I am working on hooking up one button to turn on /off the led on pin 13. I have tried pin 10-12 and 3-6 for the button to ground. I have checked continuity on my header, my connection wire, my bread board and my button, all is well. For whatever reason the pin never reads LOW. What am I missing!? Is there any other way to troubleshoot this. My goal is to create a little game controller by hooking up 4 buttons. This is happening on more than one of my Trinket Pro boards on Linux and Windows. BTW I am able to load up the blink example and modify it so I know I am getting code on the board. I did notice some mention of an RX bug... but not sure if that is relevant to my issue... any help would be greatly appreciated. Below is my code. Pretty standard stuff. Perhaps I have a bad board?
Code: Select all
const int PIN_BUTTON = 12;
void setup()
{
pinMode(LED_BUILTIN, OUTPUT);
pinMode(PIN_BUTTON, INPUT_PULLUP);
}
void loop()
{
if (digitalRead(PIN_BUTTON) == LOW)
{
digitalWrite(LED_BUILTIN, HIGH);
}else{
digitalWrite(LED_BUILTIN, LOW);
}
}
