We are delighted to present here a new sketch which implements a basic IR Signal plotter for IRremote. The sketch runs on an Arduino and makes use of the Serial Plotter feature of the Arduino IDE. Although there is no comparison to our powerful AnalysIR application, it may prove useful for beginners to get a quick overview of the shape of their IR remote signals.Continue reading IR Signal Plotter for IRremote & Arduino
Anyone working regularly with IR emitters will eventually come across a situation where they cannot distinguish between similar LEDs of different angles. Here we present one method of Identifying TSAL6100, TSAL6200 and TSAL6400 IR LEDs, based in part on the manufacturing processes used to generate the different angles.Continue reading Identifying TSAL6100, TSAL6200 & TSAL6400 IR LEDs
Our latest product offering is DIYIR an Infrared DIY Soldering Kit. DIYIR, is our new soldering kit to create an advanced IR remote control module for use with Arduino, RPi or any other MCU/Microcontroller system (not included). It uses the same advanced components and circuitry as our other MakeIR modules and works directly with IRremote, IRLib and our own AnalysIR or with your own custom firmware or sketches. It is targeted at beginners, soldering courses and experienced users alike. Soldering skills and/or supervision is required to build the kit. More details along with the tools required are covered in the instructional WiKi pages. We want to encourage makers to undertake IR remote control projects and to provide an affordable way to acquire the very best IR technology for your projects or use with AnalysIR. Popular projects include control of TVs, STBs, Air Conditioner units etc. Continue reading Infrared DIY Soldering Kit launched
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.
In our previous post we showed how to generate stable IR carrier signals using the ESP8266 NodeMCU module. A feature of the original approach was that the output IR signal was inverted and required some additional circuitry to invert it again before transmission. Since the original post we have figured out a method to output a non-inverted or standard IR signal thus removing the need for the additional circuitry. This is achieved by using what turned out to be a very simple setting hidden deep in the ESP8266 UART registers which is covered below. Like all simple solutions it also threw up some other quirks of the ESP8266 NodeMCU, which were eventually overcome with the addition of a simple resistor. The Updated ESP8266 NodeMCU Backdoor uPWM Hack for IR signals is detailed below – including updated source firmware, new circuit diagram and explanation of the ‘quirk’. Read on….
We received our ESP8266 NodeMCU several months ago it has been difficult to find a working example of Hardware PWM to generate crisp Infrared carrier signals. Most posts we have read suggest that there is no PWM readily available on any of the supported platforms. As we have already shown with Arduinos and the Particle Photon we figured it would be possible to use a spare UART pin on the ESP8266 NodeMCU to achieve our goal. After some initial success we encountered some watchdog timeouts/resets and it seemed like the uPWM hack would not be possible on the ESP8266 Node MCU platform. For a few weeks we ‘parked’ the effort and today we decided to try again with all of the latest and updated firmware available from the ESP8266 community via the Arduino IDE. This time we were successful and the ESP8266 NodeMCU Backdoor uPWM Hack for IR signals using works!
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.
