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.
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!
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.
LiPo batteries are incredible powerhouses, they have a higher power-to-weight ratio than any other type of battery.
But with all that power comes a number of safety concerns, and not following them could lead to a deadly LiPo fire.
Today we will learn how LiPo batteries work, how to charge, discharge, balance, store and dispose of them. And, just in case, we’ll see how to extinguish a LiPo fire.
Today we will learn about electromyography by working with a MyoWare Muscle Sensor.
We’ll see how to use this device and its shields in both stand-alone mode and with an Arduino.
Today we will look at a powerful yet inexpensive machine vision sensor, the HuskyLens.
This amazing little device is based upon the powerful Kendryte K210 processor and is capable of adding machine vision capabilities to your projects.
The JSN-SR04T and A02YYUW are a couple of inexpensive waterproof ultrasonic distance sensors. They are easy to use, and have several advantages over the popular HC-SR04 sensor.
In this article I’ll show you how they work and how to use them with an Arduino Uno.
Today we will learn how RC Remote controls work, and how we can use them with an Arduino.
After learning two different ways of interfacing with the Flysky receiver, we will build a small robot car.
Our car will have two different modes – Normal & Spin. You’ll have to read the article or watch the video to find out what that means!
