A multimeter is a must-have tool in your arsenal when it comes to creating or developing electrical circuits. Without it, executing a job will be extremely tough. So, in this video, we chose to create a low-cost digital multimeter using Arduino and other basic components.

This tutorial is focused on bringing out all the different types of Arduino development boards and doing a quick comparison of their features and applications so that you will be able to make a better choice when you want something more than the popular UNO and nano boards.

In this project, we will make a sun tracking system which will help the solar panels to generate maximum power.

In this tutorial, you will learn how to create an Arduino based smart door lock; this smart lock has the ability to be unlocked by your cell phone. At the end of this project:

You will learn how to generate a specific QR code.
You will learn how to create a login page by ESP8266.
You will be able to unlock a door using your cell phone

The 16x2 is the most commonly used LCD display module. It can display 16 characters in a column for 2 rows thus a total of 32 characters. The characters can either be number, alphabets or symbol.

Power consumption is a critical issue for a device running continuously for a long time without being turned off. So to overcome this problem almost every controller comes with a sleep mode, which help developers to design electronic gadgets for optimal power consumption. Sleep mode puts the device in power saving mode by turning off the unused module.

In these steps I show you how to simply control a GoPro Hero 4 and a GoPro Hero Session 5 using an Arduino wifi board. As you will learn, these instructions could easily be adapted for any type of GoPro.

The Arduino MKR1000 stands for “Maker 1000”. This small form factored board by Arduino is aimed at building IOT projects since it comes with an on-board Wi-Fi feature. It also runs on 32-bit architecture making it faster and more reliable with encryption features.

It's a known trick that we can use LEDs in reverse. We'll explore how to use them as photodetectors with Arduino and create a simple demo that responds to hand swipes.

Get started with your very first Arduino project by making an LED light blink on and off. We'll look at how you can modify your project and show some future applications that we can build from this solid starting point.
