Iteration over digital inputs.
Iteration with a "for" structure over input pins. button switches are wired from pins 0 to 3 depending the number of pressed buttons a variable named "force" will hold different values from 0 to 4

int force; void setup() { Serial.begin(9600); for(int i = 0; i<4; i++) { // sets pins 0-3 as inputs pinMode(i, INPUT); } } void loop() { force = 0; for(int i = 0; i<4; i++) { // calculates how many buttons are pressed if(digitalRead(i) == HIGH) { force = force + 1; // add 1 to force if the button is pressed } } Serial.print("force is: "); // print the force value Serial.println(force); delay(200); // wait 200ms for next reading }
