We are excited to announce our newest product KontroLIR – the first Arduino compatible IR remote control. Users can now design their very own Infrared remote to work exactly how they want. The possibilities are unlimited. Customize the fully featured firmware within the Arduino IDE to your own needs or just add your own signals to the pre-configured 5 device/225+ buttons. Sketches are uploaded over Serial USB I/F from the Arduino IDE – just like any other sketch. KontroLIR features an ATmega328PB, a high power emitter, an indicator LED and is powered by 2xAAA alkaline batteries. Low power operation is already implemented with ~1uAmp idle current for long battery life. Available options include IR Receiver, IR Learner, 16 to 256KBytes I2c EEPROM and a serial USB adapter for uploading your sketch from the IDE. KontroLIR supports IRremote, IRLIB and is tightly integrated with our own AnalysIR Application.
Following the release of our highly popular A.IR Shield Nano, we have received numerous requests about using the module with platforms other than Windows. Because the module uses a standard Serial USB interface for communicating, experienced users can easily integrate it into any other platform. To assist other users we have now released an A.IR Shield Nano Python Script. Continue reading A.IR Shield Nano Python Script – Raspberry Pi (RPi)→
The latest member of our MakeIR series of devices & kits is the A.IR Shield ESP8266/ESP32 Tx. This shield works out of the box with AnalysIR and is essentially plug & play, with additional custom Firmware options. This shield is a ‘sibling’ to our related TRx shield, and features IR multi-send only vs the send & receive of the TRx shield. The shield plugs into a Wemos D1 Mini (ESP8266) with headers or any pin-compatible clone (e.g. ESP32 Mini D1). Although designed specifically for AnalysIR, users can also upload any sketches that run on the ESP for Infrared remote control projects by customising the included firmware. A.IR Shield ESP8266/ESP32 Tx is built with only the highest quality IR components available and boasts dual Infrared emitters with configurable IR Power. The supplied firmware uniquely supports hardware PWM for sending IR signals (on ESP8266). Continue reading Preview: A.IR Shield ESP8266/ESP32 Tx, a high-end IR Shield→
We have posted a brief 4 minute “Using AnalysIR with Flirc – Video tutorial” showing how to use the Flirc USB device as an Infrared remote control signal source for AnalysIR. The video is available now via YouTube, by clicking the image below. The tutorial covers the semi-automatic method we have used to support this feature, which should greatly enhance the Flirc Device and enable more troubleshooting with problematic signals or just simply as an additional powerful feature for the Flirc device. There is no need to update your Flirc installation or firmware, provided you have the latest revision installed.

We have provided a link below to the product data sheet and would welcome feedback on additional, nice to have or missing features, if any. Please read the data sheet for a more detailed description of the A.IR ESP8266 TRx shield. The shield is now available to purchase via our web shop.
Although designed to work with AnalysIR, users can customise the provided firmware to send and receive IR signals via web requests, thus making integration into projects easy. More advanced users can integrate into platforms like Alexa or similar.
Also check out our example for creating your own IR send sketch for a variety of Signals (Air Conditioner, HEX, RAW & protocol based) using this shield with a Wemos D1 Mini or any ESP8266.
One of the most popular projects involving Infrared remote control, is to use an Arduino to control an Air conditioner (AC) system. However, AC signals are usually very long and take up a lot of SRAM on a standard Arduino. Experienced users will go about reverse engineering the AC protocol to make the sketch fit within the 2K Bytes of SRAM. Many hobbyists will struggle, even with the help of tools like AnalysIR to guide them. In this post we cover sending long AC Signals from Flash with IRremote. IRremote (along with IRLib) is a popular open-source library for sending and receiving IR remote control signals with Arduino. The demo code covered in this sketch extends our previous sendRAW example by demonstrating how to store many long AC signals in Flash with little or no SRAM overhead.
A few months ago a new user to AnalysIR, from Canada, asked us to assist in adding ESP8266 NodeMCU Infrared decoding over WiFi into AnalysIR. We set about making some upgrades to AnalysIR for this and in double quick time he had AnalysIR accepting IR signals from the ESP8266 over WiFi. He stressed the ease of use of the support within the Arduino IDE for ESP8266 devices and he wasn’t kidding. This motivated us to go and order an ESP8266 for US$3.60 including shipping from Aliexpress. Just the other day the NodeMCU arrived, presumably delayed somewhat by the extended XMAS holidays & celebrations, in this part of the world. So we set about porting our existing firmware for Arduino & Photon over to the new device.
Marco is a volunteer for an organization (NSW Australia) that builds custom aids for people with disability, and has recently been looking at a project to create a ‘very large button’ IR remote control for a cable TV Set Top Box (STB). The custom unit needed basic functions (Channel Up/Down, Volume Up/Down and Power On/Off). Commercially available large button remotes have buttons that are still too small and/or they have too many buttons. Soon he hit a roadblock trying to capture some difficult Foxtel signals and searched all over the web looking for a solution. Needless to say, nothing worked out for him until he came across AnalysIR via Google. Once he started Troubleshooting the Big Button Infrared remote control with AnalysIR the root cause of his problems became obvious.
In recent years we have responded to hundreds of supports requests on the Arduino Forum, GitHub and elsewhere for many recurring issues with IRremote – the library for Infrared remote control. As many of the issues are similar we decided it was time to develop a ‘IRremoteInfo a Helper utility for troubleshooting IRremote’ that will help users resolve their own issues or failing that, provide solid support information to those who are providing free support services. Today we release the first version of IRremoteInfo, which prints the settings for most of the relevant parameters within the IRremote library, in the hope that users seeking support can post or upload this information when seeking assistance on-line.
