KontroLIR – the first Arduino compatible IR remote control

KontrolIR - the first  Arduino compatible IR remote control (Arduino Compatible)
KontroLIR

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.

IR Signal Plotter for IRremote & Arduino

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.

ESP8266 NodeMCU Backdoor uPWM Hack for IR signals

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!
