24-Segment-Analog-Clock

7-Segment-Digital-Clock_Analog-Patch

This is the source and schema for a homemade analog clock I've made. The code is based on this.

In daylight it's not very bright. To control the clock you can use a bluetooth terminal of your choice or my app.

App

Feel free to modify my app like you want to. Source code

If the app asks you to enable bluetooth, the devices wont display after you allowed it, first you need to reload the current site.
Press on the Devices button to reload the site (works on other sites too).

App permissions:

The App needs following permissions:

• <uses-permission android:name="android.permission.BLUETOOTH" />
• <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
• <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
• <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

Bluetooth should be logical. The app will ask befor enabling Bluetooth or access the storage. The storage is used to save some values (see site advanced). You can save and load color values.
The values will be stored in most cases to /storage/emulated/0/AnalogClockV1/config.json, just open a file explorer and navigate to internal storage. anywhere there you should find the folder AnalogClockV1.

Hardware

The resistor R1.1 need to be a pull UP resistor!
I'll fix the plans (wiring, pcb, perfboard (AnalogClockV1.fzz)) later (with the ext. EEPROM update I'm working on)
(Btw, the cirquit worked with even no resistors...)

See wiring folder for sketches

Commands

To send a command to the clock, you need to wrap it into this characters: ||

Synthax:

| Command,arg0,argN|

Command	Arguments	Description
PING	none	Returns |STATUS,(some parameters\*)|. Its for the app (to check if right device, for different versions, ...)
RESET	none	Restarts the Arduino (like pushing the reset button or put the reset pin high)
CLOCK	none	Set mode to 0 (Display time)
TEMPERATURE	none	Set mode to 1 (Display time and temperature)**
HUMIDITY	none	Set mode to 2 (Display time and humidity)**
SCOREBOARD	L, R	Set mode to 3 and Set score of L and R (both type integer, 0 ≤ n ≤ 99)
TIMER	none	Set mode to 4 and start/ stop timer (Returns |TIMER,(timerRunning as int)|)
MODETOGGLE	none	Define, if the clock toggles every 5 seconds between mode 1 and 2 (Returns |MODETOGGLE,(modeToggle as int)|)
RTC	Y, M, D, h, m, s	Set time. No leading zeros required (Year, Month, Day, Hour, Minute, Second)
COLOR	target, r, g, b	Set rgb color of target (B, P, S)***
BRIGHTNESS	target, value	Set brightness of target(B, H, 0, 1, 2, L)****

*For parameters see AnalogClockV4 » processBtBuffer() » if PING [#L218]

**If modeToggle is true, the clock toggles between temperature and humidity.
***List of color targets:

• B: Background
• P: Hour dot (pointer) & Score left
• S: Minute dot(s) (pointer) & Score right

****List of brightness targets:

• B: Background
• H: Hour dot (pointer)
• 0: Minutes dot (offset 0)
• 1: Minutes dot (offset 1)
• 2: Minutes dot (offset 2)
• L: Set background lighting:
  • 0: Off
  • 1: Quarters
  • 2: All
