LiBoard - Arduino library

This Arduino library provides the code running on the board's microcontroller.

Installation

Clone this repo into YOUR_ARDUINO_FOLDER/libraries/.

Usage

If you're just interested in using the board with a script or the app, you'll want to run the serial_binboard sketch from the library's examples folder.

Thresholds

Each photoresistor requires a threshold value which triggers when each square is occupied or not. There are two options you can use to set the threshold values for each square.

Setting Threshold Mode

By default, Liboard is configured to use the Global threshold mode. If you want to change it Per-Square thresholds, then edit the following variable:

// !!! choose mode: 1 = global single value, 0 = per-square array !!!
#define USE_GLOBAL_THRESHOLD 1

Option 1 - Global Threshold

Global Threshold mode applies the same threshold value to every photoresistor. If you need to change the sensitivity of the photoresistors, change the value of this variable:

// Option 1 - Global Threshold (Applies to all photoresistors)
unsigned short THRESHOLD = 100;

Option 2 - Per-square Thresholds

You can also set individual thresholds for each photoresisor. This is useful if not all your photoresistors are the same type. Per-square thresholds also has more accuracy. You can adjust each square threshold individually by editing each number.

// Option 2 - Per-square threshold (Applies to each individual photoresistor)
unsigned short THRESHOLD[64] = {
  // A1..H1
  150, 150, 150, 150, 150, 150, 150, 150,
  // A2..H2
  150, 150, 150, 150, 150, 150, 150, 150,
  // A3..H3
  100, 100, 100, 100, 100, 100, 100, 100,
  // A4..H4
  100, 100, 100, 100, 100, 100, 100, 100,
  // A5..H5
  600, 600, 600, 600, 600, 600, 600, 600,
  // A6..H6
  600, 600, 600, 600, 600, 600, 600, 600,
  // A7..H7
  300, 300, 300, 300, 300, 300, 300, 300,
  // A8..H8
  300, 300, 300, 300, 300, 300, 300, 300
