It's weird sometimes how that works. You worry about the stuff you are trying to learn and something simple like a bad LED scorches you.. Been there.
Well done!

 

Thank you again for all the help. I am in programming course and most of my bugs are ";" or syntax errors .

And it was 3 bad leds.....

 

This is why reliable test equipment is essential to make this hobby a lot easier. You don't need to spend a fortune. Start off with a logic probe and / or voltmeter. Later yo might want to add a scope and a logic analyzer. If anything they are a lot of fun to play with. My logic analyzer is a pain to setup but once done I really like using it. It has helped me out of a jam more than once.

 

Hello. This is my first time messing with a microcontroller. I am trying this tutorial:

CIRCUIT: http://postimg.org/image/lasta61k1/
CHIP: 12f683
COMPILER: mikroC PRO for PIC v.6.6.1

I write the program just fine but the led does not work.
I might be doing some stupid mistakes but its my first time so don't shop my head of please.

code:

void main(void) {
      TRISIO.B2 = 0;
      while(1)
      {
              GPIO.B2 = 1;
              Delay_ms(1000);
              GPIO.B2 = 0;
              Delay_ms(1000);
      }
}

Here is a working example Led @ pin 5
I also include an ADC example and explanation in short hand.
Small advice: please use microchip xc8 compiler its free and works good.
The free version is able to fulfil most of the hobbyists needs.

Good luck.

// Xc8 compiler
#include <htc.h>
#include <pic12f675.h>
#include <xc.h>
#define _XTAL_FREQ 4000000  // Needed for delay_ms macro
 
//#pragma CONFIG(FOSC_INTRCIO & CP_OFF & MCLRE_ON & WDTE_OFF); << depending from your wishes

#define Output GPIO5
#define Voeding_On GPIO4
#define Led GPIO2  // pin5

int Wanted_value;
int cnt;
int Flash;
unsigned int result;

Please use code tags. Put [ code] and [ /code] (without the spaces) around your code. You can specify that it is C by starting with:
