        # goto-bed

Making my melatonin bottle vibrate so I know its time to go to bed.

I just wanted a little project to work on to learn Fusion 360 and a bit of KiCad.

  

## General Concept

- Send NTP request to get current time and resync every 5 minutes

- If current time equals alarm time, trigger vibration motors

- Press function button to acknowledge alarm, stop vibration motors, and reset state

- Take melatonin, get tired, and go to bed at a reasonable time (ideally)

### Setting the Alarm Time

- Press function button to transition to edit state

- Use potentiometer to set alarm time

- Press function button again to reset back to normal state

## Learned

This stupid project definitely made me learn some things.

- Analog read from potentiometer

- Fetch current time using UDP packet to NTP server

- Design a 3D printable enclosure with Fusion 360

- Make a schematic in KiCad with Eeschema

## Cut From Project

I wanted to do a couple more things, but decided to cut it short due to time.

- Power the circuit with rechargable battery (also redesign for low power usage)

- Design and order custom PCB

- Smaller enclosure => my enclosure design is disgustingly large

- Power switch
