If your project needs a responsive user interface or has precision timing requirements, then interrupts are the key to getting it to work smoothly.
Today we will learn how to use Hardware, Pin Change and Timer Interrupts with the Arduino Uno.
Learn how to use one of the ESP32-CAM board’s most neglected features – the MicroSD card. In this article, I’ll show you how to use the MicroSD card to store photos taken with the camera.
We will also build a motion-sensitive and a time-lapse camera using the ESP32-CAM.
Learn how to use both 7-segment and dot-matrix LED displays with an Arduino.
We will be working with both single and multiple display units, in a variety of configurations.
LEDs are by no means dead, they are still a great choice for a number of applications. Add one to your next Arduino project.
ESP-NOW allows you to create a private peer-to-peer network between ESP32 and ESP8266 devices.
Today we will learn how to use ESP-NOW with a bunch of ESP32 boards. We’ll also build a remote temperature sensor, and expand it to have multiple sensors.
The Raspberry Pi Pico is a very powerful microcontroller, especially when compared to an Arduino Uno. Yet most of the time we reach for a board to test with, we pick an Uno! This is because the Uno is easier to prototype with.
Well, today we’ll change all that and build three different “Pico Uno” boards that have the power of the RP2040 and the ease of use of an Arduino Uno.
Stop hard-coding wifi credentials in your ESP32 and ESP8266 sketches – use WiFiManager instead!
This easy-to-use wifi provisioning library eliminates the need to hard-code wifi information, and makes your projects portable!
Learn how to use WiFiManager and how to easily adapt your existing sketches to eliminate hard-coding forever!
The 555 is one of the most popular integrated circuits ever created, with over a billion of them produced every year. In many cases, the 555 is a simpler and better choice than using a microcontroller.
Today we will learn how the 555 works, and then we will build five simple projects using a 555 timer.
Learn to use soil moisture sensors, both resistive and capacitive.
After calibrating our sensors, we will use them to build two projects. One of them is a soil moisture meter, the other is an automated watering system that uses the Arduino IoT Cloud.
Celebrate 10 years of the Raspberry Pi by building 10 unique Pi projects. Every model, from the Zero to the Raspberry Pi 4 and the Raspberry Pi Pico are included.
We’ll also cover the history of this amazing little microcomputer.
So come and join the party!
Balena Sound lets you use a Raspberry Pi to turn your old stereo system or amplified speakers into a wireless sound device.
It works with Bluetooth, Apple Airplay, and Spotify Connect.
You can even use Balena Sound to build a whole-house audio system!
