Driving an Infrared Led directly from an Arduino Pin

logobutton200x200A common question asked on forums is one about – Driving an Infrared Led directly from an Arduino pin.  Although the answer may be obvious to anyone with at least a basic knowledge of Ohm’s Law, many are confused about how to choose a resistor value for optimum performance. Often, there is a debate about whether a resistor is required at all, given that the AVR pins are rated to deliver an absolute maximum of 40mA on a pin. (Note: All of the quoted specs in the data sheet are for test conditions of up to 20mA on a pin). Of course there are better ways to drive an IR LED with a transistor circuit or even a constant current circuit. However, in this post we consider only the direct drive circuit using a current limiting resistor, as illustrated in the diagram down below.
Make sure to read the caveats at the end of this post.

Video: AnalysIR Demo Batch Infrared Decoding

Here we show a screen capture demonstration of the ‘Batch Decoding’ feature of AnalysIR. We show Infrared signals from 4 different Air Conditioners and how we can load them into AnalysIR and execute a batch decode of all of the signals in one easy step. Included are signals from Panasonic, Vestel, Fujitsu & Daikin

AnalysIR now decodes 40 Infrared Protocols

We have been updating the AnalysIR documentation for the upcoming 1.0 release and realised that AnalysIR now decodes 40 Infrared protocols. Wow!. Along with the most common TV & media remotes controls there are 15 Air Conditioner protocols included. The full set of protocols is included with the latest ‘dev’ release, which is available to all current & new owners of AnalysIR (less the aforementioned documentation) in advance of the  pending 1.0 release. The 1.0 release will incorporate over 170 new features, updates and fixes compared to the initial release and also supports our new IR Learner which will be launched along with a range of Infrared kits in the coming months.

Teensy now supported for AnalysIR

A new user of AnalysIR from the Netherlands, wanted to get the AnalysIR firmware working on Teensy 3.x . Although this has not been officially supported, we were happy to support his efforts knowing that it would most likely be a relatively easy exercise, based on past experiences. Needless to say, he was successful in decoding Infrared signals with AnalysIR within a short space of time. Prompted by his interest, we ordered our own Teensy 3.1 to add to our growing collection of 40+ MCUs and although Teensy support is in beta for now, it will be oficially supported for AnalysIR from our next release. In the meantime, users of AnalysIR can just contact us for a copy of the Teensy sketch (firmware).

Controlling Chigo Air Conditioner via Infrared from smart phone

Anyone who has tried  controlling an Air Conditioner unit using an Arduino, USB IR Toy, RPi or any MCU will know how difficult it can be to record the longer infrared signals they use. Typical TV systems use IR signals circa 32 bits long, while this Chigo AC unit uses a signal with 197 marks & spaces (or 97 data bits). One of our users, Sertunc – from Istanbul in Turkey, reported his success using AnalysIR to easily record the signal timings for his AC unit and sent us the details along with some nice photos. After testing the validity of the recorded signals using an Arduino, he then set about loading the signals onto his Samsung smart phone (models S4, s4 mini, S5 and more supported). This was helped by installing the free ‘Samsung IR – Universal Remote‘ app onto his phone via Google Play.
