Hello, big-brained sexual dynamos of the Arduino forums! I bring to you a problem that I'm 99% sure is going to be a simple fix, but I CAN NOT, FOR THE LIFE OF ME, figure it out. I'm attempting to fire one of these laser diodes (650nm 5mw) with a button, using the below code. int pinButton = 4; //the pin where we connect the button int LASER = 12; //the pin we connect the LASER void setup() { pinMode(pinButton, INPUT); //set the button pin as INPUT pinMode(LASER, OUTPUT); //set the LASER
