Component Needed:

• Huzzah Feather
• TFT Featherwing
• M2.5 Screws
• Kitchen Case and Cover 3D files
• 3.7 Lipo 500mAh battey
• Small dab of mounting putty
• Glue
• Tactile button (7mm height)
• On/Off Switch
• USB wall charger and USB cable
• 0.1 uF capacitor, 200K resistor, 1M resistor

Steps

1. Upload the kitchen_unit.ino file to the Huzzah selected for the Kitchen Unit (this Huzzah will use regular headers). 
2. Load images onto the SD card. Insert the card and the feather onto the TFT Featherwing. 
3. Plug in the unit and connect to the CompostProfessor_XXX wifi network to set-up wifi and ensure that the code works.
4. Solder the on/off switch, tactile switch, and voltage measuring components (resistors and capacitors) as indicated in the diagram below. (Note - the TFT Featherwing has inputs for jumper cables. You can solder jumper cables to the end to insert into the proper Feathering holes).
5. Place the button and on/off switch into the case. The on/off switch will click into place. You will need to secure the reset button with a small dap of glue, or better, by screwing a small screw underneath the button from the rear.
6. Insert the battery and use a small dap of mouting putty to keep the battery in place.
