Title: Digispark not writing to P1-P2
Post by: adrianforest on September 09, 2017, 08:57:42 am

I'm trying to get my Digispark to light three LEDs, on P1, P2 and P5, but right now the only pin it'll write to is P5.

Here's the code:

Code: [Select]

//initialize LED pins
#define green 1
#define yellow 2
#define red 5

void setup()
{
 
}

void loop()
{
 
  digitalWrite(red, HIGH);
  digitalWrite(yellow, HIGH);
  digitalWrite(green, HIGH);
}

and here's my circuit diagram:

Can anyone tell me why I'm only getting output on P5?

Guessing here but you may need to set the pinMode to OUTPUT for each. Don't know why P5 behaves differently.
