# BikeLightDuino <p style="font-size:12px">8x8 Matrix led example</p> ### This code shows a series of sequences for 8x8 led matrix format designed to be used as a bicycle's backlight. It's serial controlled using serial commands L, H, R, A, V, B and S. <a href="https://github.com/neverhags/BikeLightDuino/blob/master/image.gif"><img alt="BikeLightDuino image" src="https://raw.githubusercontent.com/neverhags/BikeLightDuino/master/image.gif" style="width:250px" width="250"/></a> * ### GitHuh code: https://github.com/neverhags/BikeLightDuino * ### Youtube Videos: + https://www.youtube.com/watch?v=1YXSK_jz2z0 + https://www.youtube.com/watch?v=EW2J3FLwelY * ### Android App: https://play.google.com/store/apps/details?id=es.bikeLightDuino (Accelerometer Controlled) ## This code provides 4 display modes: * Hold [H]: Running * Left [L]: Turn Left * Right [R]: Turn Right * Stop [A]: Before I Crash/Die ## Other features: * [S]: Serial On/Off * [V]: Needs Less Light to Turn On * [B]: Needs More Light to Turn On All commands must be sent using the serial port on pin 10 (RX) and 11 (TX), you could connect a WiFi or Bluetooth to control it: SoftwareSerial SerialBT(10, 11); // RX, TX ## Pinout: // Define all columns and rows pins #define COL_1 0 #define COL_2 1 #define COL_3 12 #define COL_4 13 #define COL_5 A0 #define COL_6 A1 #define COL_7 A2 #define COL_8 A3 #define ROW_1 2 #define ROW_2 3 #define ROW_3 4 #define ROW_4 5 #define ROW_5 6 #define ROW_6 7 #define ROW_7 8 #define ROW_8 9 #define SENSOR_PIN A4 This project uses a photoresistor in pin A4 to turn on/off the matrix. It can be controlled using V and B commands to adjust the intensity in real: int sensorValue = analogRead(SENSOR_PIN); *Note: I am not using EEPROM, if you want to save the config you must program that feature.*
