Fingerprint Sensor with Arduino

How to use a fingerprint sensor with Arduino If you want to add biometric security features to your Arduino projects, an easy way to do so, is to add a fingerprint sensor module to it. In this video we demonstrate how easy to use a fingerprint sensor with an Arduino Nano and a small display. [...]

Arduino 3.5″ Color TFT display ILI9481 on Arduino Uno and Mega tutorial

In this video we learn how to drive the new, low cost big, Arduino 3.5" Color TFT display and we learn how to use it with the Arduino Uno and Mega. A few weeks ago, I discovered this Arduino 3.5" Color TFT display on Banggood.com and thought that it might be useful in [...]

WeMOS D1 ESP8266 vs Arduino Uno, Arduino Due and Teensy 3.2. Which one is the fastest board?

In this video we are going to compare the computational speed of the WeMOS D1 ESP8266 based Arduino compatible board with the computational speed of the most popular Arduino boards and the Teensy 3.2. We can call this video ESP8266 vs Arduino! Let’s get started! A few weeks ago, in a similar video [...]

Arduino Tutorial: Serial Plotter – How to use it

A few months ago, with version 1.6.6, the Arduino IDE introduced a great new feature. It is called Serial Plotter and you can find it in your Arduino IDE under the tools menu. Using the Serial Plotter we can graph the output of our Arduino project in real time. The Serial Plotter is [...]

Arduino Tutorial: ESP8266 OTA. Update the WeMOS D1 Over the Air (OTA).

In this video we are going to see how to wirelessly update the code of our Arduino project, using the WeMOS D1 ESP8266 based board. We are going to perform an update to the ESP8266 OTA. This is an impressive, and very useful feature. If you want to see how to update your ESP8266 board [...]

Arduino 433MHz RF tutorial with DHT22

Do you want to see how to establish a communication link with Arduino? In this Arduino 433MHz RF tutorial we are going to build a simple project just to demonstrate how easy it is to add wireless capability to our Arduino Projects with these 433Mhz modules. I have two Arduinos here. This one is sending [...]

Arduino Real Time Clock and temperature Monitor with 3.2″ Color TFT display

In this video we are building an Arduino Real Time clock and temperature monitor with a big 3.2" Color TFT display. We are using a DS3231 Real Time clock module to get the time, the date and the temperature. The heart of the project is the powerful Arduino Due board, which can drive the display [...]

Auto Power Off Arduino – Simple circuit

In this video we are going to see how to make Arduino power off itself with the help of a simple circuit! Let’s start! If you have watched some of my previous videos you will know that I like my projects to have minimal power consumption so that we can use them with [...]

Teensy VS Arduino – Which one is faster?

I wanted to find out if Teensy 3.2, despite its small size, is faster than the Arduino Due, the fastest Arduino board available today. So I build a simple project where both boards run the same sketch, the Newton's approximation of Pi for 500.000 iterations. Which one is faster? The board that finished first. Teensy [...]

Arduino 4W COB LED Tutorial

Arduino 4W COB LED Tutorial High Power LEDs are very popular and low cost nowadays so I thought it would be a good idea to learn how control them with Arduino. So, I built a simple project that simply turns on a 4W Cob LED when the button is pressed. When the button is pressed [...]
