Here's a little program for Arduino Uno: // 2x16 Lcd Display #include "LiquidCrystal.h" // add the LCD library Liquid Crystal lcd (9,8,13,12,11,10); // link 4 bits of data // variables used for tilt detection int portout1 = 2; // the pin OUT1 of the cirest connected to the analog port A2 int portout2 = 3; // the OUT2 pin is connected to the A3 analog port int lectout1; int lectout2; int out1; int out2; void setup () { // Display lcd.begin (16.2); // use a 16 columns and 2 lines screen lcd.clear (); lcd.home (); // line 1, column 0 lcd.write ("INITIALIZATION"); delay (1500); // serial link Serial.begin (9600); } void loop () // Loop { out1 = 0; out2 = 0; // ****************************************** Sequence playback analog ports lectout1 = analogRead (portout1); // read A2 port status lectout2 = analogRead (portout2); // reading the status of the A3 port // ****************************************** Sequence conversion analog state to state binary if (lectout1> 500) { out1 = 1; } if (lectout2> 500) { out2 = 1; } // ****************************************** LCD orientation display sequence if (out1 == 1) { if (out2 == 1) { lcd.clear (); lcd.home (); // column 0, line 1 lcd.write ("HORIZONTAL OR"); lcd.setCursor (0, 1); // column 0, line 2 lcd.write ("PENCHE -> RIGHT"); } else { lcd.clear (); lcd.home (); // column 0, line 1 lcd.write ("DESCEND"); lcd.setCursor (0, 1); // column 0, line 2 lcd.write (""); } } else { if (out2 == 1) { lcd.clear (); lcd.home (); // column 0, line 1 lcd.write ("MONTE"); lcd.setCursor (0, 1); // column 0, line 2 lcd.write (""); } else { lcd.clear (); lcd.home (); // column 0, line 1 lcd.write ("PENCHE -> LEFT"); lcd.setCursor (0, 1); // column 0, line 2 lcd.write (""); } } delay (200); }
