Building the alarm clock

Estimated build time: 30 minutes.

Connect the rotary encoder knob

The rotary encoder knob is used to set the alarm time. Press is to set or unset the alarm. 

Connect its CLK (Clock) pin to signal pin A0, connect its DT (Data) pin to signal pin A1, and connect its SW (Switch) pin to signal pin A2.

Connect the motion sensor

Connect its middle pin to signal pin 3.

The motion sensor will be able to detect movement in bed. When it detects movement close to the internet wake up time, it starts the wake-up procedure.

Connect the OLED screen

Connect SDA (Signal Data) to signal pin A4 and SCK (Signal Clock) to signal pin A5.

Plug in the Arduino

Plug in the RF-Nano Arduino

Plug the RF-Nano into its socket. The USB connector should be on the outside of the main board.

Open the Candle Manager

Select the Candle Manager from the menu, and follow the steps. It will help you upload the code to your new creation.

Add your new device

Visit the Candle controller and on the things page press the (+) icon. Your new creation should be available. Optionally, select which of its properties you'd like to have in the spotlight. Click on "save" to complete the proces.
