IOT button

A wireless, battery driven hardware device with 3 buttons and a small screen.

One plus button (+), one minus (-) button, and one Enter button (Enter).

When you press the plus button one time, the screen should update to "1". If you press it again it should display "2" and so on.

When pressing the minus button while the display shows "0", nothing happens. However, When pressing the minus button the displaying number should decrement by one.

When pressing the "Enter" button, the displayed number should be sent to an external server/database.

The device needs a wifi connection.

Skills: Bluetooth Low Energy (BLE), Internet of Things, Raspberry Pi, Software Architecture, Wireless
