### Board render
Render of the controller board. It measures 2.05x2.30 inch
Render of the display board. It measures 3.70x1.60 inch.
## Arduino
The source can be found under `firmware`. It's build with Arduino 1.6.5, but newer versions should work too.
You need the following libraries:
* [CommandLine](https://github.com/basilfx/Arduino-CommandLine)
* [Timer1](http://playground.arduino.cc/Code/Timer1)
### Firmware
To be done.
### Hardware configuration
For best performance, the light gate should be fitted in a tube, where environment light has little effect.
To calibrate the device, check the [calibration](https://github.com/basilfx/Arduino-BeerCounter/blob/master/docs/Calibration.md) guide.
### Firmware configuration
Once you have the device ready, connect it to the computer via a serial adapter. Hold the setup button, and power cycle the device. The settings for terminal are 115200 baud, 8 bits, no parity and 1 start/stop bit. The terminal has the following commands:
* reset — Reset the device
* count — Get/set the initial count
* zeroes <1|0> — Enable/disable leading zeroes
* restarts — Get the number of power cycles
