So I found the schematic for the shield I have, it is the kegboard-mini, and the schematic can be found here -> https://github.com/Kegbot/kegboard/blob/master/hw/kegboard-mini/kegboard-mini-board.pdf?raw=true
Now after reading / looking at the schematic I am assuming I would apply a high voltage to the LED to see it light up, but no dice so far. Am I looking at this thing the wrong way?
My Arduino sketch looks like the following,
/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.
This example code is in the public domain.
*/
// pin D2 - should be connected to the flow_A LED
// give it a name
int led = 2;
// the setup routine runs once when you press reset:
void setup() {
//initialize the digital pin as an output.
pinMode(led, OUTPUT);
}
// the loop routine run over and over again forever:
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for one second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
