Instruction video : Make an Arduino based game controller Arduino Script: // Monkey Game controller - By Jee Van Kur is not a Monkey ;) const int button[] = {10, 11, 12}; // pins int i = 0; void setup() { Serial.begin(9600); while(i<3) // define pins { pinMode(button[i], INPUT); digitalWrite(button[i], HIGH); i++; } } void loop(){ int sum = 0; for(i=0;i<3;i++) { if(digitalRead(button[i]) == LOW) sum += (i+1)*pow(2, i); // sum up the pressed button indexes } Serial.println(sum); // print value delay(50); } // I am of no use without proc...
