implement a GPS tracking with ESP32-C6, using softSerial and showing data on Arduino IDE’s serial monitor
