Teasmade

Copyright (c) Karl Lattimer License: MIT

This is the code for my Arduino driven Goblin Teasmade upcycle project.

The teasmade is wired to a Arduino Mega with an Arduino WiFi shield and the following I/O configuration;

• Analog clock mechanism coil side A - D35
• Analog clock mechanism coil side B - D33
• Left side LED (red) - D29
• Left side button - D23
• Right side LED (white) - D31
• Right side button - D25
• Teapot microswitch (original mech) - D18
• Kettle microswitch (original mech) - D19

There are also 2 ghetto pixel (blinkm clones) connected to I2C and a DS1307 RTC to maintain the on-device time.

ERROR Codes

Red Light Flashes, fast = 300ms delay, slow = 1000ms delay

• FAST 5 times = Can't make tea, either the kettle is empty or either the kettle or teapot is not present.
• FAST 2 times = Failed to start the SD card reader
• SLOW 10 times = Wifi shield can't be found
• SLOW 3 times = Upgrade wifi shield firmware

States

• Kettle not present - Red light on
• Teapot not present - White light on

Button controls

• Left side button - Make tea
• Right side button - Turn main light on (ghetto pixels, uses a default colour)

Web interface

• /METHODS/MAKETEA - Make tea, returns JSON success
• /STATUS - Return JSON for the current status
• /METHODS/LIGHT/i/#rrggbb - Set ghetto pixel (i 0 or 1) to a specific colour
• /METHODS/TIME/??? - Set the time
• /METHODS/FACETIME/??? - Set the face to the correct time by telling it the current time
• /METHODS/FACENUDGE/i - Nudge the face time by x number of seconds

Files stored on the WiFi shield SD card will be served up as HTML/JS/CSS to the client.
