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)→
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!
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.
The final member of our first MakeIR series of devices & kits is the A.IR Shield Photon. This shield works out of the box with AnalysIR and is essentially plug & play, with additional prototyping options. The shield plugs into a (Particle) Photon with headers or pin-compatible clone. Although designed specifically for AnalysIR, users can also upload any sketches that run on the Photon for Infrared remote control projects by customising the included firmware. A.IR Shield Photon is built with only the highest quality IR components available and boasts dual Infrared emitters with configurable IR Power. The supplied firmware supports hardware PWM for sending IR signals.
We have provided a link below to the preliminary 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 Photon shield.
Since we received our Photon several months ago it has been difficult to find a working example of Hardware PWM on the Photon. Initially, we ported our softPWM approach to the Photon, which is excellent. However, we figured it must be possible to use at least one of the spare UARTs on the Photon to achieve our goal. So first we started prototyping on the Arduino and quickly got a working example with some limitations – only 40 kHz and 33 kHz carrier frequencies were possible with the UART without delving into the registers a bit more. Then we moved the code over to the Photon, leveraging our previous softPWM examples, upgraded with the Arduino code – EUREKA! The Backdoor uPWM Hack on Photon for Infrared signals.
The fifth member of our MakeIR series of devices & kits is the A.IRShield Nano. This shield works out of the box with AnalysIR and is essentially plug & play , with additional prototyping options. The shield comes attached to an Arduino nano compatible device (clone). Although designed specifically for AnalysIR, users can also upload IRremote, IRLib or any Arduino sketches that run on the Nano. A.IR shield is built with only the highest quality IR components available and boasts dual Infrared emitters with configurable IR Power.
Dublin, Ireland – 17th April 2015. We are happy to announce the latest release of AnalysIR V1 preview #2 is now available for download by our backers & supporters. Existing users of AnalysIR will receive an email with instructions on how to download this version. New users will receive the details as part of the registration process.
A major highlight of this release is full AnalysIR support for our soon to be released LearnIR (IR Learner). LearnIR delivers the best performance available for receiving and sending Infrared signals with excellent accuracy.
Having helped many makers resolve problems with Infrared remote control projects over on the Arduino forum, we decided to put 2 of the more common 38kHz receivers, TSOP34438 vs VS1838B, ‘head-to-head’ over 3 rounds in a winner takes all contest. Different people report a wide variety of problems when first attempting infrared remote control, resulting from using the wrong receiver to timer or interrupt conflicts between the various libraries available. Our commentary on the ‘face-off’ will hopefully shed some light on the ability of these 2 common Infrared receivers to deliver results, as expected.
