John - I tried uploading the Blink program as written shown below... It says it uploads and is running, but no blinking on the board. Hence thinking a LED is not on board, I changed it to digital output 5 wired a LED to output 5 with a 220 ohm resister and nothing.
Original Blink wont run....
// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
