Example Codes

Light up all gems in sequence

In this code, an array of pins is declared of type char. A for loop is initiated to cycle through pins A-L on the Tinkerstruct board. i is used as an iterator and is incremented by 1 in every repeat of the loop (i++). The pin() function is called to switch on the pin, to delay 100ms and then switch the pin off for every loop.

void setup() {
  // This is the tinkerstruct base PIN mapping. DO NOT edit this unless you know what you're doing:
  #define A PA0
  #define B PA1
  #define C PA2
  #define D PA3
  #define E PA4
  #define F PA5
  #define G PA6
  #define H PA7
  #define I PA8
  #define J PB6
  #define K PB7
  #define L PC14
  #define M PC15

  // Setting up the GPIO pin modes: 
  pinMode(A, OUTPUT);
  pinMode(B, OUTPUT);
  pinMode(C, OUTPUT);
  pinMode(D, OUTPUT);
  pinMode(E, OUTPUT);
  pinMode(F, OUTPUT);
  pinMode(G, OUTPUT);
  pinMode(H, OUTPUT);
  pinMode(I, OUTPUT);
  pinMode(J, OUTPUT);
  pinMode(K, OUTPUT);
  pinMode(L, OUTPUT);
  pinMode(M, OUTPUT);

  // Setting up some helper aliases
  #define ON HIGH
  #define OFF LOW
  #define pin digitalWrite
}

void loop() {
  // This is user code land, put your code here.
  char pins[] = {A, B, C, D, E, F, G, H, I, J, K, L, M};
  for (int i=0; i<12; i++){
    pin(pins[i], ON);
    delay(100);
    pin(pins[i], OFF);
  }
}

Light up a random gem (out of the first 6)
