Thanks, but I personally don’t like Arduinos. So I am never gonna work on those.

Hope I'm not wrong... Hi,
Just wanted to point out that ADCSRA should be set as:

ADCSRA=(1<<ADEN)|(1<<ADPS2)|(1<<ADPS1)|(1<<ADPS0); //Enable ADC with Prescalar=Fcpu/128

You did not shift 1 by ADPS1 and ADPS0 in the explanation while it is written correctly in the code.
Hope I'm not wrong…

The operation x<<n shifts the value of x left by n bits. If REFS0 is initial 0 then 1 is shifted to the left by 0 positions. So in the right-hand side we have the bit value 1 and this value is assign to ADMUX(a register with 8 bits).Is this possible? I'll appreciate if you could help me figure out this problem. Thanks.

I am using this equation percent=(adc_result1*100)/1023. I get my percentages right, but the problem is that after 64 percent it jumps to 1 percent again, I was wondering if you could help me figure out the problem.
