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!
Today we will look at the Arduino IoT Cloud, an online application for building Internet of Things (IoT) devices.
I’ll show you how to get an account set up, how to configure your workstation, and how to build your first “Thing”.
The cloud was recently updated, so now even free plan users can work with the ESP32, and I’ll show you how to do that as well.
Learn to use common GPS positioning modules in your Arduino and Raspberry Pi projects.
Today we will see how satellite positioning systems work, and how to use GPS modules in our projects.
We’ll also build a GPS Logger to track our movements, then display our data on Google Maps.
The much-anticipated Arduino Nano RP2040 Connect board has a Raspberry Pi RP2040 MCU with ESP32-based WiFi and Bluetooth. The board also sports a 6-axis IMU with Machine Learning, a built-in MEMS Microphone, and a Cryptographic Coprocessor.
Today we will learn how to set up our development environment to work with this exciting new board, and we’ll run a few Arduino-supplied example sketches.
In order to learn to code in MicroPython or CircuitPython you are going to need to get a firm foundation in Python.
In this article I will give you a list of resources like websites, YouTube videos, Udemy courses and books that will help you become an expert in Python.
And the best part is that all of these resources are completely free!
