Learn about 7 segment displays with its pin diagram, description, datasheet, its working, types of 7 segment displays and how to select a 7 segment display.

Big, Auto Dim, Room Clock (using Arduino and WS2811): First Hello instructables. This is my first contact with : Instructables Arduino Programmable LED'sSo please don't trow rocks at me for noobish mistakes. Keeping that in mind I'm waiting to read your comments with grate interest and I'm open to any …

Setup a simple web server with the Arduino.

How to Build an L293D Motor Board Controller for Arduino: I am working on a small robot that can be controlled by an Arduino using wireless communications. But I was discouraged by the number of wires running from the Arduino and the breadboard. So I decided to reduce the number of wires by making my own …

How to Capture Remote Control Codes Using an Arduino and an IRreceiver: In this instructable I will show you how to write a small code to capture the remote control codes in Hexadecimal and decimal values.We will do this using the serial monitor that is embedded in the Arduino IDE.This will introduce you to a library ca…

PCB etching is another big topic in the electronics DIY world. It's something every electronics tinkerer ends up trying sooner o later. Even thou it's a fairly simple procedure it requires some self confidence (or bravery) since it involves strong, smelly and hazardous chemicals. Any etching procedure you read about can be described in 5 different steps: designing, transferring, etching, assembly and reuse or disposal. For every one of these five steps there are different options and there…

Stop Using Ferric Chloride Etchant! (A Better Etching Solution.): Ferric chloride is a traditional home-use circuit board etchant. It's easy enough to come by, and the Ferric by itself is no big environmental problem. However, once you've etched a board with it, you're left with a solution with a bunch of coppe…

Arduino Nano Based Microbot: This instructable was created to be entered in the Robot Challenge. If I win, the parts will of course, go into robots like this one. Notes on how to include some of the very components in the prize packages are given in the last step. I am 28, so o…

$1 Motor Driver Circuit for Arduino: The story of this motor shield is that I wanted to make a robot for my multifunctional brainwave controlled system and I decided to share this with you. It's a very simple circuit I used the L293D IC that is a dual bridge motor driver IC. I also add…

The Beginner’s Guide to Display Text, Image & Animation on OLED Display by Arduino: In this article, we’ll talk about OLED displays story and their differences, how to run them by simple controllers and display text and images on them. At the end of this article, you will be able to:Explain OLED display theoryRun OLED displays by …

In this review, I thought I would combine Adafruit's 0.56" 7-segment LED backpack and display and their DS1307 RTC (Real Time Clock) board. The obvious choice for such a combination is to make a simple clock! Note that my pictures make the display look a little washed out. It wasn't, it was very bright. This is juts an effect of my photography lighting setup being even brighter. Both modules are I2C and therefore just require two data pins along with GND and 5V. So, for anyone who has done…

ARDUINO SOLAR CHARGE CONTROLLER ( Version 2.0): [ Play Video ]One year ago, I began building my own solar system to provide power for my village house. Initially, I made a LM317 based charge controller and an Energy meter for monitoring the system. Finally, I made a PWM charge controller. In Apri…
