Introduction Today we will take a look at using a rotary encoder with Arduino and displaying rotation data on the Nokia 5110 LCD display. A rotary encoder is an electro-mechanical device that converts angular position or the rotation of a shaft into analog or digital values. They are mainly of two types, absolute and incremental rotary encoders. The output of the absolute encoders indicates the current posi ...

I have salvaged so many old lap-top batteries ( 18650 ) to reuse them in my solar projects.It is very difficult to identify the good cells in battery pack.Earlier in one of my Power Bank Instructable I have told, how to identify good cells by measuring their voltages, but this method is not at all reliable.So I really wanted a way to measure each cell exact capacity instead of their voltages. Few week ago, ...

In this project you’ll create a standalone web server with an ESP32 that can toggle two LEDs using the Arduino IDE programming environment. If you want to learn more about the ESP32 dev board, read my Getting Started Guide with ESP32.  First, watch the video demonstration below Preparing the ESP32 board in Arduino IDE There’s an add-on for the Arduino IDE that allows you to program the ESP32 using the Ardui ...

This is a simple guide that will teach you how to get started with this cheap Arduino mini clone, covering all the steps one should do to make it work. Basically they are 4... Soldering PIN headers* Wiring it up Installing properly drivers** Testing ..and this is the minimum required that you need to follow this guide: BTE13-010 (328p 5V 16Mhz - Arduino mini clone) CH340G (Serial_to_USB converter) Connector ...

With all the different ways capacitors are labeled, figuring out the values of your capacitors can be challenging. Especially if you don’t have a digital multi-meter to test them. In this tutorial, I’ll show you how to build three different capacitance meters using an Arduino and a couple resistors. After finishing this project, you’ll be able to measure all of your capacitors and label them for future refe ...

In this tutorial, I’ll explain how to set up an LCD on an Arduino and show you all the different ways you can program it. I’ll show you how to print text, scroll text, make custom characters, blink text, and position text. They’re great for any project that outputs data, and they can make your project a lot more interesting and interactive. The display I’m using is a 16×2 LCD display that I bought for about ...

Dejan Nedelkovski had built an Arduino security and alarm system project that uses an ultrasonic sensor for detecting objects and a buzzer for notification. Components needed to build this simple system are: Arduino board, LCD display, 4×4 keypad, ultrasonic sensor and buzzer. The circuit can be connected as shown in the schematics below. In order to build the project, you have to connect the buzzer with a ...

The DHT11 humidity and temperature sensor makes it really easy to add humidity and temperature data to your DIY electronics projects. It’s perfect for remote weather stations, home environmental control systems, and farm or garden monitoring systems. In this tutorial, I’ll first go into a little background about humidity, then I’ll explain how the DHT11 measures humidity. After that, I’ll show you how to co ...

Have you ever been unsure which display you should be using in your next project? This tutorial from educ8s.tv will come in handy for choosing the best display for your each and every Arduino project! There are lots of choices, so let’s talk about each one of them. Basically, you have three types of displays: LCD displays, OLED displays, and E-paper displays. LCD displays: LCD (liquid crystal display) is th ...

In this project I will show you how you can make an Arduino Touch Screen MP3 Music Player and Alarm Clock. You can watch the following video or read the written tutorial below. If we enter the Music Player we can start playing the music by pressing the big “Play” button in the middle of the screen. Right beside it, there are two more buttons, for playing the previous or the next song. Above these buttons th ...

Protect your valuables with a puzzle! Things used in this project Hardware components Arduino MKR IoT Bundle × 1 Software apps and online services Blynk Story Keeping your valuable items away from prying eyes can be hard sometimes, unless you put it in a big safe or something similar... but who has room for that? Instead, create your own puzzlebox using the components from the MKR IoT Bundle and some cardbo ...
