+# Gboard Spoon Bending Version
+
+This contains programs, schematics and board layouts for Gboard Spoon Bending Version, which is released on **Apr 1, 2019**.
+
+This is not an officially supported Google product.
+
+# Contents
+
+Directory structure is as follows.
+
+- wireless/
+  - firmware/
+    - Firmware for the wireless version. (coming soon)
+  - board/
+    - Schematic and PCB layout made by EAGLE.
+- wired/
+  - firmware/
+    - Arduino sketch for the wired version.
+- ../third_party/mozc-mageru/spoon_stl/
+   - Spoon shape data for 3D printing.
+
+# Wired Version
+
+## The spoon
+
+Print the spoon under /third_party/mozc-mageru/spoon_stl/ using a 3D printer.
+This is an example design of a flexible spoon that has a slot to embed a
+flex sensor into.
+We have tried it with PLA, but it will probably work with ABS as well.
+
+## Electronic circuit
+
+- Arduino Micro
+- 22k-ohm resistor
+- Flex sensor: FS-L-0055-253-ST (Spectra Symbol)
+
+```
+    Arduino Micro
+
+         5V ---[22k ohm]-------+
+                               |
+         A5 -------------------+
+                               |
+        GND ---[Flex sensor]---+
+```
+
+## How to use the firmware
+
+1. Open the sketch on Arduino IDE.
+2. Choose "Arduino/Genuino Micro" in the [Tools]-[Board] menu.
+3. If you are making Japanse-hiragana version, add ```#define JAPANESE_``` to the first line of the sketch
+4. Upload to board.
+
+## Sensor calibration
+
+1. Open Serial Monitor.
+2. (the home position, which decides when to commit a character)
+   Bend the sensor slightly and send '0'. Make sure the LED turns off when the spoon is not bent by external force.
+3. (the position for the first letter)
+   Bend the sensor slightly a bit more and send '1'.
+4. (the position for the last letter)
+   Bend the sensor to the end and send '2'.
+5. Send 'w' to save the configuration to EEPROM.
+
+# Wireless Version
+
+Coming soon.
