Programming the Arduino – Memory Management / Part 2

Let’s get started with the second part of the Arduino programming series. This time we’ll be talking about memory management on the Arduino, how to use it and how best to manage it – showing you how to free up memory and guidelines for programming that will help you reduce your memory footprint on the Arduino.

This article requires some basic understanding of memory, datatypes and basic C/C++ programming skills.

Programming the Arduino – Basics / Part 1

Since we post up lots of Arduino related content on the website, it only makes sense that we have some sort of tutorial series to follow. This will start from the basics to the more advanced subjects, hopefully expanding your knowledge of the Arduino.

The Requirements

  1. 1x Arduino Compatible Board (Uno, Duemilanove, Leonardo, Mega etc.)
  2. Windows Environment (We’ll be using Win 7 / 8)
  3. Knowledge of basic programming (e.g. knowing what a variable, function etc. is)

All of the program code will be compatible with all versions of the Arduino; all code will run within the Uno specification, as that is what we will be using. The tutorial series will include the use of some switches, LEDs, sensors etc. which will be mentioned in either the title of the tutorial or in the requirements section.

Creating a Spotify remote with an Arduino and LCD Shield

spotifyremoteThis one is for the Spotify people. We’ve created a small project that makes use of the Arduino and LCD Keypad shield to create a Spotify remote control. This will show the current playing song as well as adding Play/Pause, Prev and Next functionality to it.

Check out the quick YouTube video at the bottom of this page.

The remote is made from a VB.NET application that listens on a select COM port for commands, it also broadcasts the current playing song via the COM port to the Arduino.

You could add a Bluetooth module to this (described in our previous article here) to make it completely wireless, which would be really cool.

How to use WiFi with the Intel Galileo

GalileoOne of the best features about the Intel Galileo is that it has an mPCIe expansion port for adding various cards to it. One of the cards you can add is for connecting to your wireless network.

The steps below should get you up and running with connecting your Intel Galileo up to your network in the Linux environment and through the Arduino code.

Lets get cracking…

LANp – A DIY Arduino network controllable RGB lamp made from scanner parts!

IMG_20140322_162510This is something we have really been meaning to write up. A few weeks ago we ripped out an RGB LED from an old Canon Scanner that was laying around and going to waste. Since then we’ve been playing around with the RGB LED element and decided to put it to good use.

We have come up with LANp – This is an Arduino and Ethernet Shield that controls an RGB LED colour real-time with a Javascript colour picker.

Take a look below for the YouTube video of this working at the bottom of the page!

Let’s build a functional Arduino webserver with the Ethernet/SD Card shield

ardethernetIt’s that time of the week! We’ve been playing around with the Ethernet shield again and this time we’ve come up with an article about creating a webserver from scratch; using the Arduino SD/Ethernet Shield.

This article will show you how to serve files from the SD Card file system and use Javascript to get sensor/variable values via AJAX.

This would be ideal for people looking to add a basic web system to their projects.

MicroView: Chip-sized Arduino with built-in OLED Display on Kickstarter

oledWhilst browsing Kickstarter we came across these MicroView Ardunio’s which is an Arduino with a built-in OLED Display; as well as providing downloadable libraries for quickly displaying text, sprites, graphs and gauges on the OLED.

The Microview has already reached it’s pledge goal with 27 days remaining (at the time of writing this post)

We think it’s a really unique idea and it would be pretty fun to have one of these if you have a small project in mind that requires some sort of visual display.

Getting your Nokia 5110 LCD up and running on an Arduino

nokiaWe purchased one of these very cheap, very cool 84×84 LCD backlit screens off of eBay a couple of weeks ago.

It’s a very nice product for adding visual elements to your projects at a very low price. We paid ¬£3.89 for the screen and it was delivered a few days later.

Take a look below for connection instructions and example code from Adafruit on how to get this up and running with your Arduino.
