Check out how we used it to replace our air conditioner:
Step 1: How It Works and What We Need
The whole process can be divided into 3 steps. They are:
Pair the Android device to the serial bluetooth on Seeeduino.
Aim the conditioner remote at the infrared receiver on Seeeduino. Press the target key on the remote, for example ON/OFF button, then the Android panel knows how to repeat the command.
Now aim the infrared emitter to the conditioner, press "send" button on the screen. The conditioner should be turned on or off.
Part List (including where you can find them and where to download the app and demo code):
1. Seeeduino V3.0
2. Grove - Base Shield
3. Grove - Infrared Emitter
4. Grove - Infrared Receiver
5. Grove - Serial Bluetooth
6. App & Demo Code(available on Github)
7. Arduino lib for IR remote(import this lib before you upload the demo code)
8. An Android Device(only panel now due to the high resolution picture)
Step 2: Pair-up
Open the APP. Click the first button with a Bluetooth logo on, then a note will pop up for you to select device and enter PIN.
The default PIN is "0000", as the second picture.
Step 3: Study
Step 4: Try It!
Point the infrared emitter to the conditioner. Tap the third button on the screen. What happens to the conditioner? If it reacts to your command, congratulations! If not, back to the "Pair-up" step, and have these all over again.
