Arduino uno to Trinket Pro

Post by red41040 »

Hey guys, I just got my trinket pro today and I am having difficulty getting my Arduino Uno code to work. I changed the pins to ones that work on the trinket, but it is still not working. I have attached my code and a picture of the circuit, If anyone has any idea why my code isn't working, your suggestions would be greatly appreciated.

Code: Select all


// constants won't change. They're used here to set pin numbers:
const int buttonPin = 4;     // the number of the pushbutton pin
const int ledPin =  10;      // the number of the LED pin
int brightness = 0;    // how bright the LED is
int fadeAmount = 5;    // how many points to fade the LED by

// variables will change:
int buttonState = 0;         // variable for reading the pushbutton status

void setup() {
  // initialize the LED pin as an output:
  pinMode(ledPin, OUTPUT);
  // initialize the pushbutton pin as an input:
  pinMode(buttonPin, INPUT);
}

void loop() {
  // read the state of the pushbutton value:
  buttonState = digitalRead(buttonPin);

  // check if the pushbutton is pressed. If it is, the buttonState is HIGH:
  if (buttonState == HIGH) {
    // turn LED on:
      analogWrite(ledPin, brightness);    

  // change the brightness for next time through the loop:
  brightness = brightness + fadeAmount;

  // reverse the direction of the fading at the ends of the fade: 
  if (brightness == 0 || brightness == 155){
    fadeAmount = -fadeAmount ; 
  }     
  // wait for 30 milliseconds to see the dimming effect    
  delay(30);    
  } else {
    // turn LED off:
    digitalWrite(ledPin, LOW);
  }
}

Looks like the headers are not soldered. You will need to solder those to get good electrical contact on those pins.
