Hi! I’m Neoxelox, and today I will show you how to control your BLINDS (Pull up/down and stop) with Cayenne IoT, and with it’s schedule manager make an Sun natural alarm clock!
We need:
-
Cayenne Acccount
-
IR Emitter (Mine is KEYES IR Emitter)
-
Arduino (Obviously)
-
Ethernet Arduino Shield
-
Blinds that can be controlled through IR
-
IRremote library: Arduino-IRremote-master (1)
Step 1: Connect the IR Emitter to Arduino and also the Triggers
Connect the IR Emitter to Arduino board.
Pinout:
IR Emitter / Arduino
pin “-” —> pin GND
this pin doesn’t have any letter so, the middle pin —> pin 5V
pin “S” —> digital pin 3 or other digital pin (It cannot be pin 0,1,2 or 13)
Triggers:
I was thinking what is the easiest way to do this project, and I realized if we connect a wire through digital pin 9 to 8 and digital pin 7 to 6 is the best way to do it, so:
Connect Arduino digital pin 9 to Arduino digital pin 8, repeat with 7 to 6.
Step 2: The Code
As you can see my Blinds Remote Control has 3 options:
Just copy that (Obviously you need to change the line 33 with your IR Emitter digital pin.
And also you have to know what speed you IR Emitter works with (mine 38 khz).
And one thing important is that you have to know what are your Blinds IR Raws, I mean the numbers that represent the action “Pull Blinds Up/Down and Stop”. If you don’t know this, you can dumb your remote control with this library and with a IR Receiver (In the library you have and example of “Dump”, just execute that and press the buttons of your remote control).

Cayenne Button Widget Example
This sketch shows how to set up a Button Widget with Cayenne.
The Cayenne Library is required to run this sketch. If you have not already done so you can install it from the Arduino IDE Library Manager.
Steps:
1. In the Cayenne Dashboard add a new Button Custom Widget.
2. Select a digital pin number. Do not use digital pins 0 or 1 since those conflict with the use of Serial.
3. Attach a digital output device (e.g. a LED) to the digital pin on your Arduino matching the selected pin.
4. Set the token variable to match the Arduino token from the Dashboard.
5. Compile and upload this sketch.
6. Once the Arduino connects to the Dashboard you should be able to control the digital output device with the Button widget.
Notice that there isn't much coding involved to interact with the digital pins.
Most of it is handled automatically from the Cayenne library.
For further examples of how to receive data from Cayenne see the example sketches under Actuators.

Step 3: Set Up Cayenne IoT Buttons
Set Up Cayenne IoT Buttons as the images show.
PD:
You DON’T need a third button called “Stop”, because when you are NOT pressing any of the other buttons the blinds will STOP.
Step 4: Test it and you FINISH!!!
Test it and you will finish!! Hope you like it!!
PD:

Step 5: (OPTIONAL) You can make a Sun natural alarm clock
You can make a Sun natural alarm clock with Cayenne’s Scheduler manager, just click option button in the Pull Blinds Up, and press Schedule. Then modify it as you want. The blinds will Pull Up, and all the solar light will enter into your room.
