This project contains two parts:

1- Arduino Code for The Esp32 controller (esp32_control):

• Make esp32 run as a Bluetooth server
• Recieve the readings from the connected accelerometer and classify them based on certian thresholds
• The classifed events could be one of the following: shaking (to finish a task), flip horizentally (swtich to task view when pomodoro mode is on), flip 180 degrees (toggle pomodoro)
• Based on the classifed event, change the LED output and send short messages to the connected Bluetooth device.

2- Andoid app (rainmaker_app):

• Connect to the rainmaker using Bluetooth
• Add, edit, remove tasks in a tasks list, while simultaneously send the updates to the rainmaker device over Bluetooth
• Recieve messages from the rainmaker that contains infromation about the tasks progess

Preparing the hardware:

The following components have been used:
Battery : https://www.adafruit.com/product/2750
Microcontroller : https://www.adafruit.com/product/2821
Orientation Sensor : https://learn.adafruit.com/adafruit-bno055-absolute-orientation-sensor
LED strip : https://www.adafruit.com/product/1138?length=1

Then they are connected as per the following (click on image to show in full size):
