We have just launched a short 11 minute AnalysIR video tutorial introducing the use of the Reverse Engineering Tool feature in AnalysIR, which is available via YouTube. The tutorial covers the important points in reverse engineering in infrared signal of a Toshiba Air Conditioner. We focus in on the temperature field and show the process to identify the bits within the signal related to the temperature. Users of AnalysIR can follow this process to reverse engineer their own signals using this powerful tool.
We have just launched a short 6 minute video tutorial for AnalysIR introducing the use of the Checksum Calculator feature in AnalysIR, which is available via YouTube. The tutorial covers the steps to verify the position and type of checksums that are typically found in Air Conditioner infrared signals. The types of checksums covered include:
The sixth and last member of our first MakeIR series of devices & kits is BeamIR the Infrared Light Barrier. This pair of modules is based on an Infrared Light Barrier system with a range of additional applications. In addition to Light Barriers, BeamIR can also be used to deliver solutions involving Security projects, Lap Timers, Laser Tag – invisible trip wire, Photography, Photo Interrupter, Reflective sensors for hand dryers, towel or soap, Dispensers, water faucets, toilet flush, Vending machine fall detection, Virtual ‘fence’, CNC wireless Probes, Security and pet gates, Person or object vicinity activation. BeamIR is built with only the highest quality IR components available and includes constant current drivers, noise suppression circuitry and visual indicators on signal lock.
In Part 1 of this series, we demonstrated how to send signals using soft or Simple Infrared PWM on Arduino. In our Part 2 post we looked at sending RAW IR signals – specifically a RAW NEC signal and a longer RAW Mitsubishi Air Conditioner signal using soft PWM. We have since improved the PWM method shown in Part 1Part 2to provide better performance and improve portability. In this Part 3, we will take the signals from Part 2 and show how to send them using their binary (or Hex) representation, which can save lots of SRAM in many projects, particularly when dealing with longer AC signals.
