Simple Infrared PWM on Arduino, Part 2- RAW IR Signals

AnalysIR Blog, Arduino, , , , , , , , ,

In Part 1 of this series, we demonstrated how to send signals using simple Infrared PWM on Arduino. In this Part 2 post we look at sending RAW IR signals – specifically a RAW NEC signal and a longer RAW Mitsubishi Air Conditioner signal. We have also improved the method shown in Part 1 due to some issues we identified when sending ‘real’ signals versus the ‘test’ signal we used before. (More on that later). In Part 3, we will take the signals from this post and show how to send them using their binary (or Hex) representation, which saves lots of SRAM.

Custom TV remote control using Arcade style console

  Following on from our previous blog post about SKY+ RC6 IR codes, we have now completed the project and are about to ship to its new owner – a friend of ours.

SR1We purchased a Sega megadrive Arcade style games console which was BNIB for €25 ($35) and disabled all of the built-in gaming functionality. We then wired up each of the 12 available switches (Joystick & Arcade style buttons) to the Arduino Nano which was placed onto an Arduino prototyping shield and mounted to the enclosure using ‘lots’ of hot glue. Note some of these consoles come with an additional 2 buttons, which can bring the total to 14. In addition, the joystick has 8 positions in total of which we used only 4 as it would be too difficult for the user to manage all eight.

New infrared applications using Arduino at Mini MakerFaire Dublin (tomorrow!)

AnalysIR

Here is an extract of the Arduino blog post featuring AnalysIR. Click the the link above to visit the Arduino Blog.

The power of infrared light was widely and best appreciated with invention of television’s remote controls. The signal between a remote control handset and the device it controls, consists of pulses of infrared light, which is not visible to the human eye.

Tomorrow at MakerFaire Dublin you’ll we able to see the work of AnalysIR, a project that is taking this technology to a whole new level.

They implemented a Windows application which connects to an Arduino with the addition of an IR receiver and can decode new IR signals in a fraction of the time: no need for expensive Logic Analyzers or Oscilloscopes.

Here they are with their Indiegogo campaign:

At MakerFaire they will be showing some cool demos of what you can do with IR like generating electricity, seeing the invisible -Using iPhone & Android camera to check if TV remote is working, long range TV remote Control Demo Using Optics and many more applications for a total of 10 installations. Look out for them on Saturday!
